We live in a time when technology trends appear and become outdated in months. To miss these changes means to become outdated and less competitive. Organizations must keep up to match users’ needs and the market’s requirements.

When it comes to applications, they must be timely updated, trendy, and user-oriented. As well as secure and easy to maintain. And it’s better when they bring more profit and require fewer resources for maintenance. It’s relevant for businesses of any size operating in any field.

You can reach these goals with app modernization. In the case of enterprises, the apps are more complicated and tied to each other. These apps’ modernization process has its peculiarities.

In this article, we use our expertise in enterprise application modernization consulting and cover all the essentials. You’ll learn its advantages, concepts, practices, and procedures.

What is enterprise application modernization?

Enterprise app modernization is the process of updating the legacy application. You can change its architecture, design, framework, language, features, or everything simultaneously. The mission is to make the app competitive and able to meet current and future business goals.

The most popular modernization strategy is migrating apps and data to cloud platforms. A more complex approach is architecture modernization. You might also opt for UX improvement or integrating the app with other systems. Modernization can also involve replacing legacy systems with applications. It doesn’t replace your whole system but applies the latest technologies to improve it.

The most prominent outcome of enterprise app modernization is improved functionality. It also reduces maintenance costs, increases scalability, and enhances security. Organizations get stronger market positions and better meet their customers’ needs.

Benefits of enterprise application modernization

When it comes to enterprise apps, modernization might be time and resource-consuming. Yet, its benefits make it worth the effort. Let’s look at these benefits in more detail:

Improved agility: Legacy systems lack flexibility and adaptability. When new business goals appear or the market changes, they can’t fully handle it. App modernization helps to improve adaptability and make your apps more responsive.

Better customer experiences: Modern apps are more user-oriented and provide better services to end users. Modernization improves response time and considers market needs, using chatbots, social media, and email requests.

Cost reduction: Maintenance of monolith applications is expensive. When you perform a tiny action, it involves the entire architecture. Modernized apps work differently, and that’s why they are less costly.

Improved efficiency and productivity: Modernizing your apps improves the entire organization’s efficiency. It facilitates approaches and processes, reduces operational time, and encourages updates and service improvements. Cloud services, for example, help to automate processes and cut human interactions.

Improved security: Legacy systems may not meet the latest security requirements. App modernization is the only way to solve this problem.

Why is enterprise application modernization important?

The proper application modernization strategy opens new opportunities for your business. Here are the main arguments in its favor:

Faster time to market. With container orchestration platforms, microservices architecture, and DevOps practices, you release your app faster and win your place on the market.

Quick implementation of new features. Since you don’t have to change the entire architecture to make changes, you can update your systems more frequently. It also allows for applying user feedback faster and achieving a better user experience.

A future-ready platform. Cloud-native architecture helps automate many processes and frees time for action, requiring more human involvement. It improves communication and teamwork. Container management system enhances security and data management.

How to modernize an enterprise app?

There are various approaches to enterprise app modernization. The choice depends on your capabilities, legacy app characteristics, and business goals. Here are some of the best ways to modernize your app:

  • Using low code development tools
  • Including APIs to extend legacy systems
  • Replacing the legacy systems with SaaS apps
  • Building new apps through microservices
  • Reaching a golden mine among traditional, hybrid, and cloud-native applications
  • Integration with continuous deployment tools and processes such as DevOps
  • Using Software-Defined Infrastructure — technologies with a minimal level of human involvement

Enterprise application modernization: Best practices

A key to better performance is a well-chosen modernization strategy. It also helps to reach alignment with your business goals. The most popular practices are:

Microservices approach. The microservices-based environment treats each process as a separate service. It becomes easier to update, scale, or change the process as it has its logic and database. As a result, your apps become more agile and scalable.

Modern development methodologies. Agile and DevOps are prevalent approaches. They allow for continuous development, testing, and deployment. They significantly speed up the modernization.

Cloud services. You examine your data and workflows and define those able for cloud migration, getting access to all the benefits of cloud. Then, you consider how your on-premise apps and cloud ones will communicate.

Tracking performance metrics. Metrics help you follow how your modernized apps perform. You can control the code quality and the entire infrastructure. It applies to every part, from the cloud to databases and networks. This way, you can identify problems at an early stage.

User concerns elimination. Let your users know and understand the importance of modernizing the app and what they will get after. Train them to use the apps and easily navigate the changed structure.

Training employees. Modernizing a legacy application involves learning new technologies and methodologies. Provide adequate employee training to ensure they can effectively use the new system. Embedded security at every stage. Early identification of security challenges in legacy systems is the key to protecting your business. Consider strong access controls and data encryption.

Key technologies for enterprise application modernization in 2023

Enterprise app modernization is a complex and lengthy process that includes various technologies. Among the key ones are:
