- Forgotten or idle resources are consistently the single biggest source of easy savings.

Forgotten resources are the easiest win
A staging environment left running at production scale after the project that needed it ended, an old database instance nobody decommissioned — these forgotten resources are consistently the single largest, easiest source of savings in a cloud cost audit, often uncovering a meaningful chunk of the total waste on their own.
Right-sizing rarely hurts performance
Instances provisioned generously 'to be safe' during initial setup are frequently running at a small fraction of their actual capacity months later. Right-sizing them down to match real usage, based on actual monitoring data rather than a guess, typically has no noticeable performance impact while meaningfully reducing cost.
Reserved pricing for predictable workloads
For infrastructure that runs consistently — not spiky, unpredictable traffic — committing to reserved or committed-use pricing instead of on-demand rates is a straightforward, low-risk way to cut costs on workloads that aren't going anywhere, in exchange for a modest commitment.
Auto-scaling instead of over-provisioning for peaks
Provisioning for worst-case peak traffic year-round, instead of scaling up automatically only when traffic actually demands it, means paying for peak capacity during the much larger share of time when traffic is normal. Proper auto-scaling captures the same peak handling without the constant overpayment.
Make cost review a recurring habit, not a one-time audit
Cloud waste tends to re-accumulate quietly after a one-time cost-cutting exercise, as new forgotten resources and over-provisioned instances build up again. A recurring quarterly review, even a lightweight one, prevents the savings from slowly eroding back to where they started.
