Create a Configuration Management Roadmap
Without a configuration management database (CMDB) or formal configuration management, there is no way to obtain information about the assets that support IT services or the relationships between them.
This makes it difficult for IT departments to successfully execute more client-facing service management activities, particularly incident and change management.
Most organizations recognize the value of investing in a CMDB, but are wary of the cost involved and assume that the CMDB must contain information about every IT asset.
Clients who do decide to invest in a CMDB often jump straight to solution selection and design, without ever considering the business case for building or purchasing a CMDB.
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.
