Cloud Migration

Key Points

• Moves workloads into cloud environments
• May involve data, apps, and networking
• Can be phased or lift-and-shift
• Common in modernization projects
• Requires careful operational transitions rather than simple workload copying
• Involves planning, transferring, validating, and stabilizing workloads

Definition

Cloud Migration is the process of moving applications, data, or infrastructure from one environment to a cloud environment or between cloud environments.

Concept

Cloud Migration is used in enterprise IT, application modernization, and infrastructure transformation. It can involve rehosting, refactoring, or staged migration depending on the target architecture and business needs. Cloud migration exists to move workloads into cloud environments or between cloud services, combining infrastructure change with operational transition management.

Explainer

Cloud Migration works by planning, transferring, validating, and stabilizing workloads as they move from source to destination. This may include data replication, application refactoring, network reconfiguration, and cutover steps.

Constraints include compatibility, downtime limits, data transfer speed, identity integration, application dependencies, and testing requirements. Failure modes include data loss, downtime, broken integrations, performance problems, and migration plans that do not account for hidden dependencies.

Tradeoffs involve faster migration versus more risk, lift-and-shift simplicity versus limited optimization, and phased transition versus longer project duration. Cloud migration matters because moving to cloud environments usually requires careful operational transitions rather than just copying workloads. Cross-industry relevance is strong across enterprise IT, software services, and digital transformation.
