Before recommending any migration or new architecture, we run a fixed cost-audit checklist. It usually surfaces savings within the first day.
1. Orphaned resources
Unattached volumes, idle load balancers, and forgotten staging environments.
2. Oversized instances
Right-sizing against actual CPU/memory utilisation, not provisioned capacity.
3. Storage tiering
Cold data sitting in expensive hot storage tiers.
4. Reserved vs. on-demand mix
Predictable workloads paying on-demand rates unnecessarily.
5. Data transfer costs
Cross-region and egress charges that a re-architected data flow could avoid.
