Service-Oriented Architectures and Middleware

Service-oriented architectures (SOA) are loosely-coupled networks of applications owned and managed by diverse business partners. SOAs are developed using service-oriented computing technology, such as the Web services set of specifications, which is centered on open standards and the pervasiveness of Internet technologies.

Our research aims to contribute to the understanding of (Web) service-oriented architectures and the development of (Web) service-oriented middleware. We explore SOAs and service-oriented middleware for use by both enterprise-scale as well as small-to-medium-size businesses.

Our SOA research focuses on the following areas:

• Web services coordination and transactions (see also the AEM page on Transaction Processing)
• Web services composition and business processes (see, for example, the paper "Composition of Coordinated Web Services")
• Web services quality-of-service and policies (see, for example, the paper "GlueQoS: Middleware to Sweeten Quality-of-Service Policy Interactions")
