TITLE Modernizing Legacy Systems through Cloud Migration and Enterprise Architecture Patterns
ABSTRACT Legacy systems remain foundational to mission-critical operations across public and private sector organizations, yet they often inhibit scalability, interoperability, and innovation. Research has shown that poorly planned cloud migrations frequently replicate existing technical debt rather than eliminating it [1][2]. This paper presents a structured methodology for modernizing legacy systems through cloud migration, guided by established enterprise architecture patterns. By combining cloud-native principles, API-driven architecture, domain-driven design (DDD), and agile DevOps practices, the proposed approach enables incremental transformation while maintaining system stability. The paper highlights architectural strategies validated by prior research and industry frameworks, offering a practical roadmap for enterprise solution architects and technology leaders.
