What is Cloud Migration?

The process of moving applications, data, and workloads from on-premises infrastructure to cloud computing environments.

Cloud migration involves transitioning digital assets from local data centers to cloud platforms. Common strategies include rehosting (lift-and-shift), replatforming (lift-and-reshape), refactoring (re-architecting for cloud-native), repurchasing (switching to SaaS), and retiring (decommissioning). Successful migrations require careful planning around data transfer, application compatibility, security, compliance, cost optimization, and staff training. Tools like AWS Migration Hub, Azure Migrate, and Google Cloud Migrate help automate and track the process.
