For those that use Veeam VCC there was an online reference by Luca Dell’Oca which was a reference architecture and best practice on setting up VCC. He has now updated the online resource to v11 so you can check it out here - Veeam Cloud Connect 11 Reference Architecture - Veeam Cloud Connect 11 Reference Architecture (vccbook.io)
Very great reference for those in the Service Provider realm.
