Bridge the Gap between Service Management Disaster Recovery StoryBoard
If a tornado destroys your data center, that’s an obvious DR scenario. However, the vast majority of extended service interruptions are caused by relatively minor events, such as hardware issues, isolated power or network outages, etc., that typically fall initially under service management procedures.
IT leaders can fall victim to the “IT hero” and the familiar refrain of “I just need five more minutes,” or maintenance crews promising that it should only take a couple hours to restore power or network connectivity, and wait too long to initiate DR procedures.
On the other hand, declaring a disaster is rarely a no-cost scenario, and should not be done lightly. For example, vendors often apply a surcharge to activate a hot site. At the very least, it’s a disruption to previously scheduled work as both IT and business leaders convene to manage the DR. IT leaders need guidance on when to escalate to DR procedures.
Keep your systems dormant until disaster strikes. Prepare as much of your environment as possible without tapping into compute resources. Enjoy the low at-rest costs, and leverage the reliability of the cloud in your failover.
Avoid failure on the failback! Bringing up your systems in the cloud is a great temporary solution, but an expensive long-term strategy. Make sure you have a plan to get back on premises.
Leverage cloud DR as a start for cloud migration. Cloud DR provides a gateway for broader infrastructure lift and shift to cloud IaaS, but this should only be the first phase of a longer-term roadmap that ends in multi-service hybrid cloud.
Impact and Result
Calculate the cost of your DR solution with a cloud vendor. Test your systems often to build out more accurate budgets and to define failover and failback action plans to increase confidence in your capabilities.
Define “good enough” performance by consulting with the business and setting correct expectations for the recovery state.
Dig deeper into the various flavors of cloud-based DR beyond backup and restore, including pilot light, warm standby, and multi-site recovery. Each of these has unique benefits and challenges when done in the cloud.
