Cloud migration is the process of moving applications, data, infrastructure, or business systems into a cloud environment. The source may be an on-premises data center, another cloud, or a legacy hosting platform.
Migration is not only copying servers
A migration can involve rehosting, refactoring, rebuilding, replacing, or retiring systems. Teams must consider security, networking, cost, data, downtime, and application dependencies.
Lift and shift
Lift and shift is one migration style where a workload is moved with minimal redesign. It can be fast, but it may miss deeper cloud benefits.
Cloud migration is a project, not just a file transfer.
