Cloud Migration Strategies#
A company does not “migrate to the cloud” – it migrates dozens or hundreds of applications, each with different characteristics, dependencies, and risk profiles. The 7 Rs framework provides vocabulary for per-workload decisions, but selecting the right R requires understanding the application, its dependencies, and the organization’s tolerance for change.
The 7 Rs#
Rehost (Lift and Shift)#
Move the application to cloud infrastructure with minimal changes. A VM on-premises becomes an EC2 instance. OS, application code, and configuration remain the same.
