Jira Data Center ?

[Absa Thiam]

Hello,
Please help me to see more clearly

I started to use Jira Server not long ago now I want to migrate to Jira Data Center but I don't know which deployment to use Cluster? or not Cluster?
Because I don't really understand the term Cluster

To specify that in my company we have 11 users and we all use only one application of Jira and it is the Cloud

I would like you to help me choose a deployment mode

Thanks in advance

Make sure you don't have the jira-users group in the permission scheme. By default, JIRA puts the group many, if not all, permissions. Some versions of JIRA have a different name, but it is the group all users are put so they can logon to the application.

Hi Marcin

You can create a new project role called "read only" for example

In the permissions scheme used by your project grant the "browse projects" permissions to this role. That should be the only one a read-only user needs

Then in your project add the members to the the new read only role. And make sure that those users are not in one of the other project roles
