CEP, boosting services in the SOA strategy

CEP, boosting services in the SOA strategy

In this article we are going to talk about one of the most powerful tools, and in my opinion most undervalued, in terms of system integration. Complex event processing, CEP, is an ideal complement and of enormous value in an SOA strategy where, as we know, business...

Service Reusability

  Reusability. Time for one of SOA's best-known principles: reusability. It is certainly one of the most obvious benefits of service orientation. It is surely the easiest to explain and understand. It is often the easiest to take on by those approaching SOA. In fact,...
