WebSphere Application Server: A foundation for on demand computing
E.N. Herness, Rob High, J. R. McGee · IBM Systems Journal · 2004
WebSphere® Application Server is the foundation for IBM's middleware software portfolio. It has evolved rapidly from a simple extension for Web servers and a server runtime for business objects to the IBM distributed operating system for mission-critical computing and the leading application server in the industry. WebSphere Application Server plays a central role in the transformation from a distributed operating system to a distributed on demand operating system. This transformation is achieved by forging extensions to the WebSphere Application Server foundation for the grid-computing infrastructure, rich Web-based interaction models, service-oriented architecture, autonomics, business process management, and dynamic provisioning and utility management. This paper describes elements of the WebSphere Application Server architecture and how this architecture provides a foundation for the on demand computing infrastructure and application environment.
