tion Controller and one of the means for the implementation of the Process Cent-
ralization SOA pattern.
So, why would we step aside from the Process Centralization pattern based on a very
comfortable and easy-to-use BPEL and then try to decentralize the processes using an ag-
nostic controller? The following practical example based on a counterfeit, yet quite real-
istic, telecommunication primer will demonstrate the reasons for this approach. Jumping
ahead a little, we would like to substantiate that we are not actually breaking the concept
of the Process Centralization pattern with the implementation of an agnostic controller, as
we are enforcing the process of centralizing composition's rules. Secondly, we are not go-
ing to abandon the idea of using BPEL as the Orchestration language/engine or reinvent
BPEL's syntax. Instead, we will use SOA Suite tools (11 g PS6) in this example; since
SOA patterns have very generic solution approaches, you can roll it up on any other plat-
form.
