During normal cluster operation, each server is in constant communication
with the other servers in the cluster and performs periodic polling of all
registered resources to detect failure.
Suppose Web Server 1 experiences hardware or software problems and the
users depending on Web Server 1 for Internet access, e-mail, and information
lose their connections. The following figure shows how resources are moved
when Web Server 1 fails.
