The ancient divide between business and IT has been the subject of debate for a long time. In the last few years the predominant answer has become Service Oriented Architecture (SOA), the architectural style that puts welldefined functional components, services, at the centre of business-ICT alignment. Development of SOA is often primarily understood as a program of introducing web services, i.e., technical components that use a set of web-based standards.
However, SOA is much more effective as a mindset and a practice than as a technique only. It offers an integral approach to the efficient, integrated development of ICT services that support flexible cross-domain processes. As a system integrator, Everett practices SOA as a means to an end. In this paper we want to share our experience in using SOA as an approach that supports effective business-ICT communication as well as agile implementation of integrated solutions.
This white paper starts off with discussing the major trends that fuel SOA as an approach that strengthens communication and planning, in order to achieve business-ICT alignment. It goes on to highlight the architecture and roadmap of the middleware platform that is typically needed to facilitate an effective and comprehensive SOA approach. Finally, it answers commonly asked questions about SOA and the technologies used to support it. We hope this paper helps the reader, whether an IT or business manager, a program manager or architect, to apply the service orientation for effectively bringing together people and services, and realise an ICT environment that can really make the difference.
