Abstract: In an example, a computer implemented method may include assigning credits and a credit limit to a user account. The credit limit may indicate maximum credits that can be used to perform each operation in a data center. Further, the method may include receiving a request to perform an operation on a data center resource from a user associated with the user account. Upon receiving the request, a value corresponding to the requested operation may be retrieved from an attribute associated with the data center resource. Furthermore, the method may include determining whether the user is permitted to perform the requested operation on the data center resource based on available credits of the assigned credits, the credit limit, and the retrieved value. Further, the method may include controlling an access to perform the requested operation based on the determination.
