VMware Cloud on AWS accounts are based on an Organization, which corresponds to a group or line of business subscribed to VMware Cloud on AWS services.
Each Organization has one or more Organization Owners, who have access to all the resources and services of the Organization and can invite additional users to the account. By default, these additional users are Organization Users, who can create, manage, and access SDDCs belonging to the Organization, but cannot invite new users.
The VMware Cloud on AWS Organizations that you create or are a member of have no relationship to AWS Organizations.
Both types of accounts are linked to a My VMware account.
