Is it better to have JIRA and mysql on the same server, or to have the database on a separate server?

Depends on your needs.  Using the same box reduces network traffic and dependencies and keeps things very simple - "that box runs all of Jira".  But a separate server means you know that the database server processes won't consume resources that JIRA could be using and vice-versa.  So there's no simple answer to this one really!

As Nic said, it depends. We have jira with 2000+ user and we have both database, jira and confluence on same server.

That also raises the question: What amount of resources does the database consume?

Not a lot, unless you start trying to do "clever" things like ignore the API and talk directly to it, or run reports of it etc. Jira databases tend to be small - most users will find the database chews up a few Gb at most. On a well-tuned/monitored Jira, you'll mostly find the CPU ticks over at a couple of % usage most of the time. However, that said, it's really not easy to just say "well you can just use a small weak machine". It depends on your usage. Whatever you do, monitor the database service.

rule of thumb its to always have them separate but, they are small environments were they keep it together. I have a small environment with 20 users and i keep both of them together because i dont want to manage another server.

what is a threshold for switching to multiple servers? 200 users? 500? with proper backups having a simpler setup and reduced chance of a network botlleneck outweighs a generic rule of thumb for me

Hi Rich, if your enviroment is big enough I would recommend you to have in different servers. Plus, if your JIRA server goes down you can have a second enviroment and point it to the database. Remember is not recommended to have two working enviroments pointing to the same database.

Different server for good performance is suggested.
