Follows the Java EE model
–
Consolidates configuration into a single distributable entity
–
Provides Application Isolation & Lifecycle Events
 Leverages WebLogic infrastructure to provide:
–
A Coherence container similar to EJB, JMS and JCA
–
Management through Configuration Wizard, WebLogic
admin console, WLST, JMX, FMWC
–
Deployment of Coherence applications (GARs)
–
Node Manager for lifecycle management
–
Release and install Coherence libraries on the system
classpath (no need to package in your application)
 Coherence remains available “standalone”
