Thousands of Atlassian customers run more than one JIRA instance in their organization. This is one of the reasons why in the JIRA State of the Union 2012, Federation was mentioned as a key part of the JIRA product strategy!
In line with that announcement, we have released the Federating JIRA Enterprise Guide to centralize best practices in administering, managing and running JIRA federations.
Do you run multiple JIRAs in your organization?
Which reasons to federate were most relevant to you?
How do you connect them? Application links? Any custom interfaces you developed?
Looking forward to comments, shared best practices and also questions!
