In case you already have created Environment Groups, you can set some rules to divert how environments are created to Environment Groups.

If not, you might want to first take a look at a post on Environment Groups in Power Platform Admin Center!

Environment Routing is feature to redirect existing/new Makers to their own Developer environment when logging into the Maker Portal (https://make.powerapps.com/)

Routing in Environment Groups

Here’s how you can set Routing rules in Environment Groups in Power Platform Admin Center –

1. Given that you have the correct Dynamics 365 Administrator privileges, you should be able to see the Environment Groups section and also see button to set the Environment Routing.
   
   
2. In Environment Routing, you can choose to enable to Create personal developer environments for makers option.
   
   
3. When you turn it on, you can choose to enable it either for All makers or for new makers only. I’ll enable it for All makers for this example.
   
   
   
4. Now, I’ll select the Environment Group where the routing should happen to – for this, I’ve created a CFT Developers Environment Group.
   
   
   And Save.
   

Routing to Developer Environments

Let’s consider this example to demonstrate how Routing will work –

1. When a developer logs into the Maker Portal (https://make.powerapps.com/), a setup will load for a few moments the user, let’s say, Amit Prajapati in this example, will be redirected to his own Portal –
   
   
2. And if you look at the list of the Environments in the Group you selected for Routing, you’ll see that Amit’s Environment is now created.
   
   
3. Now, another User Ethan Rebello also logs into the Maker Portal. He too will be redirected to his own environment.
   And the same will be added to the Group as well.
   
   
   Every developer will have access to only their own Developer environments and other’s won’t be able to access them.

Hope this was useful!

Thank you!
