App Modernization

Why should you update your legacy application?

To successfully migrate from traditional to digital, you must invest in the necessary tools and platforms.

Organizational assets are transformed through app modernization to adapt, optimize, and integrate with current digital software and cloud infrastructures. It enables a company to safeguard its software investments and refresh its software portfolio in order to develop new applications that drive insights from data, accelerate application development to get new products, services, or capabilities to market faster, and improve personalized, relevant, and engaging customer experiences.

Enterprises are increasingly focusing on application modernization.

Why? Because executives are under greater pressure to innovate. Among the causes are digital changes, distant labor, and rising client demands. These forces affect every business. To flourish, businesses must develop, which is why so many companies choose digital transformation.

When companies upgrade their apps, they create new processes and the infrastructure to support them. A solid app modernization plan may lower the number of resources required to run an app, boost deployment frequency and dependability, improve uptime and robustness, and more. By upgrading business processes, lowering maintenance costs, and making data more available, app modernization empowers enterprises to accelerate innovation and get to market faster.

What are the most typical forms of app modernization?

The following are the most prevalent ways of application modernization:

Rehosting: Rehosting, often known as “lift and shift,” is moving servers or software from an on-premises environment to a public cloud architecture. Rehosting is the normal solution for businesses who are just beginning their modernization journey. This option does not necessitate any code, feature, or function changes. Data is transferred to the cloud while business logic is kept.

Refactoring: This method of application modernization comprises retooling major portions of a legacy program’s underlying code to make it perform better in a new environment, generally the cloud. It aids in the reduction of technical debt while also improving nonfunctional qualities.

Replatforming: Similar to rehosting and refactoring, replatforming transfers applications that are already in the cloud to a new cloud environment without affecting the application’s functionality. Upgrading a program to run with a cloud-native managed database, altering the operating system(s) or middleware it will use, or containerizing apps are all examples of replatforming. Replatforming allows businesses to boost scalability and developer efficiency.

Replacing: When a program is no longer required in a cloud environment, decommissioning it is a viable option. Limited value, capabilities replicated elsewhere in the environment, or it is more cost-effective to replace an application than to move it are all reasons for replacing an application.


moves the application to a more modern environment to create benefits such as cost savings, performance gains, or ease of operations.


moves the application and modifies the infrastructure it uses to generate additional benefits such as time and resource savings.


involves re-architecing the application to take advantage of modern cloud services, architectures, technologies to fundamentally improve application quality and performance and enable the rapid delivery of innovative new features.

What are the most important technologies for app modernization?

The following technologies are essential for application modernization:

Cloud Computing: Cloud computing is assisting and fueling an expanding number of digital transformation activities, including application modernization. The cloud is undeniably the major destination for application migration efforts today. Public cloud platforms, private clouds, and hybrid clouds are all included.

Containers: For strategic contemporary application delivery, software containers and container management technologies, particularly Kubernetes, have fast become industry standards. With enterprises deploying a diverse variety of infrastructure across numerous clouds and operating systems, it’s critical that applications stay portable and efficient across many locations.

Microservices: Decoupling distinct components of a program into smaller, discrete bits that may be deployed, updated, and managed independently is the goal of microservices.

Orchestration and Automation: Orchestration refers to the automation of many of the operational processes connected with containers, such as deployment, scaling, and networking, in software development.

What are the most important technologies for app modernization?

Consider the following patterns as you plan your application modernization efforts:

Multi-cloud environments: Multi-cloud refers to the usage of several public cloud service providers for virtual data storage or processing capacity, with or without any existing private cloud or on-premises infrastructure. According to Gartner, multi-cloud strategies are increasingly a question of when rather than if, with many enterprises concentrating 70% of their cloud portfolio with one provider and diversifying the remaining 30%. Read one of our most recent blog entries for additional information on multi-cloud setups.

Hybrid-cloud environments: The usage of public cloud in conjunction with private cloud and on-premises infrastructure is known as hybrid cloud. According to Forrester, 77 percent of business global infrastructure decision makers who are planning, installing, or upgrading cloud say they are in a hybrid-cloud environment since data is currently kept on-premises data centers.

Containers and orchestration: Containers and orchestration are frequently used to package, deploy, and manage applications and workloads. While a classic app may be containerized, containers are seen to be the best match for a more decoupled approach to development and operations (i.e. microservices).

Replacing: When a program is no longer required in a cloud environment, decommissioning it is a viable option. Limited value, capabilities replicated elsewhere in the environment, or it is more cost-effective to replace an application than to move it are all reasons for replacing an application.

For years, businesses have been updating and transferring applications from aging on-premises systems to the cloud. However, it is not always simple.

Legacy technologies typically imply legacy knowledge as well as custom-built procedures, databases, and solutions that are prone to failure and cause unneeded downtime. Moving these legacy apps to the cloud necessitates careful preparation and the selection of a service provider that can satisfy your company’s requirements.

When it comes to modernization and migration projects, you should:

  • Work to bridge the gap between applications and infrastructure with seamless delivery and team cooperation.
  • Consider public, private, and hybrid cloud solutions.
  • Recognize that you may require many service providers, especially if you’re considering a hybrid cloud strategy.
