Real-World Strategies for Secure, Scalable, and Cost-Optimized Cloud Migrations

As organisations scale their operations both on-premise and in the cloud, they face increasingly complex challenges in securely and efficiently migrating their processes at scale and within budget. Migrating to the cloud is no longer merely a technological choice, but a strategic business transformation. Successful implementation requires careful consideration of risk management, performance evaluation, compliance requirements, and budgetary constraints. Yet, despite the wide availability of migration tools and techniques, a disconnect remains between the chosen migration strategies and the desired outcomes in terms of performance, security, and cost-efficiency. This review has presented a combined theoretical framework that can be applied to guide the movement of the cloud across a broad spectrum of industries and within various organisations. It summarizes the current research findings, introduces the most prominent pitfalls, and proposes the feasible options that the new frontiers in the evolution of automation, orchestration, and cloud-native architecture open. Other post-migration optimization practices and other governance systems, which are central to the long-term sustainability, are also discussed. A perspective study of future trends and enablers of cloud migration in the future is the final section of the paper.
