SOA isn’t response request

I’ve often been told that one of the biggest mistakes people make when implementing a service oriented architecture is that they don’t re-architect their current architecture to become service oriented. I’ve never really understood what they meant by that until I read this article. SOA is not about adding a service based call to expose your current procedure calls as a service - it’s so much more. It’s about enabling ease of change and to create a more agile architecture.

Each of these assumptions exist in a Remote Procedure Call. They are forms of coupling, pure and simple. They fly in the face of SOA. > >

What do you think? Does it make sense in your world?
