SOA?
It stands for service-oriented architecture. Sometimes people talk about SOAs, even pronouncing it as a word.
Oh great, another alphabet soup acronym to confuse us all. Give me the 35,000ft view. And why should I care?
SOA actually does what it says on the tin. It's an IT architecture based around common platforms, protocols and reusable code. It can be used to support and connect services and business processes across an enterprise.
Eh? Come again, in English this time please...
SOA is essentially a collection of loosely coupled functions across the IT infrastructure - internal and external - that communicate with each other to provide a particular service or business process.
