Glossary of Terms: Geoclustering

Definition: Geoclustering is the practice of geographically separating high availability cluster nodes for disaster recovery protection.

In a high availability cluster, important applications are run on a primary server node that is connected to one or more secondary nodes in a cluster. If application operation fails on the primary node, cluster software orchestrates failover of the application operation to the secondary node (s). If the primary and secondary nodes are located in the same geographical location, any risks to that location (eg. fire, flood, natural disaster) threatens the entire cluster.

By locating cluster nodes in multiple different physical locations, a geocluster enables application operation to continue through local downtime incidents and natural disasters.
