Can CBH Manage Resources Under Multiple Subnets?

Yes.

If your CBH instance and the resources you want to manage with CBH are in the same VPC, the CBH system can directly manage resources in multiple subnets in the VPC as subnets in the same VPC can communicate with each other.

The CBH instance and the resources you want to manage must be in the same region and VPC. For details, see Network Access Restrictions. If your CBH instance and the resources you want to manage with CBH are in two subnets in different VPCs, a cross-VPC connection must be established to enable communications between the two subnets as subnets in different VPCs cannot directly communicate with each other. You can create a VPC peering connection to enable communications between them. While this method is not recommended as cross-VPC connections are not stable enough.
