Clustering is mainly to provide Fail-over capability.. i e if one server is goes down automatically the other server which is having the same configuration ie replica of failed server have to serve the application request. This is achieved through the clustering..


2 types of clustering 
vertical clustering
horizontal clustering..
In realtime we use the horizontal clustering.. i e building the replica of servers on different nodes... it provides the fail over capability.
 In Vertical clustering, we will build the replica of servers on one node.. which fails to provide the Fail over capability..
