What are the 5 R’s of application modernization?

Rehost 

Rehosting is the most common strategy in application modernization.

It is often referred to as the "lift and shift" approach. This means that you do not make major changes to the app architecture. Instead, you migrate the application and the underlying infrastructure to the cloud.

Rehosting is best when your priority is to free up the datacenter space. Plus, rehosting enables you to leverage the benefits of advanced and modern technologies like the cloud. 

Refactor

Application modernization services will help you refactor your legacy applications. It simply means to make structural changes or modifications to the application’s code while preserving its core functionality. 

This is possible by adopting modern architectural patterns like microservices, containers and serverless computing. This gives businesses the flexibility, scope to scale and agility they need for growth in the present and future.

Revise

Revise application modernization strategy means modifying the application's codebase. This is done to enhance the app's performance, user experience and functionality.

Revising process includes rewriting algorithms, amending modules and improving the interface. 

You should go for this approach when your legacy applications require rearchitecting to take full advantage of the cloud. There are applications which are not well designed or built. You cannot simply migrate them to the cloud. Therefore, you will first have to modify its core architecture to make it ready for the cloud.

Rebuild

Rebuilding refers to the complete recreation of applications using contemporary development frameworks, tools, and methods. This approach opens doors to eradicate technical debts, boost performance, and integrate fresh functionalities. 

Yet, it demands meticulous planning, weighing aspects such as project scale, resource distribution, and seamless data transfer. 

Comprehensive documentation and cohesive teamwork among development units, supported by application modernization services, stand as crucial pillars for a seamless reconstruction journey.

Replace

Replace application modernization strategy is completely replacing your legacy application with new or customized solutions. 

This is suitable when the existing applications are entirely obsolete. Plus, it no longer meets business goals or requirements. 

Further, the replacement approach is best when getting new solutions is more cost-effective and relevant than rebuilding or rearchitecting the application.

Throughout the replacement phase, organizations ought to perform a comprehensive assessment of the available choices, taking into account elements such as compatibility, scalability, vendor support, and the seamless transfer of data.

Which application modernization approach is best?

As you can see there are different strategies for unique requirements and business goals. 

So, it won't be right to think that one strategy will fit all your applications. Every application has its own functionality and requires a unique approach to align with the changing market dynamics and business objectives.

With a meticulous examination of their applications' strengths, weaknesses, and needs, you can select the most fitting strategy and unlock the advantages of modern technologies. 

Whether it's transitioning to the cloud, embracing microservices, or completely rethinking applications, the 5 R's empower businesses to convert their legacy systems into resilient, scalable, and future-proof solutions.
