Provision of QoS for Grid Enabled Service Oriented Architectures

The advancement of large scale computing (LSC) has been driven not only by the continuous improvement in hardware infrastructures but also by the development of software paradigms including the introduction of Service Oriented Architecture (SOA). Grid computing is one area of LSC that has seen a focus in the attempt to infuse SOA technology to implement grid services. The decomposition of applications into services is the de-facto in implementing SOA with technologies like Web Services, enabling the implementation at the application layer in a distributed system. Thus, enabling interoperability and maintaining application independence from the network infrastructure. However, this requires a more practical definition of compatibility models that interact at the application layer with grid services. To optimise the integration of SOA on the grid, it is important to identify the quality factors associated with the application layer services which can be merged into a framework with application layer specific QoS factors to discover and schedule jobs and services.
