METHOD AND APPARATUS FOR RAPID DISASTER RECOVERY PREPARATION IN A CLOUD NETWORK

摘要

Various embodiments provide a method and apparatus of providing a rapid disaster recovery preparation in cloud networks that proactively detects disaster events and rapidly allocates cloud resources. Rapid disaster recovery preparation may shorten the recovery time objective (RTO) by proactively growing capacity on the recovery application(s) / resource(s) before the surge of recovery traffic hits the recovery application(s) / resource(s). Furthermore, rapid disaster recovery preparation may shorten RTO by growing capacity more rapidly than during "normal operation" where the capacity is increased by modest growth after the load has exceeded a utilization threshold for a period of time.
