A practical guide to cloud migration for modern companies

Cloud migration earns its scary reputation from big-bang cutovers — the kind where everything moves at once and there's no way back. There's a better way.

Migrate in reversible stages

We break migrations into small, reversible steps. Each step delivers value on its own and can be rolled back independently, so you're never one deploy away from an outage.

• Assess: inventory workloads, dependencies and data gravity.
• Containerise: package services so they run identically anywhere.
• Automate: infrastructure as code and CI/CD before you move traffic.
• Cut over: shift traffic gradually with observability watching every metric.

The payoff

Done well, migration lowers cost, increases deploy frequency and improves reliability — all while the business keeps running. One recent client cut cloud spend 45% and increased deploy frequency 10x with zero downtime.
