Aliases are optional identifiers of a customer master key (CMK) and must be unique for the same user in a region. An alias can be bound to only one CMK in a region, but a CMK can have multiple aliases.
An alias must exist based on the CMK. Features:
Multiple aliases can be bound to a CMK, and deleting an alias will not delete its associated CMK.
The alias cannot be modified. You can create a new alias for the CMK and delete the original alias to modify the CMK.
You can call the UpdateAlias API to change the CMK bound by the alias without affecting the CMK.
You cannot delete and add aliases for the default CMK.
