Cloud waste rarely comes from one big mistake. It accumulates quietly: an oversized instance here, an orphaned volume there, a dev environment that runs weekends. Across our FinOps engagements, savings of 30–50% are the norm, and they come from the same five places.
1. Right-sizing
Most workloads are provisioned for peak-day traffic and run at 15% utilization the rest of the time. Autoscaling groups, burstable instances, and honest load testing fix this.
2. Orphaned resources
Unattached disks, idle load balancers, forgotten snapshots, and zombie dev environments. Tag everything, then automate cleanup of anything untagged.
3. Storage tiers
Data that hasn't been read in a year doesn't belong on premium SSD. Lifecycle policies that move cold data to archive tiers routinely cut storage bills in half.
4. Commitment discounts
If your baseline load is predictable, reserved instances and savings plans are free money — 30–60% off list price for a commitment you were going to make anyway.
5. Data transfer
The sneakiest line item. Cross-zone chatter, unnecessary egress, and un-cached assets add up. An architecture review focused purely on data flow often finds five figures a year.
The best part: none of these reduce capability. It's the same system, engineered properly.
