Large Language Models Simplifying App Modernization

Summary: The video discusses the challenges faced by COBOL developers managing a complex monolithic application. It highlights how large language models can enhance understanding and maintenance of the application by providing documentation and facilitating the refactoring process, ultimately transitioning from a monolith to segmented services that are easier to manage and integrate.

Keypoints:

• COBOL developers face difficulties maintaining and understanding monolithic applications with numerous files and a large database.
• Large language models can aid in adding documentation to the existing COBOL code, making it easier to comprehend.
• Refactoring Assistant can be used to extract parts of the monolithic application and transform them into individual services.
• By segmenting the application into services (e.g., customer data), developers can improve manageability and maintenance.
• The refactored services can be exposed via an API, facilitating better integration within the company.
• Utilizing large language models enhances daily tasks for developers by streamlining code understanding and maintenance processes.
• COBOL developers are encouraged to leverage these technologies to simplify their workloads and increase business value.
