Leveraging the power of the cloud is essential to success in today’s digital age, especially as organizations increasingly move their applications to the cloud to drive growth. As per a report, global spending on public cloud services is projected to increase to 304 billion USD in 2021 as compared to 257 billion USD by 2020. By the year 2024, more than 45% of IT spending will go from traditional solutions to the cloud.

What is Cloud Migration?

Cloud migration has many misconceptions but it is not only just about the movement of the cloud; it is a repetitive optimization process to reduce costs and reach the full potential of the cloud. It affects all aspects of the organization, including people, processes, and technology. However, with flexible consumption and pricing models, the cloud can support high scalability, performance, flexibility, telecommuting, and cost-effectiveness.

The path to the cloud is different for each organization because there is no single migration plan. Each IT asset transferred is unique in terms of cost, performance, and complexity. Therefore, not all components can be moved to the cloud by a single common method. The preparation of a transition action plan answers the questions of what, how, and in what order to move these components. This is where cloud migration strategies come into play.

The 6 R’s of Cloud Migration

1. Replatforming

This “lifting, pinching, and moving” strategy is a modified version of relocation. Replatform allows you to make some configuration changes to your applications to better suit your cloud environment without changing their underlying architecture. Developers typically use this approach to make applications interact with the database so that they can run on managed platforms such as Google CloudSQL or Amazon RDS. 

2. Repurchase

It is sometimes referred to as “throw and buy” because it refers to a decision to switch to another product. This may mean terminating existing licenses and relocating services to new platforms or services. Often, this may not be a custom application, but it may be one that does not have modern application code or a situation where the code cannot be transported from one provider to another. 

3. Rehosting

This strategy, commonly known as lifting and switching, is a widely chosen strategy due to its relatively low migration effort. The virtual machine and the built-in application are simply copied to the cloud service provider. The most important advantage of this strategy is the speed of migration, as there is no need for architectural redesign. In addition, migration can often be done automatically using various lifting and moving or so-called workload mobility tools.

4. Retain

You may want to keep part of your IT portfolio because some applications that you are not ready to migrate are more convenient to keep on-site, or you need to do so to ensure compliance. In this use case, it may make sense to maintain aspects of your IT services in the current environment and implement a hybrid or part migration strategy. 

5. Retire

The retirement strategy means that the application will be explicitly terminated. This is reasonable if the business opportunities offered by this application are no longer needed or are offered in excess. We often see this in cases where organizations have recently gone through mergers and acquisitions. You should consider the cloud transformation project as a welcome way to screen your application portfolio and reduce obsolete applications on the go.

6. Refactor

This is basically a rebuild. This is usually due to a strong desire to improve the service or application. This may be due to difficulties in improving the current environment or the need to improve the immediate availability and reliability of the application in the event of expected traffic and operational outbreak.

Conclusion

The 6 R’s of cloud migration is extremely important for businesses and bringing structure to your decision process. Hence, it is mandatory to put extra effort into researching and making the right decisions.
