How to Modernize applications on Cloud

Flentas Tech 3rd March 2022 - 4 mins read

As we all know, the field of Information and Technology is constantly undergoing evolution and is changing the shape of business in India. An application that seems new today might not be the same after some time. However, organizations can't develop a new application to meet modern needs. IT companies that depend on legacy applications often encounter hurdles like compatibility issues, undesired maintenance costs, etc. This is where the modernization of applications comes into play—application modernization updates older software for newer computing approaches, languages, frameworks, and infrastructure platforms. Modernization enables organizations to realize the much-needed flexibility and agility to address imperative business requirements and future opportunities.

Importance and Need of Application Modernization

Most companies have significant investment in their existing applications from both financial and operational standpoints. Returning these legacy applications and starting over again proves costly and has other issues. Therefore application modernization is the most effective way for many enterprises to realize the advantage of newer software platforms, tools, architectures, and frameworks. Application modernization helps organizations make the most of digital technologies, including Artificial Intelligence, Big Data, and the Cloud. It enables you to build an IT ecosystem based on the current market and have a flexible foundation needed for future innovations.

Windows applications on the Cloud

The main challenge for windows applications is how to transform them to meet the needs of today's users without significant expenses and operational disruption. Cloud applications are agile, scalable, easy-to-use, and cost-saving and make global deployment and access easy. Therefore, modernization of applications on the Cloud is the need of the hour, and hence many organizations are adopting this practice. For cloud modernization, you have to determine which cloud environment is best for you and a strategy best suited to implement your application modernization.

How to modernize applications on Cloud

When people discuss the modernization of applications, they refer to migrating traditional applications to run in modern cloud environments. They include public and private cloud platforms and hybrid cloud platforms (public and private cloud platforms integrated with the on-premises environment). Methods used in application modernization are as follows:

  • Lift and Shift: This method is also known as Rehosting. An existing application had moved from a legacy environment to a public cloud platform. In this, you are essentially moving the application as it is with little or no change to the core architecture
  • Containers: Containers are cloud-centric methods for packaging, deploying, and operating applications and workloads. Containerization includes greater scalability, portability, and efficiency suited for cloud infrastructure
  • Refactoring means taking a legacy application and retooling significant chunks of its underlying code to make it run efficiently in a cloud infrastructure
  • Microservices: Instead of building and operating an application as a complete codebase known as a Monolith, you decouple different components into smaller discrete pieces deployed, managed, and updated independently. Microservices maximize the benefits of cloud-native infrastructure and tools

Benefits of Application Modernization

  • Improved flexibility, efficiency, and agility
  • Enhanced security
  • Improved customer experience
  • Reduced costs and increase in revenue systems
  • Ability to create new features and services


Application modernization reduces the resources to run an application, increases its deployment reliability, and improves its resiliency. As a result, application modernization is a common feature in an enterprise's digital transformation.
