The 5 R's of Cloud Migration

A successful cloud migration comes with an enormous list of benefits. Amongst the top benefits are that it optimises businesses to scale, it’s cost-effective, and heightens the overall performance.

Cloud services are the crux of seamless business support and accessibility, two indispensable drivers of sustainable growth and development. Thus, it makes sense why businesses and organisations are turning (in such large quantities) to cloud based storage platforms.

A carefully-constructed migration strategy, that successfully delivers powerful cloud solutions, can make a massive difference when it comes to a smooth transition to the cloud. Information technology research company Gartner, has previously outlined what has now been coined as the ‘5 R’s’ of cloud migration strategies.

The 5 R’s include:



Rehosting refers to the reformation of an application to a different hardware environment. It changes the infrastructural composition of an application. If your application is already on the cloud then rehosting becomes a significantly simpler task.



The cloud gives businesses the adequate infrastructure to run the application. It combines awareness and speciality. By deploying PaaS it suggests that developers are able to reuse containers, languages and frameworks which have already seen investment.



This phase involves two steps. The first step is altering existing code. Once the code has been modified in such a way that it supports the needs for legacy modernisation. Following this, the next goal is to rehost or refactor the options to mobilise to the cloud.



This stage is all about rebuilding. So far, we have discarded the initial applications’ code, re-architected the application and now we are setting off to rebuild the solution of PaaS. By doing this, we are guaranteeing the loss of the cognition of the existing codes and frameworks.



At this point, we begin to replace the use of commercial software and discard the pre-existing application.
