In resource provisioning for datacenters, an important issue is how resources may be allocated to an application such that the service level agreements (SLAs) are met. Resource provisioning is usually guided by intuitive or heuristic expectation of performance and existing user model. Provisioning based on such methodology, however, usually leads to more resources than are actually necessary. W...

Middleware is increasingly used to develop and deploy components in enterprise distributed real-time and embedded (DRE) systems. A key challenge in these systems is devising resource management algorithms that deploy application components properly onto target nodes. To provide an accurate view of system resource utilization, these algorithms need runtime monitoring of resources. Runtime monito...

Protection capacity re-provisioning mitigates the impact of double-link failures by provisioning new capacity for unprotected demands in a network designed to achieve 100% restorability under singlelink failures. We study the performance of re-provisioning in networks under various resource sharing degrees. Intuitively, the lower is the sharability degree of resources the smaller is the number ...

Cloud computing has become an innovative computing paradigm, which aims at providing reliable, customized, Quality of Service (QoS) and guaranteed computing infrastructures for users. Efficient resource provisioning is required in cloud for effective resource utilization. For resource provisioning, cloud provides virtualized computing resources that are dynamically scalable. This property of cl...

With the rapid development of services computing, services expression, registration and assembly have been partially solved. But for the ultimate goal of computing, namely on-demand service, it has not been able to achieve by far, especially active provisioning approach for services resource. Faced with key issue for requirements-dominated services virtualization, active services resource provi...
