▼ 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.

▼ On-demand resource provisioning in cloud computing provides tailor-made resource packages to meet users' demands. Public clouds nowadays provide more and more elaborated types of VMs, but have yet to offer flexible dynamic VM assembly, due to the lack of a mature mechanism for pricing tailor-made VMs on the spot. To fulfill this research gap, this thesis investigates dynamic cloud resource provisioning and pricing in various problem settings. We first study the offline setting of VM provisioning and pricing in geo-distributed cloud data centers via a one-time auction that achieves (i) truthfulness in expectation, (ii) polynomial running time in expectation, and (iii) (1-ε)-optimal social welfare in expectation, where ε can be arbitrarily close to 0. Our proposed mechanism applies the perturbation-based scheme for VM allocation and prices the customized VMs using a randomized VCG payment. The computation efficiency is proved by a novel application of smoothed analysis. Next, we target a more realistic case of online VM auction design, where: (i) cloud users bid for resources into the future to assemble customized VMs with desired occupation durations; (ii) the cloud provider dynamically packs multiple types of resources on heterogeneous servers; (iii) the operational costs of servers are considered; (iv) both social welfare and the cloud provider's net profit are to be maximized. We propose posted-price mechanisms based on an online primal-dual optimization framework for both VM allocation and payment calculation; and a randomized reduction algorithm to convert the social welfare maximizing auctions to ones that provide a maximal expected profit for the provider. Our proposed online auctions achieve truthfulness, polynomial time, and good competitive ratios. We further extend the online model to dynamic VM scaling, where customers can repeatedly bid for increasing VM resources in scale-up or scale-out option while the cloud provider has to allocate and price the incremental resources on the go. We identify that the offline optimization program with time-coupling bids is non-standard, with a submodular objective function and non-linear constraints. Thus existing primal-dual frameworks are not applicable. Surprisingly, through novel competitive analysis based on submodularity of the offline objective, we prove that a similar posted-price mechanism proposed for the previous scenario achieves a good competitive ratio for the scaling model. We also investigate the online VM auction in a stochastic model where bid arrivals are independently and identically distributed from an unknown distribution. Via a new application of learning-based online primal-dual framework and careful analysis using probability theory, we achieve a (1-O(ε))-competitive ratio. In addition, we also address cost minimization problems in two typical network service provisioning systems, Network Function Virtualization system and cloud Content Delivery Network. We leverage online learning theory and randomized… Advisors/Committee Members: Wu, C, Lau, FCM.

▼ More and more clouds with diversified properties have been built. Many of them span multiple geographical locations over the globe, imposing time-varying costs on and offering different service proximities to users. Clouds could be private or public, requiring different levels of administration effort and providing different levels of freedom to control. Hybrid clouds, which blend together multiple public and private clouds, possess properties of both types. Based on these diversified properties, multiple clouds have the potential to provide services with higher scalability, lower operational cost and better QoS. To exploit this potential, I examine the means of deploying services on multiple clouds, that can maximize utility in dynamic environments. Firstly, I consider the migration of an important representative application, content distribution services, to geo-distributed hybrid clouds. I model the problem of joint content data migration and request dispatching as a unified optimization framework, and then design a dynamic control algorithm to solve it. The algorithm bounds the response times within the preset QoS target, and guarantees that the overall cost is within a small constant gap from the optimum that can be achieved by a T-slot look ahead mechanism with known future information. Secondly, I study the problem of efficient scheduling for disparate MapReduce workloads on hybrid clouds. I build a fine-grained and tractable model to characterize the scheduling of heterogeneous MapReduce workloads. An online algorithm is proposed for joint task admission control for the private cloud, task outsourcing to the public cloud, and VM allocation to execute the admitted tasks on the private cloud, such that the time-averaged task outsourcing cost is minimized over the long run. The online algorithm features preemptive scheduling of the tasks, where a task executed partially on the on-premise infrastructure can be paused and scheduled to run later. It also achieves such desirable properties as meeting a pre-set task admission ratio and bounding the worst-case task completion time. Thirdly, I consider a cloud computing resource market where a broker is employed that pools the spare resources of multiple private clouds and leases them to serve external users' jobs. I model the interaction between the broker and the private clouds as a two-stage Stackelberg game. As the leader in the game, the broker decides on the pricing for renting VMs from each private cloud. As a follower, each private cloud responds with the number of VMs that it is willing to lease. Combining all this with Lyapunov optimization theory, I design online algorithms for the broker to set the prices and schedule the jobs on the private clouds, and for each private cloud to decide the numbers of VMs to lease. The broker achieves a time-averaged profit that is close to the offline optimum with complete information on future job arrivals and resource availability, while each private cloud earns the best that it can.

▼ 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.

▼ 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.

▼ 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. Advisors/Committee Members: Thulasiram, Ruppa K.

▼ 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.

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…

▼ 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… Advisors/Committee Members: Philip (Dir.), Daniel (Codir.).

▼ 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.

Cloud computing becomes popular nowadays. It allows applications to use the enormous resources in the clouds. With the combination of mobile computing, mobile cloud computing is evolved. With the use of clouds, mobile applications can offload tasks to clouds in client-server model. For cloud computing, migration is an important function for supporting elasticity. Lightweight and portable task migration support allows better resource utilization and data access locality, which are essentials for the success of cloud computing. Various migration techniques are available, such as process migration, thread migration, and virtual machine live migration. However, for these existing migration techniques, migrations are too coarse-grained and costly, and this offsets the benefits from migration. Besides, the migration path is monotonic, and mobile and clouds resources cannot be utilized. In this study, we propose a new computation migration technique called stack-on-demand (SOD). This technique is based on the stack structure of tasks. Computation migration is carried out by exporting parts of the execution state to achieve lightweight and flexible migration. Compared to traditional task migration techniques, SOD allows lightweight computation migration. It allows dynamic execution flows in a multi-domain workflow style. With its lightweight feature, tasks of a large process can be migrated from clouds to small-capacity devices, such as iPhone, in order to use the unique resources, such as photos, found in the devices. In order to support its lightweight feature, various techniques have been introduced. To allow efficient access to remote objects in task migration, we propose an object faulting technique for efficient detection of remote objects. This technique avoids the checking of object status. To allow portable, lightweight application-level migration, asynchronous migration technique and twin method hierarchy instrumentation technique are proposed. This allows lightweight task migration from mobile device to cloud nodes, and vice versa. We implement the SOD concept as a middleware in a mobile cloud environment to allow transparent execution migration of Java programs. It has shown that SOD migration cost is pretty low, comparing to several existing migration mechanisms. We also conduct experiments with mobile devices to demonstrate the elasticity of SOD, in which server-side heavyweight processes can run adaptively on mobile devices to use the unique resources in the devices. On the other hand, mobile devices can seamlessly offload tasks to the cloud nodes to use the cloud resources. In addition, the system has incorporated a restorable communication layer, and this allows parallel programs to communicate properly with SOD migration.

▼ 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.
