SOA Solves Business Problems
Service Oriented Architecture (SOA) is gaining momentum. Analysts hype it up endlessly, vendors insist their products support it and pundits write about it, lecture on it, and even make a decent living consulting around it. But, for all this attention, what is SOA and does the infrastructure exist now to build one?
Perhaps it is easier to declare what SOA is not; SOA is not about technology. Rather, it is a style of designing systems so that IT is more responsive to the continually changing demands of business. This goal isn’t new; it is as old as an abacuses and slide rules. What makes SOA revolutionary is the underlying acknowledgement that IT follows business and that business is its fundamental reason for being. That SOA is not a technology is the critical insight. CORBA was a technology. Integration brokers are a technology. Enterprise Service Buses (ESBs) are—perhaps unfortunately—becoming defined by technology. SOA, in contrast, is an approach, a philosophy, and ultimately, a goal.
