In most circumstances, cloud repatriation—or a cloud exodus, as it is frequently called—is probably not the best option. Yet occasionally, it really is the proper thing to do.
Although the shift to cloud computing is still expanding steadily, there are occasions when an organisation chooses to leave the cloud or bring some workloads back on-site. Although it’s not common, a cloud exit is a means for companies to take back control of their spending and manage workloads that they think aren’t performing well in a public cloud environment.
According to Hyoun Park, CEO and lead analyst at Amalgam Insights, “Workloads expand in volume and complexity [in the cloud] and demand additional services to support.” Even with generally regular workloads, this can cause an organization’s costs to treble or triple quickly. The fact that Amazon generates operating income over $2 billion per quarter is not by chance, according to Park.
Managing a cloud departure
According to Medford, a cloud departure is merely a reverse of the initial cloud migration. Sadly, putting a cloud exit strategy into action isn’t always simple. According to him, repatriation is always handled on a case-by-case basis and there is no magic formula.
Yet, switching to an on-premises environment when an application is created, at least in part, to operate in the cloud entails abandoning all of that work and returning to the original architecture and design, according to Medford.
Sokolov sees five main aspects that should be considered in each cloud exit strategy, despite the fact that each reversal is distinct and necessitates specific methods.
- 1.Make a careful plan: “The process of returning to an on-premises system takes time. You must thus create a thorough, step-by-step plan and prepare for a number of problems “explained Sokolov.
- 2.Plan your deployment:Â To ensure that your application deploys quickly and reliably, automate deployment and run a thorough test.
- 3.Consistently transfer data: Every move entails that data will occasionally reside both locally and in the cloud. You must ensure that your app can address these delays because they frequently result from situations like these, according to Sokolov.
- 4.Be in command: Prepare to handle all tasks that formerly fell under the purview of a cloud provider, such as infrastructure and security
- 5.Support it:Â “You need to have a backup strategy that can shield your company from such insignificant but fatal mishaps as a power outage.” According to Sokolov, a hybrid computing model may be useful.
