Develop an Availability and Capacity Management Plan

Your Challenge

It is crucial for capacity managers to provide capacity in advance of need to maximize availability.
In an effort to ensure maximum uptime, organizations are overprovisioning (an average of 59% for compute, and 48% for storage). With budget pressure mounting (especially on the capital side), the cost of this approach can’t be ignored.
Half of organizations have experienced capacity-related downtime, and almost 60% wait more than three months for additional capacity.

Our advice

Critical Insight

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.
