Service-oriented architectures (SOAs) have evolved over the past few years out of the original vision of loosely coupled web services replacing constrained, stovepiped applications throughout enterprise IT. Every major enterprise technology vendor today has developed its own SOA strategy, supported by innumerable mid-size companies and start-ups offering specific SOA aspects or entire solutions. This explosive growth in SOA technology is in response to a global demand--IDC estimates that spending on SOA services alone will grow from $8.6 billion to more than $33 billion by 2010.
