In and Out of Application Modernization | Techniques for Application Modernization

Businesses, both SMEs and large enterprises, are still using their traditionally built mobile applications and are wasting their resources. These mobile apps also render a negative impact on their employees and demotivate them.

Application modernization is the process of optimizing and re-developing the traditionally built mobile apps, and the process also includes modernizing the existing platform, architecture, UI/UX, and more. This process is done by looking for the loopholes in already existing mobile apps.

Before we discuss the strategy of application modernization, let’s discover what application modernization is and what the inherent benefits of the same are.

What is Application modernization?

Application modernization is the technique of updating the older software for newer updated technologies, frameworks, and infrastructures. The process of application modernization is also sometimes referred to as legacy modernization.

When you consider the existing legacy applications, replacement is not always feasible. The process of application modernization is complex and requires specific techniques to achieve successful data integration. Here at Debut Infotech, we define the most specific and best-practice framework for modernization.

Benefits of Application Modernization

According to research by Spiceworks, 64 percent of organizations report that updating legacy systems is a core IT spend driver.

As per research conducted by McKinsey, the four main benefits of application modernization for your enterprise are as mentioned below:

  • IT productivity increases by up to 30 percent as big complexities associated with these projects are removed. In addition to increasing IT productivity, application modernization also helps to automate tedious business processes.
  • Defects and bugs associated with application modernization are applications.
  • The motivation of the current and new employees increases by up to 40 percent, and more talented employees are drawn in to use newer applications. Businesses get the power to align their features and services with growing business needs.
  • The go-to-market process and shipping of new products become faster by up to 60 percent as more modern and optimized [ts2] is made market-ready.
  • With application modernization, business processes can reduce their operational costs by up to 13 percent through modernizing the outdated systems.

The 5 R’s of Application Modernization & Migration

1. Rehost

In this methodology of application modernization, the existing application is lifted from one infrastructure environment and is again re-hosted on a modern and more powerful environment without any redesigning or restructuring of the existing architecture.

The method of Re-hosting an already built application is also referred to as the “Lift & Shift” method and includes Amazon VM Export/Import and VMWare P2V module.

2. Refactor

This approach aligns well with the techniques used in ReHost approach, but with some modifications and enhancements to the core components of the traditional methodology. One typical example of this includes breaking down the existing application into various components such as backend, frontend, and other logging services.

This way managing and optimizing the smaller components becomes much easier and hassle-free. Examples of refactoring include deploying containers and PaaS in the current mobile apps.

3. ReArchitect

The reArchitect technique is kn0wn as one of the most complicated and large-scale application modernization methodologies which encompass a complete overhaul of the existing mobile app framework, and re-imagining the way the application architecture is conceptualized and developed.

In the ReArchitect methodology, cloud-native tools and software are deployed and this translates to more scalability, agility, and enhanced capabilities of the new and modern apps.

4. Rebuild

Re-building refers to the rewriting and re-developing of the entire mobile application as well as preserving the original scope and specifications of the already built infrastructure.

In a way, rebuilding is very similar to reArchitect methodology with a major difference in the actual process. Instead of just remodeling the entire application, in this technique we are re-developing and relaunching the legacy mobile application in a completely new way.

5. Replace

In this technique, we can completely replace the existing mobile app with a new mobile app having a completely new structure, scope, and functionalities. In this model, newer and more robust techniques are deployed for making the modern application more ROI-centric and productive.

One such example of Microsoft Exchange Server with 100 percent cloud-based office 365 is a good example of this application modernization methodology.

6. RePlatform

In the platform theory, the core application structure is not altered but the overall functionalities and user experience are optimized and customized as per the business objectives.

The technique is also referred to as the “lift-tinker-and-shift” model, and examples include WebLogic to Apache Tomcat migration or using AWS Elastic Beanstalk to deploy an application.

Final thoughts

Application modernization is a great business priority but at the same time is a very daunting task. Many businesses are already investing in application modernization techniques and are moving a step ahead of you in this competition. We, at Debut Infotech, believe that this is the right time to invest in application modernization to speed up the entire process.
