What Is a Application Modernization?

Application modernization refers to the process of updating and upgrading legacy software applications to make them more efficient, scalable, and compatible with modern technologies and business needs. The goal of application modernization is to enhance the functionality and performance of existing applications and enable them to meet the evolving needs of users and businesses.

Application modernization can take different forms, depending on the specific goals and requirements of the project. Here are some common approaches to application modernization:

  • Re-platforming: Re-platforming involves moving an application from an older platform, such as a mainframe or legacy system, to a more modern platform, such as the cloud or a virtualized environment.
  • Re-factoring: Re-factoring involves making changes to the code and architecture of an application to improve its performance, scalability, and maintainability.
  • Re-hosting: Re-hosting involves moving an application to a new infrastructure without making any significant changes to its code or architecture.
  • Re-architecting: Re-architecting involves redesigning an application to take advantage of modern technologies, such as microservices, containers, or APIs.
  • Re-building: Re-building involves completely rebuilding an application from scratch using modern programming languages, frameworks, and architectures.

Application modernization can bring many benefits to organizations, such as reduced costs, increased efficiency, enhanced user experience, and improved security and compliance. By modernizing legacy applications, organizations can stay competitive and adapt to the changing business and technological landscape.

How Techonomy helps in Application Modernization

Application modernization is the process of updating legacy applications' internal architecture, platform infrastructure, and/or functionalities. Today, a lot of the conversation about application modernization focuses on monolithic, on-premises apps, which are typically updated and maintained using waterfall development techniques, and how those applications may be integrated into cloud architecture and release patterns, specifically microservices and DevOps.

The advantages of application modernization can typically be summed up as increasing the speed at which new features are delivered, making it possible for other services to consume the functionality of existing applications through APIs, and moving applications from on-premises to the cloud in order to improve application scale and performance as well as long-term data centre and IT strategy.

Usually, the costs and complexity of application modernisation are the biggest obstacles. Applications should not be moved from on-premises to the cloud only for the sake of moving them. In contrast, other applications may gain significantly from replatforming or rearchitecting but are so tightly integrated with current infrastructure and systems that the complexity of modernization may outweigh the advantages.

The secret to application modernization success, like most things, ultimately comes down to strategy and choosing modernization projects where the advantages of cloud, speed, performance, scale, new feature development, etc. are ones that offer the given application a clear path to improved customer experience and ROI.

Why modernize legacy applications?

Monolithic applications, or legacy applications, are frequently. Due to their difficulty in updating and their expensive and challenging scaling, monolithic apps are a good candidate for modernization.

For architectural reasons, monolithic programmes are challenging to update. Given the complexity overhead and integration problems, it is challenging and expensive to add functionality because all of an application's components ship together.

They are difficult and expensive to scale for related reasons. It may be required to scale up the entire programme in order to service the most demanding single component if even one of an app's components is experiencing load and performance issues. This method wastes a significant amount of computation.

Components can be delivered and scaled independently of one another, are smaller and loosely linked, and can be modernised to more closely resemble a microservices architecture. This method is where much of the core value in modernisation may be found, although posing its own set of difficulties.
