Problem
What is a "space"?
Solution
A space is a logical collection of "resources" like a "folder". You may group resources because of charging restrictions or specific projects. You may create as many spaces as you like.
Why you would organize resources into a single space:
Same application or project.
Same data risk level (med, high, HIPAA, etc).
Same billing, COA.
Instances have all port access to other instances in same space.
