High Availability and Redundancy
Linux Magazine tells us about high availability and redundancy in: Highly-Affordable High Availability, Linux Virtual Server Clusters, and Data Redundancy By DRBD.
"Although high-availability means different things to different people, here it refers to highly-available clusters. An HA cluster is a set of servers that work together to provide a set of services. In an HA cluster, services don't belong to any one server in the cluster, but to the cluster as a whole. If one server fails, its services are provided quickly and automatically by another server."
