Implement a Shared Services Model
Implementing a shared services model is a difficult process to undertake, and is comprised of many different components. Becoming a shared services provider is comparable to becoming a vendor and most IT groups don’t have the capabilities to easily make the transition.
Most companies look to achieve cost reductions through offering a shared services model. Adopting a shared services model doesn’t always result in these intended cost reductions. Simply combining the operations of two IT organizations doesn’t necessarily result in economies of scale and cost efficiencies. Before leaping forward with your shared services implementation, determine if the project will deliver value to your organization.
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.
