Abstract :

Mainframe systems remain the backbone of critical industries such as banking, healthcare, and government, handling vast amounts of transactional data with unmatched reliability. However, traditional mainframe software delivery methods—often manual and sequential—lag behind modern DevOps practices, creating bottlenecks in agility, deployment speed, and innovation. This research explores the integration of DevOps, Continuous Integration (CI), and Continuous Deployment (CD) into mainframe environments to bridge this gap. By analyzing challenges such as legacy architectures, cultural resistance, and compliance constraints, we propose a structured Mainframe DevOps Modernization Framework that incorporates toolchain modernization, automated testing, and deployment strategies like blue-green and canary releases. Case studies and industry surveys demonstrate that DevOps adoption can reduce deployment times by up to 60% while improving code quality by 40%. The study also highlights future research directions, including AI-driven automation, Mainframe-as-a-Service (MFaaS), and quantum computing’s potential impact. This work provides actionable insights for organizations seeking to modernize legacy mainframe systems while maintaining their stability, security, and scalability in a rapidly evolving digital landscape.
