Modernizing Legacy Systems: A Journey to Kubernetes-Based Microservices (Published)
The modernization of legacy systems through containerization and orchestration with Kubernetes represents a transformative approach to addressing limitations in traditional monolithic architectures. This comprehensive journey encompasses architectural redesign, technological upgrades, and operational transformation to meet current business demands for agility, scalability, and innovation. The transition from tightly coupled monoliths to loosely coupled microservices enables organizations to develop, deploy, and scale components independently while improving fault isolation and resource utilization. Kubernetes serves as a foundational platform for this transformation, providing declarative configuration, self-healing capabilities, and sophisticated traffic management that collectively address traditional limitations. The modernization process requires systematic assessment frameworks, strategic decision-making between incremental and complete transformation approaches, and implementation of essential patterns including Domain-Driven Design for service decomposition and Infrastructure-as-Code for operational automation. Organizations implementing these changes experience significant improvements across operational efficiency, development velocity, and business agility dimensions. Despite implementation challenges, the resulting architectural paradigm delivers substantial benefits including enhanced reliability, improved resource utilization, and accelerated innovation cycles that position organizations for sustained competitive advantage in rapidly evolving digital environments.

How GenAI Agents Are Transforming Legacy Application Modernization (Published)
This article explores how Generative AI (GenAI) is revolutionizing legacy application modernization in enterprise environments. Legacy systems, with their outdated technologies and rigid architectures, represent significant technical debt and maintenance burdens for organizations. GenAI-powered agents are emerging as transformative tools that can analyze complex codebases, discover implicit knowledge, recommend customized modernization strategies, and automate code transformation. The article examines core capabilities of these AI agents, including automated code analysis, intelligent strategy formulation, code transformation, and API generation. It presents implementation approaches across assessment, execution, and governance phases, supported by case studies from financial services, healthcare, and manufacturing sectors that demonstrate substantial improvements in modernization speed, cost, and outcomes. As these technologies continue to evolve, they promise to fundamentally reimagine how organizations approach technical debt and enable more adaptive, innovative technology landscapes
