Hi,
Configuration Manager's Azure service for Cloud management supports multiple tenants. Multiple Configuration Manager sites can connect to the same tenant. A single site can deploy multiple CMG services into different subscriptions. Multiple sites can deploy CMG services into the same subscription. Configuration Manager provides flexibility depending upon your environment and business requirements.
Create the CMG at the top-tier site of your hierarchy. If that's a CAS, then create CMG connection points at child primary sites. The cloud service manager component is on the service connection point, which is also on the CAS. This design can share the service across different primary sites if needed.
For more information, please refer to the official article: CMG hierarchy design
Hope it helps. Thanks for your time.
Best regards,
Simon
