ADAM (Advanced Database & Application Migration) supports two account types for logon: an Alibaba Cloud account and a RAM user. Choose the account type that matches your access needs.
Alibaba Cloud account
An Alibaba Cloud account can be used to log on to ADAM.
RAM user
A RAM user must have one of the following policies attached before logging on to ADAM:
| Policy | Access level |
|---|---|
AliyunADAMFullAccess | Full access to ADAM |
AliyunADAMReadOnlyAccess | Read-only access to ADAM |
To attach a policy to a RAM user, see Grant permissions to RAM users.
Data visibility
A RAM user inherits all data of the Alibaba Cloud account it belongs to. Data generated by one RAM user is visible to all other RAM users under the same Alibaba Cloud account.
