This reference covers operational and management aspects of Fabric3. Fabric3 is designed to run in a variety of environments and provide application portability between them. In most cases, configuration is consistent across runtimes

The following are brief descriptions of the supported Fabric3 runtimes:

• The Standalone Server: Fabric3 includes a server that can be run in a single VM or in a distributed environment with multiple runtime clusters.

• The Fabric3 Tomcat Runtime: This runtime is hosted in a Tomcat server. The Fabric3 Tomcat Runtime is integrated with Tomcat facilities including JMX and logging. This runtime provides additional services including support for service clustering, JTA transactions, and datasource pooling.

Note Fabric3 may also be embedded in Java EE application servers.
