Cloud decisions: when to migrate and when to wait
Cloud is the right default for most new workloads, but existing systems deserve a case-by-case decision. A simple framework separates the clear wins from the expensive mistakes.
Default to cloud for new workloads
For anything new, the case is straightforward: no hardware to procure, capacity that scales with demand, and operations handled by the provider. The exceptions, such as hard latency requirements or strict data-residency constraints, are known and checkable.
The harder question is never the new system. It is what to do with the ten-year-old one that still runs the business.
A simple decision framework
Score each existing system on three questions: how much it will change in the next two years, how much its current hosting costs in total, including maintenance and risk, and how cleanly it can move. Systems that are changing, expensive, and portable should move. Systems that are stable, cheap, and brittle can often wait.
Rehosting a stable system rarely pays back; rebuilding a system the business depends on carries its own risk. The middle path, modernizing onto a platform as you adopt it, is where most successful migrations land.
Watch the total cost, not the invoice
Cloud costs surprise organizations that migrate without changing how they operate: oversized instances, unmanaged storage growth, and duplicated environments. FinOps practices, tagging, budgets, and regular reviews, keep spend aligned with value.
Measure migration success in business terms: time to deliver new capabilities, incident reduction, and the retirement of the legacy estate. Cost per transaction is a means, not the goal.
