Using Mendix to Modernize your Legacy App

The Application Modernization Market registered USD 12,944.73 million in revenues in 2021 and is projected to grow at a CAGR of 18.70% to reach USD 60,554.94 million by 2030. The market is being driven by increasing adoption of cloud computing and big data technology. But the decision to migrate can be an agonizing one. Often, legacy systems might be still delivering the expected outcomes. The challenge lies in its inability to cope with the scalability and flexibility needs of the modern enterprise to automate processes and build customer portals.

Monolithic architecture has unorganized code that makes updating difficult and time-consuming for developers. In modern times, where businesses need to constantly evolve their systems to meet their customers’ needs, legacy systems cannot evolve as quickly. Even making small changes or updating just one part of the application can be difficult.

From Monolithic to Microservices Using Low-Code

Migrating the legacy system to a modern system is challenging for another reason. Since businesses are still using these systems for mission-critical operations, any disruption will affect business continuity and operations. Therefore, replacing the entire system with a modern one may be risky.

The incremental move of legacy applications to a modern architecture using microservices can enable pacing to ensure minimum disruption with optimal performance. Furthermore, low-code development platforms such as Mendix can facilitate easy migration based on the unique needs of businesses.

With low-code development, businesses can create a streamlined path facilitating visualization and collaboration. Low code reduces the dependence on the IT team as even non-technical users can use drag and drop to build apps efficiently and increase the business value of the app.

Mendix’s low-code platform allows businesses to decentralize and simplify the system, improve the efficiency of the applications, and become more agile to meet changing business and user needs. This increases the resiliency and also enables the updation of individual services without impacting the entire system. Mendix low-code also allows the IT and business teams to speak a common language, thereby simplifying the process of app development. With microservices, organizational complexity can be reduced as smaller groups of stakeholders can be assigned specific responsibilities.

1. What does modernizing legacy applications and systems involve?

The best approach to legacy modernization depends on the individual business’s maturity level, challenges, and goals. Therefore, the first step involves assessing the current legacy systems, defining goals, identifying gaps, and creating a modernization roadmap. This will help determine which apps can be encapsulated, and which need to be rehosted, re-platformed, refactored, rearchitected, rebuilt, or replaced.
