It is possible to run Confluence in a clustered environment instead of on a single server. This means that you can run multiple copies of Confluence in a cluster, so that clients (such as a browser) can connect to any copy and see the same information.

While we have tried to make clustering Confluence as easy and administrator-friendly as possible, it is a major architectural change and requires extra planning for deployment and upgrades. Please consider the information on the Cluster Checklist and then consult Atlassian support before making your final decision.


This page gives an overview and links to further pages with information on installing, configuring and administering a Confluence cluster.

Before Deciding to Run a Confluence Cluster

  1. Read and consider the details on the Cluster Checklist.
  2. Consider the difference between clustering for scalability and clustering for high availability (HA).
  3. Contact Atlassian support for further information and advice.
