COBOL in the 21st Century

In the fast-paced world of technology, where trends fade faster than yesterday’s headlines, few expected a programming language born in the era of punch cards to still be relevant. Yet, here we are, in the 21st century, and COBOL continues to hum quietly beneath the surface, powering the critical infrastructure of major industries. From banking and finance to healthcare and government systems, COBOL’s legacy code silently processes countless transactions, reminding us that sometimes, the classics never truly go out of style.

However, the question isn’t just about relevance; it’s about adaptability. Can this aging giant gracefully navigate the ever-evolving technological landscape? The answer, surprisingly, is a resounding yes. Thanks to continuous modernization efforts and exciting new possibilities, COBOL is not fading into obscurity; it’s undergoing a remarkable transformation.

Why COBOL Still Matters:

There’s a misconception that COBOL is simply “old.” In reality, it’s a mature language with inherent strengths that remain valuable in today’s world. Its precise data handling capabilities, built-in

security features, and vast codebase of mission-critical applications form a critical backbone for countless organizations. Replacing this functionality with modern languages would be a colossal, risky, and often unnecessary endeavor.

So, instead of scrapping, the smart play is modernizing. This strategic approach focuses on adapting existing COBOL systems to meet modern needs and standards, ensuring they remain relevant, secure, and maintainable.

Modernization: More Than Just a Buzzword:

Modernization isn’t a one-size-fits-all solution. Different approaches cater to specific needs:

• Structured COBOL: Bringing order to the chaos. By restructuring existing code, readability, maintainability, and testability improve, making future modifications easier.
• Microservices and APIs: Breaking down the monolith. Wrapping COBOL modules as microservices unlocks the benefits of cloud computing and facilitates integration with modern web APIs.
• Web Services and Mobile Apps: Bridging the gap. Exposing COBOL data and functionality through web services and APIs enables access from modern applications, including mobile apps.
• Model-Driven Modernization: Fast-tracking the journey. Tools that automatically translate COBOL code into modern languages can significantly accelerate the modernization process.

Tools for the Trade:

Thankfully, organizations don’t have to embark on this journey alone. A rich ecosystem of tools empowers COBOL modernization efforts:

• Micro Focus Enterprise Developer: A comprehensive suite for COBOL development, testing, and modernization.
• Fujitsu NetCOBOL: Modernizes applications for deployment on various platforms, including the cloud.
• BMC Helix Apparat: Automated code analysis and remediation for improved security and performance.
• Rocket Software Modernization Platform: Tools for migration, replatforming, and integration of COBOL applications.

Cloud: COBOL’s New Playground:

The cloud revolution has opened exciting possibilities for COBOL. By migrating to platforms like AWS, Azure, or GCP, organizations can enjoy:

• Scalability and Flexibility: Easily adapt to changing demands by scaling resources up or down as needed, eliminating expensive hardware upgrades.
• Enhanced Security: Leverage robust cloud security features and infrastructure to improve overall application security.
• Reduced Costs: Pay-as-you-go models can significantly reduce IT infrastructure costs and improve operational efficiency.
• Modern Development Tools: Access cloud-based development tools and services for agile development and continuous integration/continuous delivery (CI/CD) practices.

From Legacy to Leader: What’s Next for COBOL?

Modernization isn’t the endpoint; it’s just the beginning. Emerging technologies like artificial intelligence (AI) and blockchain offer intriguing possibilities for COBOL’s future. Imagine AI-powered tools that automatically analyze and optimize COBOL code, or blockchain-based solutions that enhance data security and transparency in COBOL applications.

The Human Touch: The Essential Ingredient:

While tools undoubtedly play a crucial role, modernization ultimately hinges on human expertise. Organizations need to invest in upskilling their existing COBOL workforce or attracting new talent with modern COBOL skills, including knowledge of structured programming, web services, and cloud platforms.
