We are currently running Jira, Confluence and Jira Servicemanagement all on the same server. We are aware of the changes that have been made regarding Jira Data Center and are planning our migration in the near future. Will everything still run on the same server or can the applications like JSM be broken out to run on their own server?
Jira Software and Jira Service Managements are "Applications" that run on the "Jira Platform". The Jira Platform is Jira Core as far as we users are concerned.
If you were to split your JSM and Software off on to another server each, you'd end up with one server running Jira Core, a second with Jira Core + JSM and a third with Jira Core + Software.
The three systems would not share data directly, it would make people working on one of the three harder to collaborate with than keeping it all in one place.
Confluence is a separate service in its own right. If you're concerned that your servers are not powerful enough to run Jira and Confluence, then by all means move one of them on to another server, Jira and Confluence are two independent systems. But there's no gain to be had by breaking up your Jira.
I have not mentioned data-centre yet - that's because it's pretty much irrelevant to this subject. You could be running Jira on a single server, or on several DC nodes, it doesn't make any difference to whether you choose to split up your systems or not.
Thanks for your reply..
Yes, we currently are running JIra Core, Jira Software and JIra Service Management on the same server. We are planning to migrate to Jira Data Centre within the next year or so and were curious about the requirements and whether one monolithic server is also required or if multiple servers can be used.
You can do everything on one server (obviously, for DC, a single server means a single node in a cluster, so you wouldn't be getting any of the benefits of load balancing or resilience), or yes, you could split things out onto different ones.
The default position most people take is
But that's not a requirement at all, you can do it any way you want as long as you give each service enough resources to work.
