SERVICE ORIENTED ARCHITECTURE; THE IMPORTANCE OF SERVICE REGISTRY

Abstract

The challenge to manage the alignment of business and IT development have struggled with poor results, it is essential to bridging the gap between line of business and IT. Spaghetti structure are a well known phenomena in information systems development, this appears when several systems are integrated with point-to-point solutions. The architectural development from client-server architecture and network centric architecture are now moving toward service oriented architecture (SOA). Lack of control could eventually lead to another level of spaghetti structure. Especially in a global world characterized by inter-organizational and interconnected IT and business environments driven by unpredictable customer behavior. Today the aim for management is not only to improve efficiency but also to improve business effectiveness and to manage organizations and customers behaviors more strategically. Our objective is to devise and illustrate the importance of controlling, survey and manage services in service oriented architectures. Furthermore, to increase the knowledge of people engaged in IT and business development regarding service oriented architecture and the concept service registry. The scientific approach was semi structured interviews with a number of respondents, for the thesis, relevant positions in the organization. The implication provides identified key success factors for comprehension of services in SOA and managing balance of dependencies in changing information environments characterized by SOA. We claim that we have created a foundation for an expanded meaningfulness of SOA service, which will lead to higher awareness on improved overview, governance and mutual understanding of SOA services.
