Can CGS Be Shared by Multiple Accounts?

No. For example, if you have two accounts (domain1 and domain2) in a region, and purchase CGS under the domain1 account, you cannot use the service under domain2.

In the same region, all the IAM users of an account can use CGS purchased under the account. Assume you have created a Huawei Cloud account (domain1) in a region, and created two IAM users (sub-user01 and sub-user02) under domain1. If you have granted the CGS permission policy to sub-user01 and sub-user02, both of them can use CGS purchased by domain1.
