Does JIRA support clustering for scaling?
Not at this time.
However we do understand that customers are interested in how JIRA can scale. To address this we have written a document that explains how JIRA performs in different configurations and it also provides a guide of how to scale JIRA in a large enterprise. So whether you are a new JIRA evaluator that wants to understand how JIRA can scale to your needs, or you're a long time existing JIRA administrator that is interested taking JIRA to the next level we have a document that will point you in the right direction.
To scale JIRA in your organization, there are two key approaches, which can be used in combination to scale JIRA across your entire organization:
- Scaling a single JIRA instance.
- Federation: Using multiple, connected JIRA instances
We detail both techniques to get the most out of JIRA for your organization at our Scaling JIRA guide.
What if I really want JIRA clustering?
Although not supported if this is something you must have then in your environment you may wish to work with one of our Atlassian Experts to come up with a tailor made solution. Please remember that this will not be supported by Atlassian. This means that if you experience a problem that can not be replicated in a non-clustered environment then that is where our support will most likely stop.
Note: If you wish to run JIRA in a clustered environment you will need a license for each node. You can place your order from our secure online order form.
Does JIRA support high-availability?
While not natively supported it is possible to build an environment with a JIRA failover strategy. This best practices guide: Failover for JIRA, assembles some of the best advice from our customers, our partners, and internal staff on setting up a failover solution for JIRA.
