Is Enhance installed on a dedicated server?

I’ve looked all i can but haven’t found clarity for this..

Is Enhance installed on a dedicated server once and manages your web servers from there?

Or does it get installed on all individual servers with the websites?

Thanks

Enhance First gets installed on a fresh empty ubuntu VPS or dedicated server to setup the main controller and interface.
For each extra Virtual machine or Dedicated server you add, you install the Enhance using the install URL generated by the controller. This 'registers' the new server to the controller.
Within the controller, you can assign roles such as 'Web Server' onto servers you've added so you can add websites.
All interactions regardless of what server they are on are done through the main controller. The individual servers do not have web-interfaces like cPanel, Directadmin and most other panels.
Nothing gets installed in the individual websites, the entire structure is already created and you just then upload or migrate your website in
