Clustering
 
Clustering support for connector listeners
Clustering extends the reliability, availability, and scalability of Integration Server and accomplishes this by providing the infrastructure and tools to use multiple Integration Servers as if they were a single virtual server.
CloudStreams supports the use of clustering by either distributing the processing load for streaming API events across Integration Server instances or limiting the processing to a single Integration Server node, while guaranteeing processing in each mode exactly once.
Apart from the infrastructure requirements enforced by Integration Server to operate in a clustered mode, CloudStreams leverages the distributed cache, which stores data in a Terracotta Server Array to coordinate processing of events between different Integration Server instances. See the webMethods Integration Server Clustering Guide for more information on clustering.
