Case Study: U.S. Federal Agency modernizes mission-critical systems with Astadia

U.S. Federal Agency modernizes 1.5 million daily transactions with Astadia

The U.S. Federal Agency faced the challenge of modernizing a highly complex, mission-critical mainframe system that was difficult to maintain and scale. The legacy environment, running on IBM Z14 hardware with COBOL, Assembler, CICS, and Db2, had escalating costs and a risk of losing key technical expertise. The agency partnered with Astadia to increase scalability and organizational agility by migrating to a cloud-based platform.

Astadia refactored the agency's applications by converting COBOL and Assembler components into Java and migrating data from Db2 to PostgreSQL. Utilizing proprietary tools and a highly automated methodology, Astadia delivered a modern, scalable application built with Java-based microservices for deployment on AWS GovCloud. The results positioned the agency to reduce long-term operational costs, eliminate dependency on specialized mainframe skills, and more easily integrate modern technologies.
