Power BI: What's the difference between "My Workspace" and the other "Workspace"?
Updated: Jun 16, 2020
What is it: This is a personal workspace for you. No one can access it unless you share it.
Use Case: Good for personal projects or just testing purposes. Can also be shared with other users (if you and they have a Pro license).
Do not use if: If you are developing a dashboard with a team, you should use a company workspace.
Why?: The issue comes when publishing. If you publish a dashboard to your own "My Workspace", other developers cannot publish to the same (your) "My Workspace". See below for my personal experience with this.
What is it: These are company wide workspaces just like "My Workspace". Can be shared but everyone still needs a Pro license.
Use Case: Should be used for publishing a dashboard where multiple users are accessing it.
Do not use if: There may be cases where your dashboard exposes sensitive data which should only be seen by management. Because it's on a shared workspace, anyone can access it (unless you design the workspace for specific people which can be found hiding under the Advanced section).
Bonus: Can create dataflows with these workspaces. Dataflows cannot be created with your personal workspace.
My Personal Experience.
There once was a time where I developed a dashboard for my client and published it to "My Workspace". This dashboard was shared with multiple groups in the company, had RLS, the whole shebang.
This was okay for the time being because I was the only one managing it. However, the I eventually needed to pass this dashboard to another developer. Because it was published to My Workspace, they needed to recreate all of the shared connections on their end. If I had used a company workspace, the transition would have been much smoother.
