15.2. Setting Up SwitchYard in a Clustered Environment

The two fundamental building blocks that are used for setting up SwitchYard in a clustered environment are:

The runtime registry supports a replicated Infinispan cache. Each instance in a cluster points to the same replicated cache. When a node joins a cluster, it immediately has access to all remote service endpoints published in the registry. If a node leaves the cluster due to failure or shutdown, all service endpoint registrations are immediately removed for that node. The registry is not persisted, so manual clean-up and maintenance is not required.

The communication channel is a private intra-cluster protocol used by instances to invoke a remote service. At present, the channel is based on HTTP.
