Abstract: A system that leverages the Operational Support System(s) (OSS) and Business Support system(s) (BSS) of a (e.g., public) computing Cloud with a service to automate virtual instance restarts. A failed virtual instance is detected within the Cloud computing environment, and a request for a new virtual instance is received in response thereto. Upon receiving the request, an entitlement of a user associated with the failed virtual instance is tested. A set of authentication calls and checks are deployed to ensure the integrity of the requests, as well as the authorization of the requester for the resource use. Assuming testing is passed, a countdown timer associated with the failed virtual instance will be decreased. When the countdown timer reaches a predetermined threshold (e.g., zero), the new virtual instance will be started, the failed virtual instance will be terminated, and the countdown timer will be reset/restarted by instance.
