What is cluster? What are the types of Clusters and their advantages?

A.Cluster is set of App servers .
Types:
Horizontal Clustering:
• Here In two different Nodes ( diff blades) you have 2 cluster members where
all the requests gets routed to the cluster members, When ever one blade or
Node crashes then automatically the requests gets routed to the other Node
or Blade.
• Here the advantage is Failover
Vertical Clustering:
• Here In Single Node you have two cluster members where all the requests get
routed to the two cluster members.
• Here the advantage is Performance.
