In literature (blogs, articles, books on Enterprise Architecture...), it seems there is a real (and exclusive) appliance of SOA in EA. If we consider DDD and SOA share common architecture principles but differ on many others, what is the place for DDD in the EA discipline ?
DDD and SOA play well together. Usually service boundaries match with your bounded contexts. You design cross-context communication using SOA and it all works. EA does not go deep into how you develop your "services" inside but DDD helps you there.
