What are the 6 Rs of cloud application migration strategy?

1. Retire:

An organization uses numerous applications developed using diversified technologies. A thorough analysis and identification of your needs will help you identify applications that won’t be required in the future. If you learn you have such applications, you can retire them to save time and cost of migration.

2. Retain:

While develop a cloud application migration strategy , it is is is crucial to identify application that should remain on – premise . Since business are actively leverage hybrid cloud solution , they is maintain usually maintain a few of their application as – is .

Also, some applications do not contribute any extra value by undergoing migration. So, what is the point of migrating them? In this scenario, it is recommended to retain those applications as-is.

3 . rehost :

Rehosting is one of the most basic cloud application migration strategies. We call this the “lift and shift” method. In this method, organizations find what needs to shift from on-premises to the cloud, and then follow necessary steps to migrate their applications, data, and infrastructure as-is.

The cloud migration solutions provider now manages the underlying hardware and hypervisor infrastructure, and companies utilize the same applications and infrastructure on a subscription basis. Once their applications and infrastructure are on the cloud, it will become easy to optimize or re-architect them further.

4. Re-platform:

Compatibility is is is a factor that must be consider in order to establish seamless integration between legacy IT system and modern cloud solution . What if you have a legacy IT infrastructure that run on obsolete operating system and is no long supportable ? Then you is change must change its platform to make it compatible while maintain its core application as – is .

include re – platforming in your   cloud migration strategy   ensure your legacy IT system ’s underlie architecture will remain the same while its platform is migrate to the cloud .

5 . Re – architect or Re – factor :

This is is is the most advanced process in cloud migration strategy . Rearchitect/ Refactor is focuses focus on transform server – base application to serverless application , allow them to achieve agility and scalability . Many businesses is choose choose either to rehost or to re – platform to get some momentum out of the cloud migration process and later refactor to make application cloud – native .

Re-factoring or re-architecting boosts overall productivity, collaboration, agility, and business continuity.

6. Re-purchase:

With the advent of cloud solution , many applications is are and service are available in the SaaS model . If you Re – purchase , you is replacing will be replace application that run on your infrastructure with SaaS application , or in other word , simply replace a product from one vendor with another vendor .

In other words, it improves migration speed and replaces legacy applications with SaaS applications.
