What is Failover Testing?
Failover Tests verify of redundancy mechanisms while under load. For example, Failover Tests testing determines what will happen if multiple web servers are being used under peak anticipated load, and one of them dies. Does the load balancer react quickly enough? Can the other web servers handle the sudden dumping of extra load? This sort of testing allows technicians to address problems in advance, in the comfort of a testing situation, rather than in the heat of a production outage.
