For decades, COBOL (Common Business Oriented Language) has been the silent backbone of the financial, banking, insurance, and government sectors. It is the unsung hero behind trillions of dollars in daily transactions, ensuring ATM withdrawals, payroll processing, and tax calculations run smoothly. Despite its age—COBOL was born in 1959—it remains highly relevant in 2025, defying predictions of its demise. But why? And more importantly, how is it evolving to remain indispensable?
A Legacy that Refuses to Die
COBOL’s endurance is not accidental. The language was designed to be readable, maintainable, and robust, ensuring business processes remain functional and reliable for decades. Unlike trendier languages that come and go, COBOL systems have been running stably for over half a century. This stability, however, has led to a paradox: while businesses rely on COBOL, the talent pool has been shrinking, creating a critical skills gap.
As a result, organizations that depend on COBOL are now scrambling to modernize while keeping their legacy systems intact. They recognize that simply replacing COBOL with newer languages is neither feasible nor practical. Instead, businesses are breathing new life into COBOL by integrating it with modern technologies.
The Rise of COBOL Modernization
COBOL modernization in 2025 is not about rewriting everything in Java or Python. Instead, it is about enhancing existing COBOL applications with modern capabilities. Here are some key trends fueling COBOL’s resurgence:
1. Cloud Migration & COBOL-as-a-Service
Gone are the days when COBOL programs ran exclusively on massive mainframes housed in temperature-controlled rooms. Many organizations have successfully migrated their COBOL workloads to the cloud, leveraging platforms like AWS Mainframe Modernization, Google Cloud’s Dual Run, and Microsoft’s Azure Mainframe Migration solutions.
Cloud platforms now support COBOL-as-a-Service, allowing businesses to run COBOL applications seamlessly without being tied to aging on-premise infrastructure. This approach ensures performance improvements while maintaining compatibility with existing business logic.
2. API Enablement: COBOL Meets the Web
COBOL applications, traditionally monolithic, are now being broken into modular services through APIs. With tools like Micro Focus Enterprise Suite and IBM’s z/OS Connect, organizations can expose COBOL programs as RESTful APIs, allowing modern front-end applications and mobile apps to interact with them effortlessly.
For example, a COBOL-based banking system can now provide real-time customer balance inquiries via a mobile app by integrating with an API layer. This removes the perception that COBOL is a relic of the past and transforms it into a flexible component of modern IT ecosystems.
3. Integration with DevOps & Git-Based Version Control
One of COBOL’s biggest drawbacks was its reliance on traditional waterfall development methodologies. That is changing. Companies are integrating COBOL with DevOps pipelines, allowing for continuous integration and deployment (CI/CD).
In 2025, COBOL source code is increasingly managed using Git-based repositories rather than archaic version control systems like Endevor. This shift enables developers to use familiar tools such as Jenkins, GitHub Actions, and Docker to automate COBOL deployments, accelerating software delivery.
4. COBOL Meets AI: Automated Code Refactoring
The marriage of COBOL and artificial intelligence is one of the most exciting developments in modernization. AI-driven tools such as IBM Watson, OpenText (Micro Focus) AI-powered analyzers, and Google’s Code Insight are helping organizations analyze, document, and refactor COBOL codebases automatically.
A large bank, for instance, might use AI to scan millions of lines of COBOL code to detect inefficiencies, suggest optimizations, and convert redundant sections into microservices. This reduces reliance on deep COBOL expertise while making the codebase easier to maintain.
5. COBOL’s Role in Blockchain and FinTech
COBOL has found a surprising new ally in blockchain. As financial institutions explore blockchain for secure transactions, COBOL applications are being integrated into smart contracts and distributed ledger systems.
A perfect example is how some banks use COBOL to validate and process blockchain-based loan agreements, ensuring seamless compatibility between legacy financial records and decentralized finance (DeFi) applications.
COBOL Talent Revival: A Renaissance for Developers
The notion that “COBOL developers are all retiring” has driven companies to take proactive measures in revitalizing COBOL talent. In 2025, we are witnessing:
- University Courses & Certifications: Institutions like MIT, NYU, and the University of Illinois now offer COBOL programming courses alongside Python and Java.
- COBOL Bootcamps: Companies like IBM and Micro Focus sponsor coding bootcamps for young developers to learn COBOL, ensuring a steady stream of talent.
- Open-Source COBOL: Open-source projects like GnuCOBOL have made COBOL accessible to a wider audience, allowing new developers to experiment with COBOL without needing access to expensive mainframes.
This renewed interest means that being a COBOL programmer in 2025 is not just about maintaining legacy systems—it’s about innovating with them.
Debunking Myths: COBOL’s Future is NOT in Jeopardy
Despite its resurgence, COBOL is still plagued by misconceptions. Let’s address a few:
Myth 1: COBOL is Obsolete
Reality: COBOL processes over 90% of financial transactions worldwide. If it were obsolete, banks and governments would have collapsed long ago.Myth 2: COBOL Can’t Work with Modern Tech
Reality: With cloud deployment, APIs, AI-assisted development, and integration with DevOps, COBOL is more connected than ever.Myth 3: COBOL Jobs Are Dying
Reality: The demand for COBOL developers has never been higher. In fact, the skills gap means COBOL programmers often command salaries comparable to, or even higher than, Java and Python developers.Conclusion: COBOL’s Best Days Are Not Behind It
In 2025, COBOL modernization is no longer just a legacy concept—it is a bridge between the past and the future of enterprise computing. Its reliability, coupled with new modernization strategies, ensures that businesses can continue leveraging their mission-critical COBOL applications while embracing cutting-edge technologies.
Far from being a relic, COBOL is now a vital player in digital transformation, proving that age is just a number when it comes to programming languages. So the next time someone asks, “Is COBOL still relevant?”—the answer is a resounding YES, and it’s only getting stronger.
If you’re in the tech industry, learning COBOL modernization in 2025 might just be one of the smartest career moves you can make. After all, some classics never go out of style—they just get better with time.
