Migrating to the Cloud: A Strategic Roadmap
David Miller
TechOS Consultant
A step-by-step guide for CIOs planning a large-scale cloud migration, covering assessment, planning, execution, and optimization.
Cloud migration is a complex undertaking that involves more than just "lifting and shifting" servers. It requires a fundamental rethink of how applications are architected and delivered.
Phase 1: Assessment
Before moving a single byte, you must understand your current estate. Use automated discovery tools to map dependencies between applications. Identify which apps are cloud-ready, which need refactoring, and which should be retired.
Phase 2: The 6 Rs of Migration
Amazon Web Services (AWS) famously defined the 6 Rs: Rehosting, Replatforming, Repurchasing, Refactoring, Retiring, and Retaining. Choosing the right strategy for each workload is critical for cost control and performance.
Post-migration, the focus shifts to optimization. Cloud native services offer auto-scaling and serverless computing options that can significantly reduce operational costs if managed correctly.
