Dissertação apresentado à Escola Superior de Tecnologia e Gestão do IPL para obtenção do grau de Mestre em Engenharia Informática - Computação Móvel, orientada pelo Doutor Patrício Rodrigues Domingues e pelo Doutor Sílvio Priem Mendes.O entusiasmo criado em torno do paradigma da computação na nuvem leva as instituições a considerar a sua inclusão em novos projetos e em projetos existentes. As empresas necessitam contudo, de conhecer em antemão as especificidades do novo paradigma e determinar se o negócio beneficia com o uso de serviços de cloud-computing. Do mesmo modo, é importante perceber se a nuvem se encontra preparada para o sector empresarial e qual a curva de aprendizagem e esforço implicados na sua adoção. Nesta dissertação, analisaram-se todos estes pontos através de uma das maiores plataformas de cloud-computing, o Microsoft Windows Azure. Para se aferir o esforço seguiu-se uma abordagem prática, na qual se desenvolveu uma aplicação empresarial que posteriormente foi migrada para a nuvem. O custo de uma solução alojada localmente foi comparado ao custo de uma solução na nuvem tendo-se recorrido a dados de servidores reais para dimensionar o serviço. Foi concluído que não existe ganho financeiro para uma instituição se a mudança para o paradigma da computação na nuvem não tiver em vista o aproveitamento de uma das suas características diferenciadoras como por exemplo, o associativismo de custo, a elasticidade ou a rapidez de aprovisionamento. Por outro lado, os resultados mostram uma poupança na ordem dos 40% caso se faça uso da elasticidade da cloud.

Nya moderna plattformar utvecklas med tiden, och redan existerande system flyttar till de nya plattformarna för att utnyttja deras fördelar. I den här studien har vi arbetat med att byta plattform för ett system beståendes av en webapplikation och en mobilapplikation med en gemensam databas av typen Microsoft SQL server 2012. Det som har undersökts är ifall webapplikationen skulle kunna flyttas till Microsofts molnplattform Windows Azure. Samtidigt har vi undersökt ifall det går att överföra design och funktionalitet ifrån mobilapplikationen utvecklad på iOS till plattformen Windows Phone 8. Arbetet med att flytta databasen löstes genom att hitta ett program som på ett strukturerat sätt kunde återskapa databasen på Windows Azure. Detta gjorde vi med programmet Microsoft SQL Server Management Studio. Arbetet med applikationen bestod av att studera designen och funktionaliteten i iOSapplikationen och försöka återskapa den på den nya plattformen. Det program som vi använde oss av var Windows Visual Studio 2012 och dess tilläggsprogram Windows Phone 8 Software Development Kit (SDK). Flytten av kundhanteringssystemet bestod av att lösa paketproblem på Windows Azure samt att publicera kundhanteringssystemet på Windows Azure. Till detta användes Visual Studio 2012 samt Microsoft Web Matrix. Resultatet har blivit en prototyp av den gamla applikationen på plattformen Windows Phone 8 samt en publicering av kundhanteringssystemet och databasen till Windows Azure. Det flyttade systemets olika delar kommer båda åt databasen, men på grund av tidsbrist har inget systemtest kunnat göras. Detta har lett till att vi inte har kunnat hitta och analysera de skillnader som existerade mellan det gamla systemet och det flyttade systemet.New modern platforms are developed with time, and already existing systems migrate to the new latforms to use their advantages. In this project we have worked on changing the platform for a iven system consisting of a Customer Relationship Management system (CRM system) and a mobile application with a shared Microsoft SQL Server 2012 database. What has been evaluated s if it was possible to move the CRM system to the Microsoft cloud platform Windows Azure. Meanwhile, a study was done on the viability to transfer the iOS applications design and functionality to the Windows Phone 8 platform. The task of moving the database was solved by finding a program that, in a structured way, could recreate the database on Windows Azure. This was done with the program Microsoft SQL Server anagement Studio. The work involving the application consisted of studying the design and functionality of the iOSapplication and partially recreate it on the new platform. The program we used was Windows isual Studio 2012 and its extension Windows Phone 8 SDK. The transfer of the CRM system consisted of solving the package issues that created problems on indows Azure and publishing it on a Windows Azure website. For this we used Visual Studio 012 and Microsoft Web Matrix. The result was a prototype of the wanted application and the publishing of the CRM website and the database on Windows Azure. The new system worked together in a functional way, but due to lack of time a system test was not done to see if the new system had the same functionality as the original system.

When selling a service to companies or individuals, it’s important to deliver what you sell. Currently, Softronic provides companies with a platform that provides different types of services. These services create opportunities to efficiently develop government functions in accordance with the Government’s action plan for e-governance. These services are hosted by using the cloud computing platform Microsoft Windows Azure. The services’ functionality is important for both Softronic and their customers’ businesses. To know early whether there is a problem or if there will be problems with the services, Softronic wanted to monitor one of these services with the help of an external monitoring service. The aim of this thesis was to compare three different systems for monitoring cloud-based services, implement the most suitable one and develop an application for Windows 8 where customers can see the status of their message channel inside the service. The monitoring systems tested were chosen and judged according to Softronics needs and monitoring requirements. A monitoring service called New Relic was chosen for implementation. New Relic has support for most of the required features, and for the rest of the features, an application was developed. A Windows 8 application and a website were developed that show information about customers’ message channels, and a web service was developed to supply both of them with the data they need.När man säljer en tjänst till ett företag eller privatpersoner är det viktigt att man levererar det man lovar. I dagsläget tillhandahåller Softronic en plattform med olika tjänster. Dessa tjänster hjälper till att skapa möjligheter för att lättare kunna utveckla myndigheters verksamhet enligt regeringens handlingsplan för e-förvaltning. Dessa tjänser är driftsatta i Microsofts molnplattform, Windows Azure. Att dessa tjänser fungerar är kritiskt för både Softronic och deras kunder. För att kunna, i ett tidigt stadie, få reda på om det är problem med tjänsterna eller om det kommer bli problem med tjänsterna, ville Softronic övervaka en av dessa tjänster med en redan befintlig monitoreringstjänst. Målet med detta examensarbete var att jämföra tre olika system för övervakning av moln-baserade tjänster för att slutligen implementera den bäst passande av de tre samt utveckla en applikation för Windows 8 där kunden kan se status på sin egen meddelandekanal. I arbetet har de valda applikationerna testats och bedömts efter Softronics behov och krav på övervakning. En monitoreringstjänst som heter New Relic valdes för implementation. New Relic har stöd för de flesta av de nödvändiga funktionerna, och för de resterande funktionerna utvecklades en applikation. En Windows 8-applikation och en websida utvecklades för att visualisera kunders meddelandekanaler, och en webbtjänst utvecklades för att förse båda dessa med den information de behöver.

Full textAbstract:
In this study, the cloud platform Windows Azure has been targeted for test implementations of Geographical Information System (GIS) software in the form of map servers and tile caches. The map servers included were GeoServer, MapNik, MapServer and SharpMap, which together with the tile caches, GeoWebCache, MapCache and TileCache, were installed on Windows Azures three different virtual machine roles (Web, Worker and VM). Furthermore, different techniques for scalingapplications and internal role communication are presented, followed by four sets of performance tests. The performance tests attempt to highlight the differences in request times, how the different role sizes handle the load from the incoming requests, how the different role sizes handle many concurrent TCP-connections and how well the incoming requests are load balanced in between the worker roles. The test implementations showed that all map servers and tile caches were successfully installed in Azure, which leads to the conclusion that Windows Azure is suitable for hosting GIS software with similar installation requirements to the previously mentioned software. Four different approaches (Direct mapping, Public Internal Endpoints, Queue and Worker Role Request Broker) are presented showing how Azure allows different methods in order to scale the internal role communication as well as the external client requests. The performance tests provided somewhat inconclusive test results due to hardware limitations in the test setup. This made it difficult to draw concluding parallels between the final results and the expected values. Minor tendencies in performance gain can be seen when scaling the VM size as well as the number of VMs.

Full textAbstract:
Mjukvara i datorer styr många viktiga funktioner i dagens samhälle och används i stor utsträckning för att kommunicera men även för att styra utrustning. För att mjukvara ska fungera tillförlitligt behöver den byggas korrekt och testas utförligt. För att uppnå tillförlitlighet kan en byggserver används för att automatiskt bygga och testa mjukvaran. Den här rapporten beskriver hur en prototyp av ett övervakningssystem för byggservrar skapats. Systemet sköter övervakningen genom en övervakningstjänst som hämtar information från en byggserver av typen CruiseControl.NET [10] och presenterar informationen på en webbportal. Informationen som hämtas ut från byggservern går från en hög abstraktionsnivå ner till minsta detalj som är baserad på loggfiler från bygget, med exempelvis information om kompileringsfel. Utvecklingen av övervakningssystemet har haft fokus på att göra det möjligt att använda molntjänster och på det sättet inte begränsa vart en byggserver finns placerad. En av de molntjänster som använts är Service Bus Relay [27] som hanterar kommunikationen mellan en övervakningstjänst och webbportalen. Webbportalen har utvecklats för att vara responsiv [34] för på så sätt stödja mobila enheter och ge användaren frihet att besöka webbportalen oavsett enhet. Webbportalen använder sig av en databas för att lagra informationen som bland annat möjliggör övervakning av flera byggservrar, och den välutvecklade användarhanteringen. Det har gjorts flera lärdomar, bland annat genom upptäckt av en bugg i Microsofts implementation av meddelandehanteringen i Service Bus Relay.Software in computers control many important functions in today's society and are widely used for communication but also to control equipment. For the software to work reliably it needs to be built correctly and tested extensively. To achieve reliability, a build server can be used to automatically build and test the software. This report describes how a prototype of a monitoring system for the build servers was created. The system will be monitored by a monitoring service that retrieves information from a build server using the CruiseControl.NET [10] software. The information gathered by the monitoring service will be presented on a web portal. The information retrieved from build the server goes from a high level of abstraction down to the smallest detail that is based on the log files from the build server, for example, information about compilation errors. The development of the monitoring system has been focused on making it possible to use cloud services and thus not restrict where a build server is located. One of the cloud services used is the Service Bus Relay [27] that handles the communication between a monitoring service and the web portal. The web portal is developed to be responsive [34] and provide support for mobile devices which give the user the freedom to visit the web portal from whatever device. The web portal uses a database to store information which enables monitoring of multiple build servers. A well-developed user management system is used on the web portal which provides administrators with an effective tool for user management. There have been several lessons learned, including the discovery of a bug in the Microsoft implementation of message handling in the Service Bus Relay.

This thesis deals with developing applications on Windows Phone 7. The application focuses on two main target groups; cyclists and individuals who are confined to wheelchairs. Application offers the possibility of navigating around the city and over difficult terrain, and is divided into two parts - the client side application, and server side application. Development of the server side application will be analyzed in the thesis Development of map application for tracking in cloud - Server side on Windows Azure, by Vojtech Ruzicka. The primary objective of this thesis is to offer new solutions for development on Windows Phone 7, with attention being given to the communication between client and server. The second objective is to provide the public with the free application, which will help cyclists and handicapped individuals to navigate through cities around the world. The primary goal of this thesis will be achieved by identifying any problems that may arise during development, whereby a simplified description of the problem will be formed and a solution provided. Realization of the second goal will be in the use of application by the public, by providing them with an efficient means of increasing their mobility throughout their surroundings.

Full textAbstract:
Cloud computing is emerging as a promising platform for compute and data intensive scientific applications. Thanks to the on-demand elastic provisioning capabilities, cloud computing has instigated curiosity among researchers from a wide range of disciplines. However, even though many vendors have rolled out their commercial cloud infrastructures, the service offerings are usually only best-effort based without any performance guarantees. Utilization of these resources will be questionable if it can not meet the performance expectations of deployed applications. Additionally, the lack of the familiar development tools hamper the productivity of eScience developers to write robust scientific high performance computing (HPC) applications. There are no standard frameworks that are currently supported by any large set of vendors offering cloud computing services. Consequently, the application portability among different cloud platforms for scientific applications is hard. Among all clouds, the emerging Azure cloud from Microsoft in particular remains a challenge for HPC program development both due to lack of its support for traditional parallel programming support such as Message Passing Interface (MPI) and map-reduce and due to its evolving application programming interfaces (APIs). We have designed newer frameworks and runtime environments to help HPC application developers by providing them with easy to use tools similar to those known from traditional parallel and distributed computing environment set- ting, such as MPI, for scientific application development on the Azure cloud platform. It is challenging to create an efficient framework for any cloud platform, including the Windows Azure platform, as they are mostly offered to users as a black-box with a set of application programming interfaces (APIs) to access various service components. The primary contributions of this Ph.D. thesis are (i) creating a generic framework for bag-of-tasks HPC applications to serve as the basic building block for application development on the Azure cloud platform, (ii) creating a set of APIs for HPC application development over the Azure cloud platform, which is similar to message passing interface (MPI) from traditional parallel and distributed setting, and (iii) implementing Crayons using the proposed APIs as the first end-to-end parallel scientific application to parallelize the fundamental GIS operations.

Full textAbstract:
Les thèmes abordés dans ce manuscrit de thèse sont inspirés de problématiques de recherche rencontrées par la société Lokad, qui sont résumées dans le premier chapitre. Le Chapitre 2 est consacré à l'étude d'une méthode non paramétrique de prévision des quantiles d'une série temporelle. Nous démontrons, en particulier, que la technique proposée converge sous des hypothèses minimales. La suite des travaux porte sur des algorithmes de clustering répartis et asynchrones (DALVQ). Ainsi, le Chapitre 3 propose tout d'abord une description mathématique de ces modèles précédent, et se poursuit ensuite par leur étude théorique. Notamment, nous démontrons l'existence d'un consensus asymptotique et la convergence presque sûre de la procédure vers des points critiques de la distortion. Le chapitre suivant propose des réflexions ainsi que des expériences sur les schémas de parallélisation à mettre en place pour une réalisation effective des algorithmes de type DALVQ. Enfin, le cinquième et dernier chapitre présente une implémentation de ces méthodes sur la plate-forme de Cloud Computing Microsoft Windows Azure. Nous y étudions, entre autres thèmes, l'accélération de la convergence de l'algorithme par l'augmentation de ressources parallèles. Nous le comparons ensuite avec la méthode dite de Lloyd, elle aussi répartie et déployée sur Windows AzureThe subjects addressed in this thesis manuscript are inspired from research problems encountered by the company Lokad, which are summarized in the first chapter. Chapter 2 deals with a nonparametric method for forecasting the quantiles of a real-valued time series. In particular, we establish a consistency result for this technique under minimal assumptions. The remainder of the dissertation is devoted to the analysis of distributed asynchronous clustering algorithms (DALVQ). Chapter 3 first proposes a mathematical description of the models and then offers a theoretical analysis, where the existence of an asymptotical consensus and the almost sure convergence towards critical points of the distortion are proved. In the next chapter, we propose a thorough discussion as well as some experiments on parallelization schemes to be implemented for a practical deployment of DALVQ algorithms. Finally, Chapter 5 contains an effective implementation of DALVQ on the Cloud Computing platform Microsoft Windows Azure. We study, among other topics, the speed ups brought by the algorithm with more parallel computing ressources, and we compare this algorithm with the so-called Lloyd's method, which is also distributed and deployed on Windows Azure

Full textAbstract:
Negli ultimi anni si sente sempre più spesso parlare di cloud computing. L'idea di fondo di questo concetto è quella di pagare per il solo effettivo utilizzo di un servizio, disponibile sulla rete, avendo a disposizione la possibilità di poter variare le proprie risorse utilizzabili a seconda delle necessità, che potrebbero essere, per esempio, applicazioni standard oppure spazi di storage per i dati. Quando cominciò a diffondersi l'utilizzo del Web, la rete Internet veniva raffigurata come una nuvola (cloud) in modo tale che si rendesse l'idea di un'entità esterna rispetto alla nostra casa o al nostro posto di lavoro, un qualcosa cioè al di fuori dei luoghi abituali in cui vengono utilizzati i PC. Tale rappresentazione diventa ora utile per poter spiegare il concetto di cloud computing. Infatti, grazie a questa nuova tecnologia, dati e programmi normalmente presenti nei nostri computer potranno ora trovarsi sul cloud.
Molti reparti IT sono costretti a dedicare una parte significativa del loro tempo a progetti di implementazione, manutenzione e upgrade che spesso non danno un vero valore per l'azienda. I team di sviluppo hanno cominciato quindi a rivolgersi a questa nuova tecnologia emergente per poter minimizzare il tempo dedicato ad attività a basso valore aggiunto per potersi concentrare su quelle attività strategiche che possono fare la differenza per un'azienda. Infatti un'infrastruttura come quella cloud computing promette risparmi nei costi amministrativi che raggiungono addirittura il 50% rispetto ad un software standard di tipo client/server.
Questa nuova tecnologia sta dando inizio ad un cambiamento epocale nel mondo dello sviluppo delle applicazioni. Il passaggio che si sta effettuando verso le nuove soluzioni cloud computing consente infatti di creare applicazioni solide in tempi decisamente più brevi e con costi assai inferiori, evitando inoltre tutte le seccature associate a server, soluzioni software singole, aggiornamenti, senza contare il personale necessario a gestire tutto questo. L'obiettivo di questa tesi è quello di mostrare una panoramica della progettazione e dello sviluppo di applicazioni Web nel cloud computing, analizzandone pregi e difetti in relazione alle soluzioni software attuali.
Nel primo capitolo viene mostrato un quadro generale in riferimento al cloud, mettendo in luce le sue caratteristiche fondamentali, esaminando la sua architettura e valutando vantaggi e svantaggi di tale piattaforma. Nel secondo capitolo viene presentata la nuova metodologia di progettazione nel cloud, operando prima di tutto un confronto con lo sviluppo dei software standard e analizzando poi l'impatto che il cloud computing opera sulla progettazione. Nel terzo capitolo si entra nel merito della progettazione e sviluppo di applicazioni SaaS, specificandone le caratteristiche comuni ed elencando le piattaforme di rilievo allo stato dell'arte. Si entrerà inoltre nel merito della piattaforma Windows Azure. Nel quarto capitolo viene analizzato nel particolare lo sviluppo di applicazioni SaaS Multi-Tenant, specificando livelli e caratteristiche, fino a spiegare le architetture metadata-driven. Nel quinto capitolo viene operato un confronto tra due possibili approcci di sviluppo di un software cloud, analizzando nello specifico le loro differenze a livello di requisiti non funzionali. Nel sesto capitolo, infine, viene effettuata una panoramica dei costi di progettazione di un'applicazione cloud.

Full textAbstract:
Cloud computing has been given a great deal of attention during recent years. Almost all the technology market leaders and leading hosting service providers (like IBM, Microsoft and Verizon) have entered into the Cloud market as Cloud Providers. Cloud computing promises to provide highly available, secure, low cost, agile and highly scalable solution to the consumers. Scania is a global company and one of the world’s leading heavy vehicle manufacturers with 35,000+ employees. All the large organizations such as Scania, aim to constantly update themselves with the latest technology in order to meet their business requirements but, these organizations must always be convinced that there is a strong reason(s) to implement new technology. This research provides the method and criteria in relation to initiating Cloud computing. A number of Scania’s specific business requirements that it is possible to map to the Cloud are addressed in this thesis. The methodology of research is split in two parts. Firstly, the identification of business cases at Scania and their requirements with the Cloud and Secondly, the evaluation and comparison of the functionalities and capabilities of different vendors. The accumulated data is then compared and suitable vendors, according to those business requirements are suggested. This thesis also shares the experience of moving on premise applications to the Cloud. These are Scania specific applications which are currently being hosted in-house. The research also addresses the possibilities of portability between the Cloud providers. Although there is no standardization in relation to Cloud computing, some initiatives such as OpenStack are available and its current position and some application and data migration tools are also discussed. The thesis concludes with a general discussion, recommendations in relation to adapting Cloud computing and selecting the Cloud provider. This recommendation applies to every organization including Scania.

Full textAbstract:
With the advent of cloud computing, resizable scalable infrastructures for data processing is now available to everyone. Software platforms and frameworks that support data intensive distributed applications such as Amazon Web Services and Apache Hadoop enable users to the necessary tools and infrastructure to work with thousands of scalable computers and process terabytes of data. However writing scalable applications that are run on top of these distributed frameworks is still a demanding and challenging task. The thesis aimed to advance the core scientific and technological means of managing, analyzing, visualizing, and extracting useful information from large data sets, collectively known as “big data”. The term “big-data” in this thesis refers to large, diverse, complex, longitudinal and/or distributed data sets generated from instruments, sensors, internet transactions, email, social networks, twitter streams, and/or all digital sources available today and in the future. We introduced architectures and concepts for implementing a cloud-based infrastructure for analyzing large volume of semi-structured and unstructured data. We built and evaluated an application prototype for collecting, organizing, processing, visualizing and analyzing data from the retail industry gathered from indoor navigation systems and social networks (Twitter, Facebook etc). Our finding was that developing large scale data analysis platform is often quite complex when there is an expectation that the processed data will grow continuously in future. The architecture varies depend on requirements. If we want to make a data warehouse and analyze the data afterwards (batch processing) the best choices will be Hadoop clusters and Pig or Hive. This architecture has been proven in Facebook and Yahoo for years. On the other hand, if the application involves real-time data analytics then the recommendation will be Hadoop clusters with Storm which has been successfully used in Twitter. After evaluating the developed prototype we introduced a new architecture which will be able to handle large scale batch and real-time data. We also proposed an upgrade of the existing prototype to handle real-time indoor navigation data.

Full textAbstract:
The current proliferation of mobile systems, such as smart phones, PDA and tablets, has led to their adoption as the primary computing platforms for many users. This trend suggests that designers will continue to aim towards the convergence of functionality on a single mobile device. However, this convergence penalizes the mobile system in computational resources such as processor speed, memory consumption, disk capacity, as well as in weight, size, ergonomics and the user’s most important component, battery life. Therefore, this current trend aims towards the efficient and effective use of its hardware and software components. Hence, energy consumption and response time are major concerns when executing complex algorithms on mobile devices because they require significant resources to solve intricate problems.
Current cloud computing environments for performing complex and data intensive computation remotely are likely to be an excellent solution for off-loading computation and data processing from mobile devices restricted by reduced resources. In cloud computing, virtualization enables a logical abstraction of physical components in a scalable manner that can overcome the physical constraint of resources. This optimizes IT infrastructure and makes cloud computing a worthy cost effective solution.
The intent of this thesis is to determine the types of applications that are better suited to be off-loaded to the cloud from mobile devices. To this end, this thesis quantitatively and
qualitatively compares the performance of executing two different kinds of workloads locally on two different mobile devices and remotely on two different cloud computing providers. The results of this thesis are expected to provide valuable insight to developers and architects of mobile applications by providing information on the applications that can be performed remotely in order to save energy and get better response times while remaining transparent to users.

High Performance Computing (HPC) applications are data-intensive scientific software requiring significant CPU and data storage capabilities. Researchers have examined the performance of Amazon Elastic Compute Cloud (EC2) environment across several HPC benchmarks; however, an extensive HPC benchmark study and a comparison between Amazon EC2 and Windows Azure (Microsoft’s cloud computing platform), with metrics such as memory bandwidth, Input/Output (I/O) performance, and communication computational performance, are largely absent. The purpose of this study is to perform an exhaustive HPC benchmark comparison on EC2 and Windows Azure platforms.
We implement existing benchmarks to evaluate and analyze performance of two public clouds spanning both IaaS and PaaS types. We use Amazon EC2 and Windows Azure as platforms for hosting HPC benchmarks with variations such as instance types, number of nodes, hardware and software. This is accomplished by running benchmarks including STREAM, IOR and NPB benchmarks on these platforms on varied number of nodes for small and medium instance types. These benchmarks measure the memory bandwidth, I/O performance, communication and computational performance. Benchmarking cloud platforms provides useful objective measures of their worthiness for HPC applications in addition to assessing their consistency and predictability in supporting them.

Full textAbstract:
Message passing interface (MPI) has been widely used for implementing parallel and distributed applications. The emergence of cloud computing offers a scalable, fault-tolerant, on-demand al-ternative to traditional on-premise clusters. In this thesis, we investigate the possibility of adopt-ing the cloud platform as an alternative to conventional MPI-based solutions. We show that cloud platform can exhibit competitive performance and benefit the users of this platform with its fault-tolerant architecture and on-demand access for a robust solution. Extensive research is done to identify the difficulties of designing and implementing an MPI-like framework for Azure cloud platform. We present the details of the key components required for implementing such a framework along with our experimental results for benchmarking multiple basic operations of MPI standard implemented in the cloud and its practical application in solving well-known large-scale algorithmic problems.

Enterprise could easily configure services from cloud computing with low upfront investments of hardware and equipment. Nevertheless,ENISA (European Network and Information Security Agency) researches on cloud services show that the security concern is the most important point for enterprise adoption of cloud services[26]. To achieve this, risk assessment becomes a main of procedures to improve the trust of cloud services for users. In this paper, we propose an approach to assess the risk associated with applying a cloud service, exemplified by Windows Azure and based on principle of risk assessment from ISO 31010[17]. Our approach could monitor the probability of risk of the related services, and present the quantitative risk in corresponding money loss, which then can be used to support decision making of adoption of the service.
