Cloud-based business resilience—a welcome, new approach
Cloud computing offers an attractive alternative to traditional disaster recovery. "The Cloud" is inherently a shared infrastruc ture: a pooled set of resources with the infrastructure cost dis-tributed across everyone who contracts for the cloud service. This shared nature makes cloud an ideal model for disaster recovery. Even when we broaden the definition of disaster recovery to include more mundane service interruptions, the need for disaster recovery resources is sporadic. Since all of the organizations relying on the cloud for backup and recovery are very unlikely to need the infrastructure at the same time, costs can be reduced and the cloud can speed recovery time.
Cloud-based business resilience managed services like IBM SmartCloud™ Virtualized Server Recovery are designed to provide a balance of economical shared physical recovery with the speed of dedicated infrastructure. Because the server images and data are continuously replicated, recovery time can be reduced dramatically to less than an hour, and, in many cases, to minutes—or even seconds. However, the costs are more consistent with shared recovery.
