The blog post discusses how to plan a cloud migration strategy while avoiding chaos. It emphasizes the importance of prioritizing which systems to migrate based on two key factors: architectural complexity and licensing constraints. Systems built on service architecture are generally easier to migrate than monolithic systems. The post also covers considerations for choosing the right cloud platform, including available capabilities, costs, team expertise, and developer preferences.

The article introduces AWS’s 6R migration strategies: Rehosting (lift and shift), Replatforming (migrating with some component upgrades), Repurchasing (replacing with SaaS solutions), Refactoring/Rearchitecting (rebuilding for cloud-native architecture), Retiring (decommissioning unnecessary systems), and Retaining (keeping systems as they are). The post recommends starting the migration with simpler systems to gain valuable learning experience before tackling more complex ones.
