Types of Clusters ?

In Windows we can configure two types of clusters 


1. NLB (network load balancing)  : cluster for balancing load between servers. This cluster will not provide any high availability. Usually preferable at edge servers like web or proxy.



2. Server Cluster: This provides High availability by configuring active-active or active-passive cluster. In 2 node active-passive cluster one node will be active and one node will be stand by. When active server fails the application will FAILOVER to stand by server automatically. When the original server backs we need to FAILBACK the application
