Create Failover Plan that will Work when you Need - Part 1
Failover is very important for all IT Pro and is High Importance Project that must have been complete and do periodical checks that works without problems. What is Failover? Maybe all knows what is mean but i would like to repeat again. A general term that i found in Wikipedia is <<In computing, failover is switching to a redundant or standby computer server, system, hardware component or network upon the failure or abnormal termination of the previously active application, server, system, hardware component, or network. Failover and switchover are essentially the same operation, except that failover is automatic and usually operates without warning, while switchover requires human intervention.>>
