AWS Blu Age Code Maintainability

Migration and Modernization Blog

This article discusses AWS Blu Age's approach to transforming mainframe COBOL applications into maintainable, modern Java applications. Key highlights include:

  • Generating readable, modular Java code that avoids "JOBOL" (COBOL-like Java code)
  • Implementing code maintainability through:
    • Clear readability and naming conventions
    • Modular project structure
    • Reduced code complexity
    • Improved evolvability
  • Using tools like SonarQube for code quality assurance
  • Enabling easier testing and documentation
  • Supporting future modernization and cloud integration

The goal is to transform monolithic mainframe applications into agile, maintainable Java applications that can be easily understood and evolved by modern developers.
