▼ Deploying and managing high availability-tiered application in the
cloud is challenging, as it requires providing necessary virtual machines to make the application available. An application is available if it works and responds in a timely manner for varying workloads. Application service providers need to allocate specified number of working virtual machine copies for each server with at least a given minimum
computing power, to meet the response time requirement. Otherwise, we may end up with response time failures. This thesis formulates an optimization problem that determines the number and type of virtual machines needed for each server to minimize the cost and at the same time guarantees the availability SLA (Service-Level Agreement) for different workloads. The results demonstrate that a diverse approach is more cost-effective than running on a single type of virtual machine, and buying only the cheapest virtual machines for an application is not always economical.

▼ The outsourcing of data storage and related infrastructure to third-party services in the
cloud is a trend that has gained considerable momentum in the last decade due to the savings it affords companies in both capital and operational costs. Although encryption can alleviate some of the privacy concerns associated with
cloud storage, it comes at the cost of decreased utility of data once it is in the
cloud. For instance,
cloud services for searching over a large set of files are useless when those files are encrypted using standard, randomized techniques. Moreover, even though the files are encrypted, the historical access pattern over a data set (e.g., file access times/frequency, memory read/write locations) can leak significant information to malicious parties that can be combined with other metadata to partially reveal the file contents.
Two research thrusts that address these issues are Symmetric Searchable Encryption (SSE) and Oblivious RAM (ORAM). SSE schemes provide an efficient means for searching over encrypted data that is stored on an untrusted server. These schemes, however, are inherently susceptible to statistical attacks by observing the history of de- terministically encrypted search queries, along with the access pattern resulting from those queries. ORAM, by design, can prevents such leakages, but it introduces high communication overhead, among other challenges.
In this work we introduce new ORAM schemes tailored for more efficient private access to tree data structures, which are commonly used as search indexes. We make multi-faceted contributions that include: (i) a formal definition for obliviousness in the relaxed setting where the external storage provider knows we are accessing a tree data structure, (ii) a formal proof showing that our schemes satisfy this definition, with an- alytical and empirical results showing that we reduce transmission overhead by several factors over state-of-the-art ORAM schemes, and (iii) a Python software package called PyORAM (Python-based Oblivious RAM) that provides researchers with a powerful set of tools to build upon current ORAM methods tailored for the
cloud storage set- ting. Our work has broad impacts for searchable encryption via private database search with reduced transmission requirements, which is vital for privacy-critical applications in governmental and healthcare systems.

▼ In the next generation of
Cloud computing systems, it is expected that multiple
Cloud Service Providers (CSPs) will cooperate together to advertise their services and prices to their end users, which may choose the one that best meets their budgetary and technical needs. Despite this benefit of having multiple CSPs to select from, several issues may arise. For instance, how does an IT entrepreneur select a CSP to offload his/her service request?
How does the underlying Inter-
Cloud system handle this service request? To address these questions, this thesis proposes a novel Optimal
Cloud Broker design for Inter-
Cloud Systems in the form of a Semi-Markov Decision Process (SMDP) based model. Under the long-run expected average cost criterion, the optimal policy is derived, which aim at maximizing the overall virtual machine utilization while giving the end users the best possible prices. The effectiveness of the proposed Broker design is validated by numerical results.

A Universal Architecture for Cross-Cutting Tools in

▼ Recent research has proposed a variety of
cross-cutting tools to help monitor and troubleshoot end-to-end
behaviors in distributed systems. However, most prior tools focus
on data collection and aggregation, and treat analysis as a
distinct step to be performed later, offline. This restricts the
applicability of such tools to only doing post-facto analysis.
However, this is not a fundamental limitation. Recent research has
proposed tools that integrate analysis and decision-making at
runtime, to directly enforce end-to-end behaviors and adapt to
events. In this thesis I present two new applications of
cross-cutting tools to previously unexplored domains: resource
management, and dynamic monitoring. Retro, a cross-cutting tool for
resource management, provides end-to-end performance guarantees by
propagating tenant identifiers with executions, and using them to
attribute resource consumption and enforce throttling decisions.
Pivot Tracing, a cross-cutting tool for dynamic monitoring,
dynamically monitors metrics and contextualizes them based on
properties deriving from arbitrary points in an end-to-end
execution. Retro and Pivot Tracing illustrate the potential breadth
of cross-cutting tools in providing visibility and control over
distributed system behaviors. From this, I identify and
characterize the common challenges associated with developing and
deploying cross-cutting tools. This motivates the design of baggage
contexts, a general-purpose context that can be shared and reused
by different cross-cutting tools. Baggage contexts abstract and
encapsulate components that are otherwise duplicated by most
cross-cutting tools, and decouples the design of tools into
separate layers that can be addressed independently by different
teams of developers. The potential impact of a common architecture
for cross-cutting tools is significant. It would enable more
pervasive, more useful, and more diverse cross-cutting tools, and
make it easier for developers to defer development-time decisions
about which tools to deploy and support.

▼ Innovations are necessary to ride the inevitable tide of change. Most of organizations
are striving to reduce their computing cost through the means of virtualization. This
demand of reducing the computing cost has led to the innovation of Cloud
Computing. Cloud Computing offers better computing through improved utilization
and reduced administration and infrastructure costs. Cloud Computing is the sum of
Software as a Service (SaaS), Infrastructure as a Service (IaaS) and Platform as a
service (PaaS). In a nutshell, it’s a computing model based on utility Computing.
Cloud Computing is still at its infant stage and a relatively new technology for the
organizations especially the non-governmental organizations in Kenya. Therefore,
most of the organizations are not very confident and ready to adopt it. This research
paper tackles this issue for organizations in terms of adoptability of the technology
especially the NGO sector in Kenya. In this paper the researcher discusses the
perceived benefits, awareness levels, drivers of adoption as well as barriers to cloud
computing adoption and assess the extent to which this technology has been adopted
in the international NGOs in Kenya.
This study revealed the awareness levels to be overwhelming and further validated
that economical, technical, strategic and functional being the key drivers of adoption.
Lack of clear strategy, lack of ownership and loss of confidentiality were also
endorsed as key barriers to adoption. Majority of the NGOs had more than 71%
computerization levels with a paltry 26% of this having adopted the cloud. Cloud
providers key concerns according to the study include security, the perceived loss of
ownership and fear of confidentiality breach so us to encourage organizations to take
up more of the cloud services on offer. Organizations should also be deliberate to
capture cloud computing in their strategies to motivate adoption.
The intention of this research is to provide information about cloud computing that
will assist those interested non-governmental organizations (NGOs) in this technology
in making well-informed decisions. NGOs must become aware of the predictors that
if adequately examined will indicate successful adoption of cloud computing for
NGOs in Kenya.

▼ Cloud computing is a very popular field at present which is growing very fast and the future of
the field seems really wide. With progressive spotlight on cloud computing as a possible solution
for a flexible, on-demand computing infrastructure for lots of applications, many companies and
unions have started using it. Obviously, cloud computing has been recognized as a model for
supporting infrastructure, platform and software services. Within cloud systems, massive
distributed data center infrastructure, virtualized physical resources, virtualized middleware
platform such as VMware as well as applications are all being provided and consumed as
services. The cloud clients should get good and reliable services from a provider and the provider
should allocate the resources in a proper way so as to render good services to a client. This
brings about the problem of optimization where clients request for more services than they
actually require leading to wastage of the cloud storage resource .This demands for optimization
both on the part of the client and the cloud service provider. This has lead to increased research
in the various techniques that can be used for resource allocation within cloud services. This
research focuses on the analysis of machine learning as a technique that can be used to predict
the cloud storage service request patterns from the clients. The research focuses on a review of
machine learning as a technique that can be used to predict and therefore optimize the user
storage resource demand and usage for the case of cloud computing storage IaaS. Data on cloud
storage resource usage was subjected to experiments using machine learning techniques so as to
determine which give the most accurate prediction. Some of these machine learning techniques
to be reviewed in this research include linear regression, artificial neural networks (ANN),
support vector machines (SVM).From the experiments done in this research, it can be concluded
that the use of support vector machine algorithm (SVM) proves to be the best algorithm for
learning the storage resource usage patterns and predicting their future usage so as to enable
better resource budgeting.

▼ The growth in mobile devices and applications has leveraged the emergence of mobile cloud computing, which allows the access to services at any place and extends mobile computing. Usually, the current mobile network consists of a restricting factor in supporting such access because, from a global perspective, cloud servers are distant from most mobile users, which introduces signi cant latency and results in considerably delays on applications in mobile devices. On the other hand, Cloudlet are usually on the edge of Mobile Networks and can serve content to mobile users with high availability and high performance. This thesis reviews both the traditional mobile cloud computing and the Cloudlet architecture. A taxonomy on the Cloudlet architecture is introduced and three related technologies are discussed. Based on the user needs in this environment, personal model which is used to predict individual behaviour and group model which considers caching popular data for several users are proposed. Making use of these two models and the Cloudlet architecture, two data access schemes are designed based on model distribution
and data pre-distribution. We have conducted experiments and analysis for both the
models and data access schemes. For the models, model efficiency and comparisons among different technologies are analysed. Simulation results for the data access schemes show that the proposed schemes outperform the existing method from both battery consumption and performance aspects.

Falar de mudanças na área da informática é como falar de frio no Pólo Norte, ou
seja, não estamos perante nada de novo. Existem contudo alterações que
representam uma descontinuidade com o passado, e esse tipo de alterações são já
bem menos frequentes. O Cloud Computing insere-se nesta lista bastante mais
restrita. Estamos a falar de um novo paradigma da computação que começou a dar
os primeiros passos entre o final do século passado e o início deste, aquando da
disponibilização dos primeiros serviços online (nomeadamente o Gmail, Hotmail,
Salesforce CRM, entre outros) e que, neste momento, impulsionado pela actual
conjuntura económica e por fenómenos associados à deslocalização da força de
trabalho, despertou o interesse do meio empresarial. A este nível, o cloud
computing representa uma alteração radical relativamente à estruturação das TI e
à forma como estas passam a suportar os sistemas de informação das
organizações, e também à forma como as organizações pensam os seus
investimentos em TI. É importante compreender que essas alterações não se
confinam apenas à esfera tecnológica. Na verdade, elas são bem mais abrangentes
na medida em que podem provocar alterações ao próprio modelo de negócio das
organizações. Este é aliás um dos aspectos a reter, devemos olhar para o Cloud
Computing mais como um modelo de negócio que faz uso de um conjunto de
tecnologias existentes, do que propriamente uma nova tecnologia.
Esta dissertação tem como objectivo realizar uma análise detalhada acerca do
Cloud Computing apresentando o conceito, as camadas, os modelos, as plataformas
existentes e respectivos fornecedores. Para além desses aspectos, pretende-se
analisar a situação do Cloud Computing em Portugal, avaliando o seu grau de
maturidade.
Como componente prática desta dissertação, será realizada a migração de uma
aplicação Web para o formato cloud, utilizando para o efeito a plataforma da
Microsoft, Windows Azure. Essa migração será realizada com o intuito de
identificar eventuais dificuldades ocorridas nesse processo. Adicionalmente será
realizada uma análise de performance face a um modelo de alojamento tradicional.
Speaking of change in computing is like talking of cold at the North Pole, that is, we
are not faced with anything new. However, there are changes that represent a
discontinuity with the past, and such changes are far less frequent. Cloud
Computing is part of this much more restricted list. We are talking about a new
computing paradigm that began to take its first steps towards the end of the last
century and the beginning of this one, when the first services became available
online (namely Gmail, Hotmail, Salesforce CRM, among others) and which at the
moment, driven by current economic phase with the phenomena associated with
the relocation of the workforce, awakened the interest of the business world. At
this level, Cloud Computing represents a radical change on…

▼ Cloud computing technology has been emerging and spreading at a great pace due to its service oriented architecture, elasticity, cost-effectiveness, etc. Many organizations are using Infrastructure-as-a-Service (IaaS) public Clouds for data migration away from traditional IT Infrastructure but there are a few fields such as finance, hospitals, military and others that are reluctant to use public Clouds due to perceived security vulnerability. Enterprises in such fields feel more vulnerable to security breaches and feel secure using in-house IT infrastructure. The introduction of private Clouds is a solution for these businesses.
Private Clouds have been substituted for the traditional IT Infrastructure due to its flexible ``pay-as-you-go" model within an organization by departments and enhanced privacy relative to public Clouds in the form of administration control and supervision.
Goal of my thesis is to build and evaluate a private
Cloud that can provide virtual machines (VMs) as a service and applications as a service. To achieve this goal, in my thesis, I have built and evaluated a service oriented IaaS model of private
Cloud. I have used off-the-shelf servers and open-source software for this purpose. I have proposed a new replication strategy using an Openstack component called Cinder. My experiments show that efficient VM failure recovery on the basis of ``preparation delay" time can be achieved using my strategy. I have studied a real-world application of option pricing from the finance market and have used that application for the purpose of testing my private
Cloud for compute workload and accuracy of the pricing results. Later, I have compared performance between
Cloud VMs and standalone servers. The performance of
Cloud VM is found to be better to standalone servers as long as the number of virtual CPUs (vCPUs) are limited to single node.
Stratus clouds are groups of small clouds that collectively give a spectacular sight in the sky. The private
Cloud I have built uses multiple small modules to achieve the stated goal and hence I named my private
Cloud ``Stratus". This Stratus private
Cloud is now ready for deploying applications, and for providing VMs on-demand.

▼ Cloud service discovery is a new challenge which requires a dedicated framework in order to approach it. Over the past few years, several methods and frameworks have been developed for cloud service discovery but they are mostly designed for all cloud computing models in general which are not optimal. The three cloud computing models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS), each computing model has its own set of resources. Having one single discovery framework for all three is not very efficient and the implementation of such a framework is complex with lots of overhead.
The existing frameworks for cloud service discovery are mostly semantic-based and there are a few syntax-based frameworks that are using the filter by Attribute method as their solution. This research proposes a cloud service discovery framework focusing on IaaS and PaaS cloud computing models. Our framework is using a syntax-based query engine at its core and uses Extensible Markup Language (XML) for storing cloud service information. We eventually test the framework from the user point of view with IaaS and PaaS cloud services from real cloud service providers.
Such a framework could be a good solution for IaaS and PaaS since it is accurate enough for service discovery and easy to update.

▼ Caractériser et simuler les interactions entre les
eaux de surface et souterraines s’avère être un enjeu de plus en
plus important afin de garantir une eau de qualité pour des puits
de pompage situés à proximité d’une rivière. Grâce à la dernière
génération de modèles numériques physiques intégrant les
écoulements de surface et souterrains, il est maintenant possible
de simuler tous les processus physiques gouvernant ces
interactions. Cependant, les résultats de ces modèles sont souvent
peu satisfaisants. Plusieurs études suggèrent que l’utilisation des
charges hydrauliques et des débits de la rivière n’est pas
suffisante pour décrire et contraindre ces processus complexes. Une
revue bibliographique de ces différentes études est présentée dans
le chapitre 2. Afin de parvenir à un meilleur calage de ces
modèles, l’utilisation d’autres types d’observations que l’on peut
qualifier de non-conventionnelles doit être envisagée. Ces
observations non-conventionnelles peuvent être par exemple les flux
caractérisant les interactions ou la concentration de solutés. Le
but principal de cette thèse de doctorat est de montrer que
l’utilisation de ces observations non conventionnelles permet non
seulement d’améliorer significativement le calage de ces modèles,
mais également de réduire grandement les incertitudes de leurs
projections. Le chapitre 4 présente le développement
d’une nouvelle méthode utilisant l’accroissement de cernes des
arbres afin de quantifier l’historique de transpiration des arbres
riverains. Les observations non-conventionnelles obtenues grâce à
cette méthode ont ensuite été utilisées pour caler un modèle
HydroGeoSphere couplant les écoulements souterrains et de surface
ainsi que la transpiration des végétaux. Une analyse d’incertitude
a permis de quantifier la réduction de l’incertitude induite par
l’utilisation de ces observations non-conventionnelles.
Le chapitre 5 présente l’utilisation de traceurs naturels afin de
caler un modèle d’écoulements souterrains et de surface. Cette
étude fut réalisée dans le cadre d’un essai de traçage réalisé dans
un champ de captage situé en Suisse. Après avoir évalué le temps de
résidence de l’eau en utilisant les concentrations en argon-37, une
analyse du mélange entre les eaux récemment infiltrées et les eaux
plus vieilles a été réalisée en analysant les températures
d’infiltration des gaz rares. Ces deux informations qui permettent
de décrire les interactions entre la rivière et l’aquifère furent
utilisées en plus des observations conventionnelles pour caler et
contraindre le modèle de ce champ de captage. Les résultats obtenus
montrent clairement une amélioration des capacités prédictives du
modèle ainsi qu’une diminution de ses incertitudes. Le
chapitre 3 décrit une nouvelle méthode utilisant la méthode de
Monte-Carlos afin d’identifier des zones non saturées entre le lit
d’une rivière et d’un aquifère tous deux aux propriétés
hétérogènes. Finalement, le chapitre6 présente une nouvelle
approche de simulation utilisant HydroGeoSphere, le filtre de
Kalman…

▼ Online hosed services are what is referred to as Cloud Computing. Access to these services is via
the internet. h shifts the traditional IT resource ownership model to renting. Thus, high cost of
infrastructure cannot limit the less privileged from experiencing the benefits that this new
paradigm brings. Therefore, c loud computing provides flexible services to cloud user in the form
o f software, platform and infrastructure as services. The goal behind cloud computing is to provide
computing resources on-demand to cloud users efficiently, through making data centers as friendly
to the environment as possible, by reducing data center energy consumption and carbon emissions.
With the massive growth of high performance computational services and applications, huge
investment is required to build large scale data centers with thousands o f centers and computing
model. Large scale data centers consume enormous amount s of electrical energy. The
computational intensity involved in data center is likely to dramatically increase the difference
between the amount of energy required for peak periods and of T-peak periods in a cloud
computing data center. In addition to the overwhelming operational cost, the overheating caused
by high power consumption will affect the reliability o f machines and hence reduce their lifetime.
There fore, in order to make the best u e of precious electricity resources, it is important to know
how much energy will be required under a certain circumstance in a data center. Consequently,
this dissertation addresses the challenge by developing and energy-efficient model and a
defragmentation algorithm. We further develop an efficient energy usage metric to calculate the
power consumption along with a Load Balancing Virtual Machine Aware Model for improving
delivery of no-demand resource in a cloud-computing environment. The load balancing model
supports the reduction of energy consumption and helps to improve quality of service. An
experimental design was carried out using cloud analyst as a simulation tool. The results obtained
show that the LBVMA model and throttled load balancing algorithm consumed less energy. Also,
the quality or service in terms of response time is much better for data centers that have more
physical machines. but memory configurations at higher frequencies consume more energy.
Additionally, while using the LBVMA model in conjunction with the throttled load balancing
algorithm, less energy is consumed. meaning less carbon is produced by the data center.

▼ Throughout the recent years cloud computing has gained large popularity in the information technology domain. Despite its popularity, there are many organizations that are lacking broader understanding of implementing and utilizing cloud computing for business and operating purpose due to the existing vagueness regarding its cost and security effect associated. It is argued that the main attractiveness of cloud computing for organizations is its cost effectiveness, whilst the major concern relates to the risks for security. Accordingly, more effort has been made in exploring these issues of cloud computing impact. However, little effort has been focused at critically examining the cost risks and security benefits which cloud computing bring to organizations. By using a qualitative method this research examines in detail the essential benefits and risks of cloud computing utilization for organizations in terms of cost and security. Unlike prior studies, it also explores the cost risks and security benefits and shows that they should be taken into consideration by organizations. The findings are based on empirical data collected via interviews with IT professionals. The main cost risk identified is the lack of accurate and sophisticated cost models on the current cloud market. Among the identified security benefits are increased data safety, faster data recovery and transfer, centralization, and improved security software mechanisms and maintenance. Moreover, this research shows several major implications that organizations should keep in mind while utilizing cloud computing and provides some suggestions on how to avoid the cost and security risks identified. At present, reduction of the operational and administrative costs is seen by organizations as the most essential cost benefit. The results show that cloud computing is better for small- and medium-sized organizations and that the hybrid cloud is the most appropriate model for them. Furthermore, the cost and security risks of cloud computing cannot be avoided without resolution of the problem with the lack of accurate cost models, international regulatory frameworks and interoperable security standards on supranational levels.

▼ RESUMEN: El creciente volumen de datos procedentes de distintas fuentes y con distintos formatos hace que la apropiada gestión del ciclo de vida de los datos científicos sea imprescindible para el correcto desarrollo de la ciencia. Durante los últimos años, la Comisión Europea ha estado promoviendo la explotación de resultados, desarrollos y datos por parte de investigadores externos, de modo que se habilita el reuso y aprovechamiento de trabajos apoyados por esta entidad. Varias medidas como el impulso de los Planes de Gestión de Datos, así como la generación de datos “FAIR” (Encontrables, Accesibles, Interoperables y Reusables), están destinadas a garantizar que el esfuerzo invertido en proyectos de investigación sea reaprovechado, de modo que más personas puedan beneficiarse de ello. Esta tesis presenta diferentes diseños, desarrollos, prototipos y servicios en producción basados en “
Cloud Computing” y teniendo en cuenta todo el contexto europeao para asegurar la producción de datos científicos “FAIR”, confirmando que la computación en la nube es apropiada para soportar los retos complejos de la ESFRI LifeWatch.

▼ With
cloud computing emerging in recent years, more and more interest has been sparked from a variety of institutions, organizations and individual users, as they intend to take advantage of web applications to share a huge amount of public and private data and information in a more affordable way and using a reliable IT architecture. In the area of healthcare, medical and health information systems based on
cloud computing are desired, in order to realize the sharing of medical data and health information, coordination of clinical service, along with effective and cost-contained clinical information system infrastructure via the implementation of a distributed and highly-integrated platform. The objective of this study is to discuss the challenges of adopting
cloud computing for collaborative health research information management and provide recommendations to deal with corresponding challenges. More specially, the study will propose a
cloud computing based platform according to recommendations. The platform can be used to bring together health informatics researchers from the different geographical locations to share medical data for research purposes, for instance, data mining used for improving liver cancer early detection and treatment. Finding from a literature review will be discussed to highlight challenges of applying

▼ The use of cloud computing is expanding, and it is becoming the driver for innovation in all companies to serve their customers around the world. A big attention was drawn to the huge energy that was consumed within those datacentres recently neglecting the energy consumption in the rest of the cloud components. Therefore, the energy consumption should be reduced to minimize performance losses, achieve the target battery lifetime, satisfy performance requirements, minimize power consumption, minimize the CO2 emissions, maximize the profit, and maximize resource utilization. Reducing power consumption in the cloud computing datacentres can be achieved by many ways such as managing or utilizing the resources, controlling redundancy, relocating datacentres, improvement of applications or dynamic voltage and frequency scaling. One of the most efficient ways to reduce power is to use a scheduling technique that will find the best task execution order based on the users demands and with the minimum execution time and cloud resources. It is quite a challenge in cloud environment to design an effective and an efficient task scheduling technique which is done based on the user requirements. The scheduling process is not an easy task because within the datacentre there is dissimilar hardware with different capacities and, to improve the resource utilization, an efficient scheduling algorithm must be applied on the incoming tasks to achieve efficient computing resource allocating and power optimization. The scheduler must maintain the balance between the Quality of Service and fairness among the jobs so that the efficiency may be increased. The aim of this project is to propose a novel method for optimizing energy usage in cloud computing environments that satisfy the Quality of Service (QoS) and the regulations of the Service Level Agreement (SLA). Applying a power- and resource-optimised scheduling algorithm will assist to control and improve the process of mapping between the datacentre servers and the incoming tasks and achieve the optimal deployment of the data centre resources to achieve good computing efficiency, network load minimization and reducing the energy consumption in the datacentre. This thesis explores cloud computing energy aware datacentre structures with diverse scheduling heuristics and propose a novel job scheduling technique with sharing and live migration based on file locality (SLM) aiming to maximize efficiency and save power consumed in the datacentre due to bandwidth usage utilization, minimizing the processing time and the system total make span. The propose SLM energy efficient scheduling strategy have four basic algorithms: 1) Job Classifier, 2) SLM job scheduler, 3) Dual fold VM virtualization and 4) VM threshold margins and consolidation. The SLM job classifier worked on categorising the incoming set of user requests to the datacentre in to two different queues based on these requests type and the source file needed to process them. The processing time of each job fluctuate based on the job…

▼ Cloud computing is an emerging technology that is being embraced by more and more
organizations. It has been viewed as a way to increase the capacity or add capabilities
dynamically without investing in new infrastructure, training new personnel, or licensing new
software. A qualitative approach was adopted for this study. In order to gather information on
the subject matter, questionnaires were used. The responses were fed into a cloud readiness
assessment tool and score generated based on the questions. The score ranked the cloud
readiness status as average at 65.4%. This is ranked as average based on the Business
Software Alliance Global Cloud Computing Scorecard. Improving hardware readiness was
identified as an area needing improvement. This can be achieved by obtaining a higher
degree of virtualization and by willing to upgrade the current hardware and software
infrastructure. Connectivity readiness was also identified as needing improvement. The study
also found out that faster broadband connection with redundant capabilities can improve the
score.The assessment computed a potential value of 70.4% that Nairobi County government
could gain from the functionalities and flexibility of the cloud.

▼ Serverless
computing products such as AWS Lambdas and other ``
Cloud Functions'' (CFs) can offer much lower startup latencies than Virtual Machine (VM) instances with lower minimum cost. This has made them an attractive candidate for autoscaling to handle unpredictable spikes in simple, mostly stateless workloads both from a performance and a cost point of view. For complex (stateful, I/O intensive) and latency-critical workloads, however, the efficacy of using CFs in combination with VMs has not been fully explored.
In this paper, we motivate a ``split-service'' application framework that can, for a given job (workload), {\it simultaneously} exploit both infrastructure-as-a-service (VM) and function-as-a-service (CF) products. Specifically, we design and implement a SplitServe-Spark embodiment of our proposal by modifying Apache Spark to use both Amazon VMs and Lambdas. Rather than letting performance degrade following the arrival of such jobs, we show that SplitServe-Spark is able to effectively use CFs to start servicing them immediately while new VMs are being launched, thus reducing the overall execution time. Further, when the new VMs do become available, SplitServe-Spark is able to move ongoing work from Lambdas to the new VMs, if that is deemed desirable from the cost or performance perspectives.
Our experimental evaluation of SplitServe-Spark using four different workloads (K-means clustering, PageRank, TPC-DS, and Pi) shows that SplitServe-Spark improves performance up to 55% for workloads with small to modest amount of shuffling and up to 31% in workloads with large amounts of shuffling, when compared to only VM based autoscaling. Furthermore, SplitServe-Spark along with novel segueing techniques can help us save up to 21% of cost by still giving almost 40% improvement in execution time.

▼ Mobile devices have become ubiquitous and provide ever richer content and functionality. At the same time, applications are also becoming more complex and require ever increasing amount of computational power and energy. With
cloud computing providing unlimited elastic on-demand resources, supporting mobile devices with
cloud allows overcoming limitations of mobile devices. This is generally known as Mobile
Cloud Computing (MCC) and can be achieved through code offloading that selects computationally or data intensive parts of an application, outsources them to more-resourceful spaces and brings back the final results. While code offloading has been widely studied in the past within the context of distributed systems and grid
computing, applying it to current mobile applications requires significant amount of manual changes to existing application codes. An alternative is to outsource the entire application process or the whole virtual machine in which the application is running. This solution assumes running the same code on a more-resourceful system is more efficient, but it is coarse-grained and requires significant amount of data to be transferred. Furthermore, requirements and expectations from mobile applications vary considerably by different users using wide range of mobile devices in various environmental conditions. This diversity in requirements and expectations creates wide range of target offloading goals, ranging from maximizing application performance to minimizing mobile energy consumption. The increased dynamicity and complexity of mobile
cloud applications requires open systems that interact with the environment while addressing application-specific constraints, user expectations and hardware limitations.
Our goal is to facilitate mobile
cloud application development by masking all the complexity of mobile-to-
cloud code offloading without requiring application developers to rewrite their code or perform additional manual work. Our focus is on separating the application logic, to be developed by programmers, from the application component configuration and distribution, to be adjusted transparently and dynamically at run-time.
Our framework is fine-grained, supporting mobile application configuration and distribution at the granularity of individual components; it is flexible, allowing organizations, application developers, or end-users easily adjust target offloading goal or define policy-driven restrictions on offloading budget, execution quality, or privacy and move around of components without modifying the existing application codes; and it is adaptive, addressing the dynamicity in run-time conditions and end-user contexts. It further supports component distribution in a hybrid
cloud environment consisting of multiple public and private
cloud spaces. Finally, it provides a new code offloading model that supports fully parallel program execution, where application components located at mobile device and multiple
cloud spaces are executed independently but concurrently.

▼ Le Cloud Computing est devenu l'un des grands paradigmes de l'informatique et propose de fournir les ressources informatiques sous forme de services accessibles au travers de l'Internet. Ces services sont généralement organisés selon trois types ou niveaux. On parle de modèle SPI pour “Software, Platform, Infrastructure” en anglais. De la même façon que pour les applications ``standard'', les services de Cloud doivent être capables de s'adapter de manière autonome afin de tenir compte de l'évolution de leur environnement. À ce sujet, il existe de nombreux travaux tels que ceux concernant la consolidation de serveur et l'économie d'énergie. Mais ces travaux sont généralement spécifiques à l'un des niveaux et ne tiennent pas compte des autres. Pourtant, comme l'a affirmé Kephart et al. en 2000, même s'il existe des adaptations à priori indépendantes les unes des autres, celles-ci ont un impact sur l'ensemble du système informatique dans lequel elles sont appliquées. De ce fait, une adaptation au niveau infrastructure peut avoir un impact au niveau plate-forme ou au niveau application. L'objectif de cette thèse est de fournir un support pour l'adaptation permettant de gérer celle-ci comme une problématique transverse au différents niveaux afin d'assurer la cohérence et l'efficacité de l'adaptation. Pour cela, nous proposons une abstraction capable de représenter l'ensemble des niveaux et servant de support pour la définition des reconfigurations. Cette abstraction repose sur les techniques de modèle à l'exécution (Model at Runtime en anglais) qui propose de porter les outils utilisés à la conception pour définir, valider et appliquer une nouvelle configuration pendant l'exécution du système lui-même. Afin de montrer l'utilisabilité de cette abstraction, nous présentons trois expérimentations permettant de montrer l'extensibilité et la généricité de notre solution, de montrerque l'impact sur les performances du système est faible, et de montrer que cette abstraction permet de faire de l'adaptation multiniveaux.
Cloud Computing is becoming the new paradigm for information technology to provide resources as Internet-based services. These services are basically categorized according to three layers also called SPI model (Software, Platform, Infrastructure). The same way as ``non-Cloud'' applications, Cloud services must be able to adapt themselves according to the evolution of their environment. There are many works on dynamic adaptation such as server consolidation and green computing but these works are generally specifics to one layer and do not take the others into account. However Kephart et al. have explain in 2000 that even if adaptations are, in theory, independant, they have an impact on the overall system. Consequently, an adaptation at the infrastructure layer can have an impact at the platform or at the application layers.This thesis provides an abstraction to manage adaptation as an orthogonal concern overs Cloud layers. Based on Model atRuntime ([email protected]) techniques which offer to use design tools to build and…

▼ Cloud computing has grown largely over the past three years and is widely popular amongst today's IT landscape. In a comparative study between 250 IT decision makers of UK companies they said, that they already use cloud services for 61% of their systems. Cloud vendors promise "infinite scalability and resources" combined with on-demand access from everywhere. This lets cloud users quickly forget, that there is still a real IT infrastructure behind a cloud. Due to virtualization and multi-tenancy the complexity of these infrastructures is even increased compared to traditional data centers, while it is hidden from the user and outside of his control. This makes management of service provisioning, monitoring, backup, disaster recovery and especially security more complicated. Due to this, and a number of severe security incidents at commercial providers in recent years there is a growing lack of trust in cloud infrastructures. This thesis presents research on cloud security challenges and how they can be addressed by cloud security audits. Security requirements of an Infrastructure as a Service (IaaS) cloud are identified and it is shown how they differ from traditional data centres. To address cloud specific security challenges, a new cloud audit criteria catalogue is developed. Subsequently, a novel cloud security audit system gets developed, which provides a flexible audit architecture for frequently changing cloud infrastructures. It is based on lightweight software agents, which monitor key events in a cloud and trigger specific targeted security audits on demand - on a customer and a cloud provider perspective. To enable these concurrent cloud audits, a Cloud Audit Policy Language is developed and integrated into the audit architecture. Furthermore, to address advanced cloud specific security challenges, an anomaly detection system based on machine learning technology is developed. By creating cloud usage profiles, a continuous evaluation of events - customer specific as well as customer overspanning - helps to detect anomalies within an IaaS cloud. The feasibility of the research is presented as a prototype and its functionality is presented in three demonstrations. Results prove, that the developed cloud audit architecture is able to mitigate cloud specific security challenges.

▼ Cloud computing is a new concept that incorporates many existing technologies, such as virtualization. Virtualization is important for the establishment of
cloud computing. With virtualization,
cloud computing can virtualize the hardware resources into a huge resource pool for users to utilize. This thesis begins with an introduction to how a widely used service model classifies
cloud computing into three layers. From the bottom up, they are IaaS, PaaS, and SaaS. Some service provides are taken as examples for each service model, such as Amazon
Beanstalk and Google App Engine for PaaS; Amazon CloudFormation and Microsoft mCloud for IaaS. Next, we turn our discussion to the hypervisors and the technologies for virtualizing hardware resources, such as CPUs, memory, and devices. Then, storage and network virtualization techniques are discussed. Finally, the conclusions and the future directions of virtualization are drawn.

▼ The focus of this thesis is solving the problem of resource allocation in cloud datacenter using an Infrastructure-as-a-Service (IaaS) cloud model. We have investigated the behavior of IaaS cloud datacenters through detailed analytical and simulation models that model linear, transitional and saturated operation regimes. We have obtained accurate performance metrics such as task blocking probability, total delay, utilization and energy consumption. Our results show that the offered load does not offer complete characterization of datacenter operation; therefore, in our evaluations, we have considered the impact of task arrival rate and task service time separately.
To keep the cloud system in the linear operation regime, we have proposed several dynamic algorithms to control the admission of incoming tasks. In our first solution, task admission is based on task blocking probability and predefined thresholds for task arrival rate. The algorithms in our second solution are based on full rate task acceptance threshold and filtering coefficient. Our results confirm that the proposed task admission mechanisms are capable of maintaining the stability of cloud system under a wide range of input parameter values.
Finally, we have developed resource allocation solutions for mobile clouds in which offloading requests from a mobile device can lead to forking of new tasks in on-demand manner. To address this problem, we have proposed two flexible resource allocation mechanisms with different prioritization: one in which forked tasks are given full priority over newly arrived ones, and another in which a threshold is established to control the priority. Our results demonstrate that threshold-based priority scheme presents better system performance than the full priority scheme. Our proposed solution for clouds with mobile users can be also applied in other clouds which their users’ applications fork new tasks.

▼ One of the recent innovations in providing third-party support for processing needs is
cloud computing. These clouds provide scalable hardware and software resources on demand in exchange for a fee. However, this reliance on third party hardware and software does come with increased security challenges. The vulnerability we chose to analyze was whether the shared physical resources would allow memory remnants to be passed between virtual machine tenants. We analyzed two possible ways for these memory remnants to be transferred to an attacker, through a virtual machine closing and through one losing memory because the hypervisor ordered it to shrink. We examined whether memory would be leaked and how often we could discover memory remnants with different sized tenants. In both cases, we discovered that tenants on a shared physical machine were able to discover valuable data about programs that had closed recently. With this data, an attacker could easily determine what other users on the
cloud were doing. Based on our discovery, we determined that in both cases, there was significant risk of memory being leaked cross-tenant when using a hypervisor. We also analyzed different defenses to remove the possibility of remnants, and came up with a proposed defense to ensure that the problem wouldn’t persist.

▼ The adoption of IT innovations has been a major area of research in information
systems. The determinants of IT innovations are known to vary on the basis of the
nature of the innovation and the context of adoption. While there is substantial
literature on the adoption of various IT innovations based on utility computing, there
is a dearth of empirical literature on cloud computing adoption by business
organizations. Further, a majority of the empirical studies that have investigated cloud
computing adoption by business organizations have done so in the context of
developed countries. Given that cloud computing adoption has been steadily
increasing in Kenya, the current study aims at investigating the determinants and
antecedents of cloud computing adoption and the effect of cloud computing adoption
on firm performance. To this end, the study adapted the socio-cognitive theories of
organizing vision, institutional forces and organizational mindfulness to understand
cloud computing adoption and its effect on firm performance. To achieve the overall
goal of the study, hypotheses were formulated to test the relationship between cloud
computing vision, institutional forces and organizational mindfulness on cloud
computing adoption; between cloud computing adoption and firm performance; and
the interaction effect of organizational mindfulness on all the relationships. The
relationships and the interaction effects were specified in a SEM diagram comprising
of measurement and structural models. A firm level cross sectional survey was
conducted on selected firms within the financial, ICT and manufacturing sectors in
Kenya. Of the 180 firms sampled, 93 completed the questionnaire resulting in a 51.6
percent response rate. The responses were then used to test the study hypotheses.
Exploratory factor analysis was conducted to purify the data and partial least squares
structural equation modeling used to evaluate the reliability and validity of both the
measurement and structural models. The results indicate that institutional forces and
organizational mindfulness have a significant positive relationship with cloud
computing adoption. Cloud computing adoption was found to have a significant
positive relationship with firm performance. The relationship between cloud
computing vision and cloud computing adoption was found to be negative and
insignificant. The results further showed that the interaction effect of organizational
mindfulness on all the relationships was very low and insignificant. These research
findings show that institutional forces and organizational mindfulness plays a leading
role in determining organizations’ adoption of cloud computing. More importantly,
the results indicate that cloud computing adoption significantly improves firm
performance. A major implication of this study is that community discourse on cloud
computing needs to be enhanced to build a cloud computing vision as its effect on
cloud computing adoption was found to be negative and insignificant. The

▼ Mobile cloud computing is the convergence of two computing domains that of mobile and cloud.
Both are promising technologies for the near future. Cloud computing becomes mobile when a
mobile device is used to access the shared pool of computing resources termed as backend while
the mobile forms the front end which acts as an interface for the mobile user who accesses the
resources from the cloud.
The main objective of this study was to get student perception on a web-based resource access
from cloud in order to increase access to learning materials using cloud computing tools. The
research developed and implemented a prototype which enabled resource access in cloud using
mobile devices. This cloud was deployed using openQRM on CentOS 6.2. A survey was
conducted to access the perceived impact on student experiences in accessing study materials
from the cloud and how this can increase the volume and quality of IT support to teaching staff
in the faculty if cloud computing was to be implemented. The study measured the positive
notion on adoption cloud computing architecture in education. Questionnaires and interviews
where used as research tools. Finally future research directions on Mobile Cloud Computing
were discussed.

▼ De hoofdvraag van dit onderzoek is: Wat zien organisaties als de belangrijkste organisatorische en juridische risico's bij het gebruik van cloud computing en hoe gaan zij met deze risico's om?
Zowel op organisatorisch als juridisch gebied is slechts één extra risico genoemd ten opzichte van de literatuur. Hierdoor mag als algemene conclusie worden geconstateerd dat de risico's uit de literatuur nog steeds van toepassing zijn voor alle organisaties binnen alle branches die de overstap naar een cloudomgeving willen maken of hebben gemaakt. Door deze risico's te onderkennen en te classificeren, kunnen grote gevaren worden voorkomen. Tevens zorgen de risico-inventarisatie en classificatie voor een betere onderbouwing bij de besluitvorming om wel of niet gebruik te gaan maken van een cloudomgeving. Daarnaast bespreekt de literatuur slechts een beperkt aantal mitigerende maatregelen. Het betreffen zowel hoog als laag gewaardeerde maatregelen. Waar de literatuur met name spreekt over techniek-gerelateerde maatregelen, geven de respondenten aan ook maatregelen te nemen op het gebied van organisatie-inrichting en contracten. Tevens is in het onderzoek gevraagd naar de risicomethodiek die wordt gehanteerd. Hieruit komt geen eenduidig antwoord, waardoor hier geen conclusies uit getrokken kunnen worden.

▼ Infrastructure-as-a-Service (IaaS) clouds provide computation and storage services to enterprises and individuals with increased elasticity and low cost.
Cloud customers rent resources in the form of virtual machines (VMs). However, these VMs may face various security threats.
This dissertation proposes a new architectural framework, CloudMonatt, to detect and mitigate potential security threats targeting customers’ VMs in
cloud computing. CloudMonatt monitors the security health of VMs and attests to customers if they are getting their desired security. It takes actions to mitigate the potential threats that can compromise the security properties requested. We design
cloud management and security services, and define new hardware-software modules in
cloud servers to provide the underlying measurements. We define secure communications protocols to guarantee that the monitoring service takes place in an unforgeable way.
To demonstrate how CloudMonatt can enhance the VMs’ security, we consider a variety of threats and their defenses that can be integrated in CloudMonatt. We first consider threats on resource availability. We design a set of memory Denial-of-Service (DoS) attacks: an attacker VM can abuse the shared memory resources to significantly degrade a victim VM’s performance. Then we statistically monitor VMs’ resource consumption behaviors to detect these attacks, and use resource throttling to mitigate the availability threats.
Next, we consider subtle attacks on confidentiality, specifically cache side-channel attacks. An attacker VM can exploit a shared CPU cache to steal information from the victim VM. We collect VMs’ micro-architectural behaviors and use a combination of signature and anomaly detection techniques to identify the existence of various side-channel attacks. We use targeted VM migration to eliminate these confidentiality threats.
Then, we consider attacks on system integrity within a VM. We show how to protect a VM’s system integrity from malware, using Virtual Machine Introspection (VMI) to passively collect information for malware detection and also actively change the VM’s execution paths to defeat the potential malware.
In summary, CloudMonatt is a general-purpose architecture for providing VM security monitoring and protection to
cloud customers. We hope CloudMonatt can be a foundation for future work on protecting VMs’ security health in
cloud computing.
