Mainframe Decommissioning and Cloud Migration Case Study

This case study details the approach taken by a United States government agency to decommission its mainframe case management system within a strict deadline of 12 months. The agency required a scalable software architecture that could integrate with other enterprise applications and facilitate critical data exchange. Peraton's solution involved a three-part strategy: understanding business requirements, re-architecting the application to a modern framework, and implementing DevSecOps best practices. The Peraton team collaborated with government counterparts to analyze COBOL source code and draft user stories. They utilized cloud-native technologies and established a continuous integration/continuous deployment (CI/CD) process to ensure compliance with security practices. The migration to AWS Cloud and the adoption of a microservices architecture improved customer experience and application performance while reducing downtime. The case study outlines the successful completion of the decommissioning objective and the qualitative benefits achieved through the new architecture.
