Cloud migration is the process of moving digital assets—data, applications, and workloads—from on-premises or another environment to cloud computing platforms. It encompasses public cloud, private cloud, and hybrid configurations and can involve IaaS, PaaS, or SaaS services. Migration strategies are commonly described by the six Rs: rehost (lift-and-shift), replatform, refactor, repurchase, retire, and retain, guiding decisions about architecture and investments.

Typical phases include discovery and assessment to inventory assets and dependencies, planning of target architecture and migration sequence, execution using migration tools and automation, validation and cutover, and continuous optimization post-migration. Governance, security, and compliance are integral throughout, with attention to data residency, access controls, and cost management.

Benefits often cited include scalability, improved resilience, potential cost savings, and faster deployment of new capabilities. However, migration can introduce risks such as downtime, data transfer costs, security gaps during transition, vendor lock-in, and complexity of interoperating multiple cloud services.

Common best practices include establishing clear objectives and success criteria, performing dependency mapping, piloting with a small set of workloads, choosing appropriate migration patterns, employing infrastructure as code and automation, and implementing ongoing cost and performance monitoring.

Trends include multi-cloud strategies, containerization and orchestration, serverless computing, data gravity considerations, and increased use of automated migration platforms and AI-assisted analytics.
