The digital revolution has reshaped the IT domain, demanding a shift from outdated legacy systems to agile application modernization. Yet, many organizations still need to grapple with the challenge of navigating this new digital frontier while being anchored by monolithic legacy infrastructure.
Surprisingly, a significant portion of today’s IT infrastructure—31%, according to a recent survey—is still composed of legacy systems. Even more startling is that only 33% of technology in large enterprises has been modernized to meet the demands of the digital age. These aging systems, built for a different era, often lack the flexibility and agility to thrive in the digital domain. They were never designed to support the dynamic, composite applications now essential for business success.
The pandemic has only intensified the urgency for digital transformation. As businesses pivot to adapt to new realities, the need for robust application modernization has become more apparent than ever. But modernization isn’t just about upgrading technology; it’s about reimagining your entire IT infrastructure to support innovation, efficiency, and growth.
What is Application Modernization?
Application modernization is the principle of updating legacy applications’ and modernizing their internal architecture, platform infrastructure, and functionalities. Today, much of the conversation about cloud application modernization centers on monolithic, on-premises applications that are typically updated and maintained using waterfall development processes and how those applications can be adapted to cloud architecture and release patterns, specifically microservices DevOps.
Application modernization roadmap entails consolidating, repurposing, or restructuring old programming or software code to extract additional business value from the existing application and better align it with the needs of the current business environment.
The primary goal of many applications’ IT modernization strategy is to transform monolithic, on-premises systems into cloud-native design and release patterns. In particular, modern application development methods like DevOps and microservices employ waterfall software product modernization development methods instead of onsite maintenance and updating.
This is a crucial stage since fulfilling new business requirements while maintaining the functionality of legacy programs takes a lot of time and resources. Moreover, when software becomes incompatible with modern systems due to age, this problem gets worse.
When and Why Applications Need Modernization
What is application modernization? It’s not a buzzword; it’s the lifeline for organizations determined to stay relevant, resilient, and ready for anything. In a world powered by speed, agility, and digital transformation, outdated systems are the silent killers of progress.
Let’s break it down: legacy systems don’t age; they decay. When they do, the ripple effect touches everything from innovation to customer experience. This is where application modernization becomes more than a tech initiative; it becomes a business priority.
Why It Matters
1) Maintenance is a Minefield
As technologies age, support dwindles. Maintaining legacy code becomes a costly patchwork game without the right application modernization tools.
