Having multiple instances of Atlassian

[Talha Farooq]

We are planning to have 3 separate instances having standard licensing subscription of Atlassian within our organisation. 

Is it possible to have same domain for each instance? For example, our domain is @email.com, can this be implemented across multiple instances? 

In case they all have their own domains, for example, @email1.com, @email2.com and @email3.com.

Is it possible to configure SSO while all instances have their own domains.

Hi @Talha Farooq , No that would not be possible. There needs to be a 1:1 relationship between Atlassian instance and domain. Might I inquire as to why you need three instances instead of one? Please note @email1, @email2, @email3 represent separate domains.

Hi @Jack Brickey what is not possible? Just a use case I have in my mind. In case we go with three instances, we will have 3 separate domains? Can I then claim these domains from one of the instances and implement SSO?

@Jack Brickey ,

Isn't Atlassian Access available for a specific organisation which can then hold multiple instances?

True a instance has it's own domain ( abc.atlassian.net, def.atlassian.net, ... ) but is it not so that the IdP used with Atlassian Access can be used for all instances under the same organisation?

[Jack Brickey]

@Dirk Ronsmans , Yes that is my understanding though I have not used Access myself. @Talha Farooq , something to consider and investigate.

Yes, that's correct.  Adaptavist uses Okta + Access for all of our Cloud Atlassian sites (and we've got a lot - we spin them up for dev/test, but also for handling projects with clients)
