DRaaS is the future of disaster recovery, but leveraging cloud backup may be an expensive way to implement it. Cloud replication, because it is operating on the working set, keeps cloud storage costs contained. The cloud replication software also enables organizations with an IT ready secondary site to leverage that site and create their own DRaaS. In either case, the organization is in control of when and how recovery happens. DRaaS built on replication also enables organizations to use the replication software to enable other cloud initiatives like bursting and test/dev. In this article Storage Switzerland explores the various methods to go about creating and implementing a DRaaS solution.
