Innovative Approaches to Large-Scale Cloud Migration and DevOps Integration

Abstract

The rapid adoption of cloud computing has compelled enterprises to modernize legacy systems and migrate large-scale workloads to distributed cloud environments. However, organizations continue to face critical challenges related to cost management, architectural complexity, security risks, and limited automation during migration. This review examines how DevOps practices—particularly Continuous Integration/Continuous Deployment (CI/CD), containerization, automated testing and Infrastructure as Code (IaC)—can address these challenges and improve migration outcomes. A structured analysis of recent literature, supported by sector-specific case studies from finance, healthcare, manufacturing, and education, highlights the role of DevOps in reducing deployment failures, accelerating release cycles, enhancing system resilience, and lowering operational costs. The findings indicate that DevOps-driven automation not only streamlines migration pipelines but also strengthens security posture, improves resource optimization, and supports large-scale modernization efforts. This paper contributes a consolidated understanding of emerging approaches in cloud migration and proposes a conceptual direction for integrating DevOps pipelines as a foundational enabler for reliable, efficient, and scalable cloud transformation strategies.
