What is a cloud migration strategy? Process and steps

A cloud migration strategy involves creating a comprehensive plan to transition applications, data, and infrastructure from on-premises systems or existing cloud environments to a target cloud environment, using the 6 R's framework (Rehost, Replatform, Refactor, Repurchase, Retire, Retain) to determine the best approach for each workload. The strategy encompasses assessment of the current environment, prioritization of workloads, selection of migration approaches, cloud provider selection, and post-migration operations, ensuring efficient sequencing, risk management, and downtime minimization. Common challenges during migration include cost overruns, undiscovered application dependencies, performance issues, and security gaps, all of which can be mitigated by thorough planning, continuous monitoring, and skill enhancement. Platforms like Northflank help reduce operational overhead by providing tools for deploying and managing cloud infrastructure, supporting phased migrations while maintaining existing systems, and adapting to evolving organizational needs and cloud advancements.
