WS‐GAF: a framework for building Grid applications using Web Services

This paper presents the motivation and design decisions for the Web Services Grid Application Framework (WS‐GAF), which is a mapping of Grid architecture requirements onto the Web Services Architecture. The goal for WS‐GAF is to describe a framework for building Grid applications that adheres to the principles of service‐oriented architectures and utilizes existing Web Services technologies. The proposed solution addresses issues including stateful interactions, logical resource naming, metadata, and lifetime management. Copyright

Grid computing using web services technologies

Service-Oriented Architecture (SOA) is the contemporary paradigm of choice for developing scalable, loosely-coupled applications that span organisations. However the architectural paradigm that is SOA is often confused with the implementation technology that is Web Services. In this paper we aim to clarify the fundamental tenets of SOA and their relevance to Internet-scale computing (or Grid computing). We then show how to apply the principles of SOA to building Internet-scale applications using Web Services technologies and how to avoid software pitfalls by adhering to a number of deliberately simple architectural constraints.
