Application modernization is a solution to accelerate the digital transformation journey of any organization. The market presents an ever-changing scenario that requires organizations to undergo a shift in their processes and workflows. Most organizations have their applications in an on-premise environment, thus creating bottlenecks like security vulnerability, reduced productivity, reduced scope of innovation, and ineffective data management. Application modernization is the solution to all these. 

But to have a successful app modernization journey, there are best practices to apply so that the process is seamless and successful. In this article, we discuss a few of the best practices you can adopt for a successful app modernization journey.

Below are a few best practices for a successful app modernization journey:

To gauge the success of an initiative, align the modernization journey with your business and I.T. goals. Better agility and faster time to market can be used as  measurable objectives to show progress.

You must identify the most critical and highest-priority applications to start the goal-setting process. Then analysis of how scalability, reliability, and better performance should be done to gauge how they will benefit your business.

The six popular approaches of modernization are Rehost, Refactor, Re-platform, Re Architect, Replace, and Rebuild. To make the most out of the modernization process you can start with any of the approaches. For example, you can decide to first Re-host the application in the cloud without changing the software code. Then you can re-platform it with an efficient cloud-based solution. You can then Refactor a high-priority application of your choice and take advantage of additional cloud technologies. All these are dependent on the approach that will best suit your application type.

Consider project goals, assignments, tasks, and start and finish time to create a project timeline. Communicate with the project team on the priorities, and project tasks and then track the progress based on your objectives. There are tools and software you can use to plan the app modernization timelines.

Allows an organization to forecast time, what they need to finish the project, and get the correct modernization cost estimate.

This method sizes the software work product functionally in terms of what the user requests and receives.

Documenting will serve as a vital tool for future maintenance and a foundation for later transformations. Ensure you document every detail since the initiation of the job. These may include files and programs you have used during the development process. You also record any changes introduced to the process. Detailed documentation is critical when you want to digitally transform aging applications.

To speed up the delivery cycle of the software and offer value to your organization in a short time, automation has to be adopted in the modernization plan.

This can be done by:

After streamlining the App modernization journey, the next thing should be measuring the performance of the modernization process through performance metrics like response time, throughput, memory usage, and CPU utilization. Tracking them will help identify performance issues and bottlenecks. This will also enable you to track in real-time application’s performance.

To deploy new applications, you will require transformed skill sets across the company that will drive and sustain the changes. An example of a staffing hierarchy can include:

Conclusion

App modernization is not an overnight process. It requires meticulous planning and to be able to achieve it successfully you have to apply some tried and tested best practices.
