Accelerating Innovation and Transformation of Legacy Applications
The continuous digital revolution calls upon enterprises to abandon the crumbling, almost ready-to-expire legacy systems and replace them with more agile modular applications and database management systems.
New-world programming is an enterprise norm today that delivers cost-efficiency and faster time-to-value. Modern-day applications provide better support for multi-device compatibility, resource reusability, cross-platform functionality, and seamless integration with other business systems.
Leveraging emerging technologies for improved quality, responsiveness, and productivity help outperform the competition in an always-connected digital economy.
Every organization has legacy applications that are mission-critical but need a significant makeover. However, the need to keep up with changing compatibility, higher availability, better compliance, and performance market demands has made these applications expensive and ineffective.
Legacy applications are less scalable, tightly coupled, and less adaptable compared to modern-day apps. This limits the cloud’s solutions, where almost every other modern-day app runs with advanced IT capabilities.
Here are some compelling reasons to consider modernizing your apps.
Many companies have had critical failures with their app modernization efforts since it usually impacts their current operations and the overall underlying system.
Radiant Digital helps you meet business objectives and justify investments with app modernization strategy and support.
We focus on reducing technical complexities, improving resilience, fault tolerance, and replacing obsolete, end-of-life software components with newer technology and a unique approach, including the following steps.
This blog will give you better visibility on why app modernization is so essential to your technology-driven initiatives.
What is App Modernization?
Application modernization is the process of changing, refactoring, remodeling, or modularizing the existing legacy applications to improve their internal architecture, capabilities, design and functional features, technology stack, or code quality.
It involves reviewing the end-to-end current system state using either the top-down or bottom-up approach. It requires a dedicated team of resources, reverse engineer through the business processes, understand and document every integration, system performance bottlenecks, what and why it was developed the way it is today.? The reverse engineering process helps to define and shape the architecture and direction for App modernization.
It is the transition of existing enterprise applications to new approaches like cloud computing, Microservices, and Containerization to achieve the following:
This is done by improving the velocity of new features delivery, exposing the functionality of the existing applications consumed via API by other services, and migrating applications from on-premises to the cloud for optimized performance and better IT strategy.

Key Drivers of App Modernization
While there are many reasons why legacy enterprise applications need a digital makeover, here are some of the most significant ones.
Changing Business Dynamics
There is an increased need to accelerate digital transformation to deliver new capabilities quickly and cost-efficiently. ?Instead of adopting new technologies and business models, if you are stuck with your old software, you are letting new growth opportunities go unnoticed. The first step for businesses that look for innovation is application and process modernization.
Hidden costs of Legacy Applications
Any feature or functionality that is obsolete is an unyielding investment. Operational and maintenance costs represent just the tip of the iceberg. The following hidden fees form the sources of legacy software expenditure.
Refactoring your existing legacy applications provides access to greater functionality at minimal costs that arise due to investments in third-party applications.
Outdated Security?
Security provides IT resilience (e.g., backup, disaster recovery, high availability, and continuity planning) to protect data and ensure continued business operations in the event of a disruption. According to the?HIMSS Cybersecurity Survey , almost 70% of businesses today are still exploiting some legacy apps. Legacy applications are usually less resistant to cyberattacks, harmful programs, and malware because cyber attackers get familiar with the code and its vulnerabilities.
Modernized applications in the cloud provide ubiquitous access to top-of-the-line safety features and quick updates. They collectively secure the environment from external threats and accidental data exposure.
Change Management Hindrances
Legacy systems have large codebases with complex functionalities. Their monolithic nature makes changing or replacing one system module difficult. A small update might create a wave of system conflicts.
Thus, any legacy system changes require time and effort associated with high expenses. Additionally, legacy systems need vast amounts of documentation.
Modernizing legacy apps helps automate change implementation in an agile environment with lesser errors. This reduces time, effort, and cost.
Need for Better Operational Efficiency and Standardization
Using legacy apps in a diverse environment requires standardization to ensure seamless performance. Agile methodologies in app modernization can speed up the provision of IT services by at least 30%. Thus, initiating modernization focusing on continuous delivery helps integrate product development with IT operations with DevOps. App modernization promotes automation and operational transformation to improve team efficiency.
Integration Challenges
Legacy software platforms are seemingly challenging to integrate with third-party APIs to access a few capabilities like user authentication, data sharing, and transactions. A significant amount of custom coding is required for connecting legacy software to a third-party tool or service.
There is also the risk that the final integration won’t work as intended. App modernization makes apps integration-ready by default.

Infrastructure Issues
Legacy systems need a specific technical environment, including hardware, which is more difficult and expensive to maintain. They are usually built to-be-deployed and function optimally over on-premise infrastructure.
This keeps the infrastructure maintenance spending high and lowers performance. Legacy data is scattered across several databases and storage resources. Gathering and systematizing legacy data is thus necessary for space optimization.
Benefits of App Modernization
The following benefits prove that legacy-system modernization is vital to overall business digitization.
App Modernization Market Trends
The growing need for business agility, faster time-to-market, leveraging big data technologies in the connected era, and cloud computing is the significant component of many businesses’ application modernization strategies today. This is driving great opportunities in the services market.
The App Modernization Services in high demand include:
? Application portfolio assessment
? Application re-platforming
? Cloud application migration
? Post-modernization services
? Application integration
? User Interface (UI) modernization
According to Forrester , companies seek “innovative development services for enterprise apps, which will drive adoption (and spending) as companies start tearing apart core business apps and modernize them with innovative analytics, machine learning, IoT, messaging, and database services created in the cloud.”
