Learn how and when to grow clustered topologies that use IBM® WebSphere® Process Server and WebSphere Enterprise Service Bus. When new BPM and ESB applications are deployed, you may need to expand the initial topology to take advantage of increased IT resources (such as memory) or to isolate applications. This article describes a standard "golden topology" widely used in production deployments, and then examines how to grow the topology from within the cluster, and by adding new clusters. It describes good and bad design patterns, what to consider, and the costs and limitations of each approach. The article also describes how to plan for Service Integration Bus connectivity and desired messaging engine behavior.
