We are a few company's which are at the moment uses different licenses and different Versions of Jira, Confluence and Service DESK. We have all the Server license.
Now with the change of Atlassian's license model, we think about a data center.
The problem is, that do not know if we could use it at the same time but use different instances for each company.
We are not allowed that all of that company's uses the same instance and are only separated with the roles and rights of the system.
So is it possible to use the data center solution, but setup different intances of it to completely separate the company's? But we do not want to buy different licenses for each company (that's too much money). All the company's are not more than 500 users.
We are also not able to change to the cloud, because of german data privacy laws.
