Ensuring Resource-Level Quality for Services on Grids

Abstract--Service-Oriented Architectures address the development of distributed and dynamic service-based applications. Due to the dynamics of their environments, services should be selfadaptable in order to maintain agreed resource-level qualities. To support building such services, this work proposes the SelfAdaptable Service Execution Manager (SASEM), responsible for monitoring and controlling the service execution on grid resources in order to prevent SLA violations. SASEM builds on the Dynaco adaptation model and on an enhanced grid monitoring and actuation system, implemented using the XtreemOS grid operating system.
