“…The broker should be able also to cache the authorization and authentication (AA) tokens so that the users would be able to use a single AA model/token to access the cloud resources on all the federated infrastructures. Within the FleSSR project, the broker called 'eZeel' developed by EoverI [8] satisfied all these requirements with the added benefit of offering an application programming interface (API) to the developers of the project use cases.…”

Cloud computing has been increasingly adopted by users and providers to promote a flexible, scalable and tailored access to computing resources. Nonetheless, the consolidation of this paradigm has uncovered some of its limitations. Initially devised by corporations with direct control over large amounts of computational resources, cloud computing is now being endorsed by organizations with limited resources or with a more articulated, less direct control over these resources. The challenge for these organizations is to leverage the benefits of cloud computing while dealing with limited and often widely distributed computing resources. This study focuses on the adoption of cloud computing by higher education institutions and addresses two main issues: flexible and on-demand access to a large amount of storage resources, and scalability across a heterogeneous set of cloud infrastructures. The proposed solutions leverage a federated approach to cloud resources in which users access multiple and largely independent cloud infrastructures through a highly customizable broker layer. This approach allows for a uniform authentication and authorization infrastructure, a fine-grained policy specification and the aggregation of accounting and monitoring. Within a loosely coupled federation of cloud infrastructures, users can access vast amount of data without copying them across cloud infrastructures and can scale their resource provisions when the local cloud resources become insufficient.

“…In the model, applications are agnostic to the underlying provider; this means that applications can use the most appropriate cloud resources when they are needed. The Zeel/i framework [17] uses the customised mechanisms of a host provider to configure an environment for a user. The environment is wrapped in a provider-agnostic API which insulates applications from provider APIs (see Figure 1).…”

Increasingly infrastructure providers are supplying the cloud marketplace with storage and on-demand compute resources to host cloud applications. From an application user's point of view, it is desirable to identify the most appropriate set of available resources on which to execute an application. Resource choice can be complex and may involve comparing available hardware specifications, operating systems, value-added services (such as network configuration or data replication) and operating costs (such as hosting cost and data throughput). Providers' cost models often change and new commodity cost models (such as spot pricing) can offer significant savings. In this paper, a software abstraction layer is used to discover the most appropriate infrastructure resources for a given application, by applying a two-phase constraints-based approach to a multi-provider cloud environment. In the first phase, a set of possible infrastructure resources is identified for the application. In the second phase, a suitable heuristic is used to select the most appropriate resources from the initial set. For some applications a cost-based heuristic may be most appropriate; for others a performance-based heuristic may be of greater relevance. A financial services application and a high performance computing application are used to illustrate the execution of the proposed resource discovery mechanism. The experimental results show that the proposed model can dynamically select appropriate resouces for an application's requirements.

Cloud computing is expected to provide powerful and easy-to-use model for application design, development, operation and maintenance. There are mainly two models of cloud: IaaS and PaaS model. In IaaS model, application developer and operator have the biggest flexibility for they can control owned virtual machines and most resources totally, but this model needs high technical skills in application development and operation phase. PaaS model claims easy to development, deployment and maintenance, but all these advantage are based on the specific programming model and application architecture. Migration to PaaS cloud for existing applications usually brings big effort and cost increasing. In this paper, we discuss the advantages and disadvantages of the two models from enterprise class application developer angle. Then present an application lifecycle model in which developers could design, develop and deploy their application or legacy systems without programming limitation and migration effort. The application lifecycle model takes application as the centric concept and supported by a set of cloud platform tools. We discuss the application lifecycle framework defined in this model, and then we discussed the possible supporting cloud architecture.
