Treating cloud as just hosting: Avoid lifting-and-shifting monolithic apps without rethinking service boundaries—refactor important components before migrating.
Ignoring governance until scale: Establish minimal governance early (naming, tagging, security baseline) and evolve it—debt compounds fast in the cloud.
Vendor lock-in through proprietary APIs: Use abstraction layers and open formats; centralize provider-specific code so migration cost is minimized.
Over-optimizing for cost early: Focus first on reliability and observability; optimize costs after you can measure per-service usage accurately.
