How cloud bills quietly triple
Nobody decides to overspend on cloud. It accumulates: instances sized for a launch spike that never came down, staging environments running around the clock, storage nobody audits, and data transfer costs invisible until the invoice arrives.
The 30-40% that is almost always there
In our cloud migration and optimisation work, the same wins repeat: right-sizing compute against actual utilisation, moving predictable workloads onto reserved or spot capacity, tiering cold storage, and deleting zombie resources — snapshots, orphaned volumes, forgotten load balancers.
One recent migration cut infrastructure costs 40% while eliminating downtime deployments entirely. The savings were not exotic — they were disciplined application of these basics, codified in Terraform so the environment cannot drift back.
Make cost a first-class metric
Sustainable savings come from visibility: cost dashboards per team and per service, budgets with alerts, and cost review in the same meeting as performance review. What engineering can see, engineering will optimise.
