What is cluster in websphere application server and how to create the cluster.

                              Cluster
cluster is a logical name and  group of application server act as a single unit to perform the task and provide the  workload balance , high availability , fail over and scalability in Network deployment.

There is two type cluster in websphere application server

1. Horizontal Cluster
2. Vertical Cluster

Horizontal cluster :-    in horizontal cluster all nodes should be  in different physical machine and all nodes are federated with Dmgr cell . in this type of cluster if in case any nodes  hardware has  failed   then request will route to another nodes server to process.






Vertical Cluster - In vertical cluster all configuration exist in the same physical machine or node in this type of clustering there is lot of chance for failure the system but this is the cheap and can be fast monitoring .
