Application Modernization – Bring New Life to Legacy Systems

Some things get better with the age, or increase in value over time. With IT systems, however, it is the other way. The older the systems are, the more likely they will need to be updated as requirements change or new features are added. As systems age, it is also possible they become more costly, as well as tough to support and maintain. Thus, the need of platform modernization needs to be taken seriously by organizations around the world.

The legacy applications/systems deeply rooted in the organization’s value chain contain valuable data and support core business functions that are essential for digital business initiatives. Alongside the quest to build newer Cloud-native applications, application leaders must also undertake initiatives to modernize their legacy applications to enable interoperability. In other words, there is an opportunity to overhaul the entire application (and not just parts of the code) to take advantage of new application architectures and application access.

Modernization of core business applications/systems has always been around but in the recent past, customer needs have become a priority. Application modernization are no more initiatives focusing on only software and hardware but also involve intra – and inter- business unit processes. This is because today, customers play an instrumental role in driving technology advancement and modernization at a fast pace. Application development, upgrade and operations approaches would therefore require support and training for the staff involved on not just technology but also on the changing industry landscape.

What exactly is Application Modernization?

Legacy application modernization is a plan intended to produce new business value from current aging applications by modernizing them with up-to-date features and capabilities. By migrating your legacy applications, you can embrace the most recent functionalities that align with your business requirements.

The approach to modernization depends on the health of each component of the application, as dictated by business fit, business value, and agility.

The major variables while assessing the health of the whole application are:

  • Application Modernizatione. whether the application needs to acquire a new functionality
  • Process Modernizatione. the methods of application access, securities would need to change
  • Infrastructure Modernizatione. the deployment environment where the application runs would need to change

Once the organization decides to go ahead with the legacy application modernization, there can be huge benefits. The benefits of modernization are often viewed through one of two lenses: operational improvement or competitive differentiation. Let us have a look at some of the benefits:

Cost Effectiveness

Maintaining legacy IT systems is extremely costly. With modernization, you can re-architect your legacy code with modern open-source languages. This helps you reduce the cost of having highly capable developers maintain code that few can work with, while also reducing application incidents overall.


Legacy systems minimize a business’ capacity to form new features and services. Instead, most allot a team to break-fix & manage without a plan for the future.

You can effortlessly overcome these restrictions by bringing your legacy software to the Cloud by rolling out microservices and containerization, which also give your company the ability to add new features and functionality.

Effortless Maintenance

New age applications are less complex and highly flexible, as compared to localized and monolithic legacy applications.

Applications operating in Cloud-based systems offer greater mobility and can be accessed and maintained from anywhere. It is easy to maintain automated processes of well-integrated applications that re-use code.


Modernizing your application is the key to your digital transformation success. Application Modernization allows organizations to transform time-tested legacy applications to newer technologies and architecture to deliver greater business value. Modernizing software products can be a long journey, depending on your needs. Whether you want incremental transformations or a complete metamorphosis of your digital journey, it is essential to keep the product modernization vision at the core of your business strategy.
