OpenCCM DCI Components Î DCIManager = a deployment domain ¾ Provides AssemblyFactory and HomeFinder
Î NodeManager = a virtual host ¾ Provides ComponentInstallation and ServerActivator
Î ComponentServerManager = a component server ¾ Provides ComponentServer
Î ContainerManager = a container ¾ Provides Container
Î AssemblyManager = an assembly deployment controller ¾ Provides Assembly
Î Each component provides other ports for management and supervision purposes
