SLA-Oriented Resource Provisioning for Cloud Computing: Challenges, Architecture, and Solutions

Cloud computing systems promise to offer subscription-oriented, enterprise-quality computing services to users worldwide. With the increased demand for delivering services to a large number of users, they need to offer differentiated services to users and meet their quality expectations. Existing resource management systems in data centers are yet to support Service Level Agreement (SLA)-oriented resource allocation, and thus need to be enhanced to realize cloud computing and utility computing. In addition, no work has been done to collectively incorporate customer-driven service management, computational risk management, and autonomic resource management into a market-based resource management system to target the rapidly changing enterprise requirements of Cloud computing. This paper presents vision, challenges, and architectural elements of SLA-oriented resource management. The proposed architecture supports integration of marketbased provisioning policies and virtualisation technologies for flexible allocation of resources to applications. The performance results obtained from our working prototype system shows the feasibility and effectiveness of SLA-based resource provisioning in Clouds.Comment: 10 pages, 7 figures, Conference Keynote Paper: 2011 IEEE International Conference on Cloud and Service Computing (CSC 2011, IEEE Press, USA), Hong Kong, China, December 12-14, 201

ABC based Double Layer-Triple Encryption Method for Data Security in Cloud

CLOUD computing is a new computing paradigm that is constructed on virtualization, aligned and circulated computing, utility computing, and service oriented architecture. The advantages of cloud computing include decreased charges and capital expenditures, expanded operational efficiencies, scalability, flexibility, immediate time to market, and so on. Distinct service oriented cloud computing forms have been proposed, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and programs as a Service (SaaS). In cloud computing, users have to give up their data to the cloud service provider for storage and business operations, while the cloud service provider is generally a financial enterprise, which will not be completely trusted. That is the main reason behind researchers’ motivation of the work. The proposed method provides better the data storage security with lesser time

Service oriented interactive media (SOIM) engines enabled by optimized resource sharing

In the same way as cloud computing, Software as a Service (SaaS) and Content Centric Networking (CCN) triggered a new class of software architectures fundamentally different from traditional desktop software, service oriented networking (SON) suggests a new class of media engine technologies, which we call Service Oriented Interactive Media (SOIM) engines. This includes a new approach for game engines and more generally interactive media engines for entertainment, training, educational and dashboard applications. Porting traditional game engines and interactive media engines to the cloud without fundamentally changing the architecture, as done frequently, can enable already various advantages of cloud computing for such kinds of applications, for example simple and transparent upgrading of content and unified user experience on all end-user devices. This paper discusses a new architecture for game engines and interactive media engines fundamentally designed for cloud and SON. Main advantages of SOIM engines are significantly higher resource efficiency, leading to a fraction of cloud hosting costs. SOIM engines achieve these benefits by multilayered data sharing, efficiently handling many input and output channels for video, audio, and 3D world synchronization, and smart user session and session slot management. Architecture and results of a prototype implementation of a SOIM engine are discussed

Reseach on Cloud Computing Service Oriented Architecture (雲端運算服務導向架構之研究 楊建民 1 蔡鈞華 2 劉俊宏 3)

With the development of cloud computing infrastructure, how to combine enterprise information services with external cloud computing resources is an important issue important research topic. At present, some major service providers in the market, such as Google, IBM and HP, etc. It strives to promote and provide powerful cloud computing capabilities and a complete application service environment; however, the current cloud computing The overall application and data are placed on an external platform, causing doubts about the transfer of control rights and information security when enterprises introduce cloud computing. consider.. This research adopts Google Cloud Computing Environment, combines Cloud Computing and Service Oriented Architecture to develop a four-dimensional Layered service platform, in which the application interface layer takes advantage of the open platform to reduce the burden of service interface development. center The control layer connects the service provider and the service demander, controls the complete service process, and uses external cloud computing and Resources in the Data Center. The service supply layer combines various application services and data sources, by separating computing and data This method allows service demanders to maintain control over data, so as to solve the doubts about information security when enterprises introduce cloud architecture. consider. The infrastructure layer can be connected to cloud computing resources, and the service architecture and computing proposed by various cloud operators can be used in the future Capability and storage resources, and according to the advantages and characteristics of individual platforms, give full play to the benefits of cloud computing architecture. Finally, this study demonstrates the feasibility and integration of this service platform by developing the application of digital learning community websites The advantages of external cloud computing services, and future research directions

Service Oriented Architecture for Mobile Cloud Computing

abstract: The Open Services Gateway initiative (OSGi) framework is a standard of module system and service platform that implements a complete and dynamic component model. Currently most of OSGi implementations are implemented by Java, which has similarities of Android language. With the emergence of Android operating system, due to the similarities between Java and Android, the integration of module system and service platform from OSGi to Android system attracts more and more attention. How to make OSGi run in Android is a hot topic, further, how to find a mechanism to enable communication between OSGi and Android system is a more advanced area than simply making OSGi running in Android. This paper, which aimed to fulfill SOA (Service Oriented Architecture) and CBA (Component Based Architecture), proposed a solution on integrating Felix OSGi platform with Android system in order to build up Distributed OSGi framework between mobile phones upon XMPP protocol. And in this paper, it not only successfully makes OSGi run on Android, but also invents a mechanism that makes a seamless collaboration between these two platforms.Dissertation/ThesisM.S.

Distributed aspect-oriented service composition for business compliance governance with public service processes

Service-Oriented Architecture (SOA) offers a technical foundation for Enterprise Application Integration and business collaboration through service-based business components. With increasing process outsourcing and cloud computing, enterprises need process-level integration and collaboration (process-oriented) to quickly launch new business processes for new customers and products. However, business processes that cross organisations’ compliance regulation boundaries are still unaddressed. We introduce a distributed aspect-oriented service composition approach, which enables multiple process clients hot-plugging their business compliance models (business rules, fault handling policy, and execution monitor) to BPEL business processes
