Most AWS bills hide 30% of avoidable spend. The levers are well known — the discipline to pull them continuously is what is scarce.
The usual suspects
Idle and oversized resources top the list: instances running at 5% utilisation, forgotten test environments, unattached storage volumes and outdated snapshots. Right-sizing and scheduling non-production environments alone typically save 20–30%.
Commit where usage is steady
Savings Plans and Reserved Instances reward predictable baseline usage with discounts up to 70%. The key is analysing actual usage first — committing to capacity you do not use converts waste into a contract.
Make cost a team sport
Sustainable optimisation needs visibility: cost allocation tags, budgets with alerts, and regular reviews where engineering teams see the cost of their own services. FinOps is a practice, not a one-time project — Zrosis Technologies helps clients embed it into their cloud operating model.
