A National Railroad Operator (Agency) hosted several custom applications on a zOS mainframe based legacy system with a 20+ year old code base.
Attrition of SMEs running and maintaining these applications, limited knowledge and documentation of these applications, and proportionally higher operational cost created significant risks to business continuity and limited the agency’s ability to meet its mission and serve customers cost effectively.
They had struggled with their modernization initiatives over the years as they executed an opportunistic approach to modernization lacking in overall vision, integrated planning and organization-wide coordination.
Solution
Infosys Public Services (IPS) had been maintaining the agency’s systems in a managed services model and had developed a good understanding of the application portfolio.
Building upon this insight, IPS conducted a strategic assessment of the agency’s modernization priorities, organizational capabilities, and current legacy footprint to develop a data-driven blueprint and modernization roadmap for re-engineering their mainframe applications and migrating them to the cloud.
IPS navigated zero disruption modernization of the mainframe system, reducing TCO by nearly 30%, improving system performance and reducing operational risk.
