A method for dynamically updating a service level agreement, performed by a cloud computing server, includes storing a preference for service selection, acquiring an actual usage level of a first service provided to a user during a predetermined time period in accordance with a first service level agreement, determining a second service level agreement different from the first service level agreement based on the actual usage level acquired during the predetermined time period, and selecting a second service that satisfies the second service level agreement.
