Figure 2-2 A single clustered architecture
Key features of this architecture are:
A single load balanced HTTP Server cluster (HTTP Cluster) that spans two or more
physical nodes.
A single WebShere Portal Server cluster (Portal Cluster) deployed in a single WebSphere
Cell.
The WebShere Portal Server cluster consists of two of more horizontal cluster members
and any number of vertical cluster members per node (resources permitting).
A dedicated stand-alone WebSphere Deployment Manager is responsible for the
management of the entire WebSphere Cell (Cell A).
As the environment only consists of a single WebShere Portal Server cluster, only a single
release database domain is required.
The remaining database domains (communityusr, customizationusr, wmmusr, fdbkusr,
lmdbusr, and jcr) are deployed alongside the release database domain. Note that the JCR
Repository exists in a different database.
The environment also hosts a LDAP directory server (not shown), which is highly
available, for maintaining the registered user base.
