Overheard: SOA explained

“This article presents a simple, technology-agnostic approach to designing and evolving SOAs. You will not see acronyms such as WSDL, SOAP, or REST, and I promise not to use technical terms like “orchestration,” “realization,” and “governance.”’ Dan North, A Low-Tech Approach to Understanding SOA

SOA stand for “service oriented architecture.” It sounds scary, but it’s not. It’s really just one computer program talking to another — and each of the programs is called a service. Dan North does a great job explaining it.
