Clustering GeoServer

Clustering GeoServer can be requested in order to achieve either an Highly Available set up or in order to achieve more scalability. Regardless of the reason why intend to create a clustered deployment for GeoServer there are a few limitations that must be taken into account and where possible worked around.

In the remaining part of this section we will provide the attendee with information to gain a basic understanding of Clustering then we will dwelve into the various possibilities for clustering GeoServer and GeoWebCache discussing pros and cons of each approach.
