Understanding the difference between Confluence Server & Data Center

There are two products that allow you to run Confluence in your own environment: Confluence Server and Confluence Data Center. If you're already familiar with Confluence, you may already be using Confluence Server.

We want all teams to get the most out of Confluence, so the core features are available for everyone on Confluence Server and Confluence Data Center.

Some features are available specifically for customers with a Data Center license. These may be specific to the needs of larger enterprises, or may provide additional infrastructure or administrative options to help you strike a balance between growth and control of your Confluence instance. These features include:

You can now access Data Center features on your current infrastructure by simply applying a Data Center license. Or, if your organization needs the benefits of a clustered architecture, you can set up clusters before migrating to Data Center.

* For a full feature comparison between Server and Data Center, see our documentation site.

If you choose to run Confluence Data Center in a cluster, each cluster includes:

  • Multiple server nodes for Confluence
  • Multiple server nodes to run Synchrony, the engine that powers collaborative editing
  • A shared file system

Getting started

Whether you're upgrading from Confluence Server or spinning up a new instance of Confluence Data Center, setting up a new install of Confluence is no easy task. As an administrator, you'll need to set aside time to understand the requirements, make a plan of attack, and execute on it. You might also encounter roadblocks, such as bureaucratic or budgetary constraints within your organization.

We're confident that the benefits of upgrading to Confluence Data Center—including high availability, read-only mode, advanced permissions management, infrastructure choice and scalability—will make this investment of time and effort worth it for you, your team and your organization's users.

In the next section, you'll find helpful tips and links to technical documentation you'll need to be successful.

Performance recommendations and requirements

You can run the Confluence Data Center application on a single server, just like a Server installation. This allows you to take advantage of Data Center-only features without adding to your infrastructure.

Or, you can run Confluence Data Center in a cluster with multiple application nodes, and a load balancer to direct traffic. If you don't already have a load balancer, shared file system, and supported database, it's time to make the necessary procurement requests. You can find a full list of system requirements on our documentation site.

Regardless of how you deploy, there may be hardware investments required. Once you check these requirements, you'll also need to tune Confluence for improved performance and ensure you and your team have the right skills and tools to investigate your instance's performance.

On-premise vs. infrastructure as a service

One of the benefits of Atlassian's Data Center products is infra- structure choice. You can deploy on-premise or with infrastructure as a service (IaaS) vendors like AWS and Azure to best suit your company's existing investments. In fact, more and more customers are choosing to deploy Atlassian tools using IaaS providers: 62% of Atlassian’s self-managed customers are choosing to deploy their applications on a virtual architecture.

Consider which option is better for your organization, and read more about your Atlassian products and IaaS on our blog.

Review your disaster recovery strategy

Partial or complete system outage? Avoid chaos and keep business running smoothly with a disaster recovery strategy. With disaster recovery for Atlassian's Data Center products, you can configure index replication, attachment updates, and database synchronization to comply with your DR plan's specific requirements.

No two disaster recovery plans are exactly alike. Learn how to use Confluence Data Center to implement and manage a disaster recovery strategy for Confluence in our documentation.
