I've got a question on an SOA usage scenario, and hopefully this is an appropriate forum...
Suppose I've got a cluster with two services deployed to dedicated nodes, for example 5 nodes handle requests for Service A, and 5 others are dedicated to serving requests for Service B. First of all, I assume it would be possible for Service A to make a call to Service B the same way a cluster-external client would, by creating a session with the head node and obtaining an EPR for the broker, etc. Are there any performance implications or configuration gotcha's of a service within a cluster calling another service within the same cluster? In this example, service A is a business level service called by various cluster-aware clients, but service B is a utility service utilized only by service A. Both services are process intensive and can be executed mainly async, thus the desire to split them across dedicated nodes.
