Abstract

As advancements in grid computing continue to support a variety of parallel and distributed systems, the issue of large-scale application scheduling is becoming a key concern. In particular, a class of quality-sensitive applications that requires to fulfil some quality requirements in order to satisfy the user needs. There is a growing need to support these applications as they perform unacceptably if platform resources are scarce or if the deployment is not carefully configured and tuned for the anticipated load. In this paper, we present the notion of application service planning where the application is a composition of service components representing their corresponding functionality, and is configured on the grid environment such that all services involved in the composition get sufficient resources to allow them to deliver at least the minimum required quality to be useful for the application. Addressing such a service planning problem, we summarise a quality deviation model and a learning automaton based solution techniques as a flavour of our research.
