From Monolith to Microservices a Jboss and Tomcat Migration Guide for Cloud Computing

Enterprises running monolithic Java applications on JBoss and Tomcat face increasing challenges in scalability, maintainability, and integration with cloud-native technologies. Microservices architecture offers a modular, flexible alternative that enables independent deployment, improved fault isolation, and operational agility. This review examines strategies for migrating monolithic JBoss and Tomcat applications to microservices, covering code refactoring, containerization, middleware integration, and orchestration in hybrid and cloud environments. It highlights automation through CI/CD pipelines, security and compliance considerations, and monitoring for performance optimization. Case studies from both large enterprises and mid-sized organizations demonstrate practical applications, lessons learned, and business impacts, including operational efficiency, cost optimization, and accelerated innovation. Emerging trends, such as serverless computing, AI-driven DevOps, and evolving middleware ecosystems, are discussed to provide guidance for organizations seeking sustainable and scalable modernization. This article serves as a comprehensive roadmap for IT architects, developers, and enterprise decision-makers pursuing microservices migration and cloud readiness.
