Why Cloud Bills Creep Up (And How to Fix It)
Most cloud-native companies overpay by 30% to 50% on AWS or Azure bills. The root cause is almost always **over-provisioned container requests** and unmanaged idle resources.
4 Quick FinOps Wins
- **Set Realistic CPU/Memory Requests:** If your container uses 300MB RAM at peak, requesting 2GB reserves unallocatable memory that you still pay for.
- **Karpenter / Autoscaling Spot Instances:** Run non-critical batch jobs, workers, and dev environments on spot instances at 70% discount.
- **Egress Optimization:** Keep inter-service communication inside the same Availability Zone where possible, or use VPC peering endpoints.
- **S3 Lifecycle Rules:** Automatically move logs and backups older than 30 days to S3 Glacier Flexible Retrieval or Deep Archive.
