If the clusters are identical (means they have similar properties, provide similar services...), then they are homogeneous. Else they are heterogeneous.

Hi Rahul,
i didn't get any meterial for this.i think what sugana explained is correct bcz i read the article as follows.
By default, every server in a BEA WebLogic Server Cluster is homogeneous�hosting all of the same application services. Automatic routing, however, frees your system administrator to partition and dynamically repartition the business processing within the cluster as desired�for example, specializing some servers to handle checking accounts and others to handle savings.

Hi Seenu,
Now I get it.
What the author means is that by deploying the and application and its components to a cluster rather than to individual servers makes it homogenous.
On the other hand if lets say I deploy application 1 to server A and Application 2 to Server B where in servers A and B form a Cluster then this is a hetrogenous deployment.
