Abstract

Service-oriented architectures (SOA), mostly based on Web services (W3C), provide an industrial standard for deploying, publishing, discovering, and invoking enterprise’s services. From its emergence, many specialists have predicted that SOA will revolutionize the distributed computing paradigm and it will make various kinds of e-business (e.g., virtual enterprises, inter-enterprise collaboration, and ASP paradigms) a reality. This article examines the service-oriented architectures (SOA) applied to innovative organization schemes such as virtual enterprises (VE) to resolve the enterprise organizational structure integration problem. The evolution of software architectures from traditional to SOA is presented, along with the characteristics, advantages and disadvantages, and problems and difficulties in applying the SOA, while also focusing on the compatibility between SOA and modern organizational structures. The new standard in the service orchestration level BPEL is considered as a language for business process modelling and its impact to the integration problem is examined. New messaging protocols and frameworks such as the enterprise service bus (ESB) or messaging service bus are also examined. The main focus is on the SOA technology trends of modern organizational structures with regards their formation and integration. The comparison between SOA and traditional architectures provides a clear path to their adoption in various cases.
