load balancing
when u want to improve the response time for the requests from number of users, u create server clusters and have a load balancer for the cluster which will route the user requests to the specific server which is not very busy or having less number of users to process.
fail over
when some of the servers in a cluster crashes the request that is being processed by these servers has to be shifted to the running servers. this is fail over
