The cloud is rarely more expensive than owning hardware, but the bill is more honest: you see immediately what waste costs. In almost every cost review we run, fifteen to thirty percent of spend turns out to be something nobody misses once removed.
Oversized machines
During a migration the old server capacity is often copied one-to-one, including the headroom once intended to cover five years of growth. In the cloud you pay for that headroom every month. Look at actual usage over three months and scale down.
Test environments that never switch off
An acceptance environment is typically used eight hours a day on weekdays, roughly a quarter of the week. Shutting it down automatically outside office hours immediately removes most of that cost.
Storage nobody touches
Snapshots of deleted machines, log files from years ago, backups of backups. Set retention periods and move old data to cheaper storage tiers. This is almost always the quickest saving.
No reservations for stable workloads
For systems that run all year anyway, reservations cut the price by up to forty percent. The reason organisations skip this is almost never substantive — it is simply not on anyone's list.
Cross-region data transfer
Traffic within one zone is usually free; traffic between regions is not. A database in one region with the application in another can produce a surprisingly large line item that no design ever deliberately chose.
Nobody who owns the bill
The deepest cause is organisational. As long as the cloud bill sits on one central cost centre, no team feels the consequences of a choice. Tags per team or project and a monthly overview per owner do more than any technical measure.
- In month one, set up a cost overview per team or project
- Clean up unused resources and old snapshots
- Automatically shut down non-production environments outside office hours
- Reserve capacity only after rightsizing, never before
