CloudStreams uses Terracotta to cache the virtual services you deploy to a CloudStreams server. It also uses Terracotta to cache many of the artifacts associated with the virtual services (for example, performance metrics, policies, and consumer applications). When you install CloudStreams on a cluster of Integration Servers, CloudStreams maintains these caches on the Terracotta Server Array.

For more information about CloudStreams system caches, see System Caches Used by the webMethods Product Suite .
