There is always a debate who should drive the SOA initiative in Enterprise. It could be business, architecture team, delivery or Operations team. It benefits all of them in different ways. SOA from different viewpoints looks like
- Business see SOA as a set of business services that are exposed to its clients. It reduces the time to market and costs of building business processes. It increases business agility and simplify the IT.
- Architects see SOA as an architectural approach to build business processes. It is based on well known principles and patterns like loose coupling, separation of concerns, encapsulation etc. It constitutes of provider, consumer and contract.
-Developer see SOA as a set of standards, tools and technologies like Web Services.
-Operational people see SOA as a better contract between Service provider and Service consumer.
In my view, SOA impacts the entire Enterprise and everyone is stakeholder. Unlike earlier concepts of distributed computing in IT, SOA is more near to business people. Hope IT will fulfill the agility and reusability promise this time.
