Running Confluence Data Center on a single node

Data Center allows you to run Confluence in a cluster with multiple nodes, or on a single server (also known as non-clustered, or standalone Data Center).

This page outlines the architecture and requirements of a non-clustered Confluence Data Center deployment, as well as some of the benefits and considerations.


The deployment architecture of a non-clustered Data Center deployment is the same as a Server installation. Here’s what a typical setup looks like:

As you can see, Confluence Data Center deployed on a single node looks just as a Server installation, and consists of:

  • Confluence Data Center, running on a single node
  • A database that Confluence reads and writes to

See Getting started as a Confluence administrator to learn more about single server Confluence installations. 


Non-clustered Confluence Data Center installations have the same minimum requirements as a Confluence Server installation. Check our Confluence System Requirements guide for a full overview of the supported platforms and hardware you’ll need.

Benefits of running a non-clustered Data Center deployment

There are a range of reasons you may choose a single node Data Center. Some of the benefits include:

  • Keeping your existing infrastructure
    Running on a single node means that you can upgrade from Server to Data Center without adding to your infrastructure. In most cases, moving to Data Center will be as simple as updating your license.

  • Accessing Data Center-only features
    Your Data Center license unlocks a suite of additional security, compliance, and administration features to help you easily manage enterprise-grade Confluence site – like SAML single sign-on, advanced permission management, rate limiting, and more. See the complete list.

As non-clustered Confluence Data Center installations are cluster-compatible, you can still enable and configure clustering whenever you’re ready to scale. Learn more about setting up a cluster.


Non-clustered Data Center is the simplest setup, but it has some limitations. You’ll still have the application server as a single point of failure, so it can’t support high availability or disaster recovery strategies.

Some deployments start to experience performance or stability issues once their size profile hits Large or XLarge. Most clustered deployments provide you the flexibility to scale up your infrastructure to address heavy loads (or even scale down to save costs during light loads). On AWS or Azure, you can also quickly address most stability issues by replacing misbehaving nodes with fresh ones.
