My operations team has recently moved from redmine to JIRA/Confluence/Stash for project tracking. In redmine, we had one project for each of the 150+ services that we provide. This allowed us to easily browse the history of a particular service, bundle documentation along with the service, etc. I initially migrated our projects straight across to JIRA, and do like some things about having a separate project per service, but limits the value of some of JIRA's features, such as reporting and use of GreenHopper, both of which seem geared more towards single projects. With 100+ projects for a single team, I'm wondering if this is really the best way to do this.
How are others using JIRA for ops teams? Are there other ways that I should be thinking about project taxonomy?
