Performance assurance has become an important aspect in grid and cloud computing which provide services over the Internet, and Service Level Agreements (SLA) are frequently contracted between users and the service providers. However, the I/O performance of the storage or data access service is still provided on a best effort basis. Some distributed storage systems implement performance reservation,...
Grid Computing supports the shared and coordinated use of several resources in dynamic Virtual Organizations. In the last few years, it is evolving into a business-innovating technology that is driving commercial adoption. Such a new scenario calls for powerful strategies able to guarantee stringent QoS requirements in order to meet Service Level Agreements (SLAs) between customers and providers....
In order to co-ordinate multiple resource providers in grid environment to meet a common objective, support for negotiation is needed to establish a contract between the user and the resource providers that clearly states the QoS required, restrictions on resource utilization and penalties during violation of the objective. Strength of the negotiation process mainly depends on the selection of resources...
This keynote paper: presents a 21st century vision of computing; identifies various computing paradigms promising to deliver the vision of computing utilities; defines Cloud computing and provides the architecture for creating market-oriented Clouds by leveraging technologies such as VMs; provides thoughts on market-based resource management strategies that encompass both customer-driven service management...
Complex and mission-critical applications require the use of distributed environments, which will allow their execution in a reliable and cost-efficient way. Grid environments made this case feasible by providing heterogeneous resources. Nevertheless, quality of service (QoS) aspects are regarded as fundamental for enabling the execution of business applications in grids. In that frame, we introduce...
Resource-sharing is one of the grid intrinsic properties enabling efficient usage of services by clients from many virtual organizations. In such an environment, the provisioning of quality of service requires mechanisms for the control of the concurrent access to resources and services, as well as protocols for the establishment of service level agreements between users and service providers. Nevertheless,...
