Cloud Migration Strategy: AWS & GCP Guide

A successful cloud migration is a business project, not just a technical one. The goal is measurable outcomes — lower cost, higher reliability, faster delivery — not lifting servers for their own sake.

Choose the right migration pattern

The classic 6 R's — rehost, replatform, refactor, repurchase, retain, retire — help you decide per workload. Quick wins often come from rehosting, while long-term value comes from selectively refactoring.

Migrate with minimal downtime

Use database replication and a phased cutover so traffic shifts gradually. Blue-green deployments and feature flags let you roll back instantly if something misbehaves.

Control cost from day one

Tag resources, set budgets and alerts, right-size instances, and use committed-use discounts. FinOps discipline is the difference between cloud savings and cloud surprises.
