What are the types of cloud migration?

Rehosting (Lift and Shift) – This involves simply moving applications to the cloud with minimal changes, essentially just relocating the existing infrastructure to the cloud environment.

Relocating (Lift and Optimize) – In this approach, you move applications to the cloud without major modifications, but then optimize specific components to take advantage of cloud-based services and capabilities.

Refactoring – This strategy entails extensively rearchitecting applications to fully leverage cloud-native features and functionality, such as microservices and managed services.

Replatforming (Lift, Tinker, Shift) – A middle-ground approach where you make some optimizations to the application to utilize advanced cloud features, but not to the same extent as a full refactoring.

Repurchasing – Replacing existing software licenses and applications with cloud-based alternatives or software-as-a-service (SaaS) offerings.

Retiring – Decommissioning outdated or redundant assets that are no longer required, allowing the organization to focus resources on more critical workloads.

Retaining (Revisiting) – Holding off on migration for certain applications or workloads, and periodically reassessing them to determine the appropriate time for cloud migration.

The ideal migration strategy will depend on factors like business needs, technical constraints, and the organization’s desired outcomes from the cloud migration initiative. Understanding these different approaches can guide a successful cloud adoption process.
