Use of cloud for DR solutions is becoming more common, even the organizations which are not using cloud for mission critical production applications are moving towards using cloud for application DR.
Faster Recovery Time Objective (RTO): Typically DR requires lengthy manual processes to fully restore the business applications at the DR site. Having backup data and servers at the DR site is easy, however, restoring the entire application or service takes time. E.g. full application restoration requires starting services in specified order, performing dns and other configuration updates etc. In Cloud, the IaaS APIs provide ability to use automation solutions like Kaavo IMOD to fully restore the business applications automatically without manual intervention. As a result organizations get predictable recovery and reduced RTO. Automating the service or application recovery can reduce RTO to minutes from hours or days.
