Abstract

Service Oriented Architecture (SOA) has been one of the most important topics in enterprise application development in the last years. SOA has introduced important changes to the architecture of business applications. The Service Component Architecture and the composite application approach with BPMN, BPEL, ESB, and other important pieces have made applications loosely-coupled and flexible. In the paper we give an overview of the SOA, describe the concepts and SOA building blocks. We elaborate on the value and impact of SOA on information system development and outline the reach of SOA towards information systems, business processes, governance, and organization
