Cloud accounts are the configured permissions that vRealize Automation Cloud Assembly uses to collect data from the regions or data centers, and to deploy blueprints to those regions.
The collected data includes the regions that you later associate with cloud zones.
When you later configure cloud zones, mappings, and profiles, you select the cloud account to which they are associated.
As a cloud administrator, you create cloud accounts for the projects in which team members work. Resource information such as network and security, compute, storage, and tags content is data-collected from your cloud accounts.
If you remove a cloud account that is used in a deployment, resources that are part of that deployment become unmanaged.
