Multi-cloud database migration: Strategies for seamless data portability

Asokan, Ellavarasan (2025) Multi-cloud database migration: Strategies for seamless data portability. World Journal of Advanced Research and Reviews, 26 (1). pp. 1396-1404. ISSN 2581-9615

Multi-cloud database migration presents both significant opportunities and complex challenges for enterprises seeking to achieve data portability across AWS, Azure, Google Cloud, and other platforms. This article examines strategies for seamless database migrations in multi-cloud environments, addressing key considerations including cross-cloud data federation through polyglot persistence and virtualization, network optimization via AI-driven traffic management and strategic caching, security implementation through zero-trust architectures, schema conversion through homogenization and automation, and cost management through optimization and workload-based resource allocation. The evolution toward standardization, including the development of vendor-neutral platforms, cloud-native database systems, and sophisticated abstraction layers, promises to reduce migration friction while enabling truly portable data architectures that balance performance, security, and compliance requirements.
