# Clustering MDM Servers

Clustering is the process of grouping together a set of similar physical systems in order to ensure a level of operational continuity and minimize the risk of unplanned downtime, in particular by taking advantage of load balancing and failover features.

This section provides a high-level view of how to set up such a cluster of MDM Servers for Talend MDM and some information on how failover is handled in a cluster of MDM Servers.

Information noteNote: Switching from the cluster mode to the standalone mode is not supported.
