Any good disaster recovery (DR) plan mitigates against a variety of different scenarios that might bring a service down or otherwise cause an incident.

Good DR plans also connect those scenarios to goals such as high availability (HA), plus metrics for measuring performance against those goals. Common examples include data recovered—how much was lost?—and time to recovery—how fast was the service restored?

These principles have long been in place and remain largely true today. But much of the thinking about DR remains ingrained in on-premises infrastructure, which unnecessarily limits companies from bolstering their DR strategy and response to today’s incidents with new ways of doing things in the cloud.
