CDN Edge Cache Hit Ratio Savings Calculator.

DevOps simulation showcasing cloud egress fee savings and origin server CPU reduction by offloading request traffic to an Edge CDN like Cloudflare or Fastly.

## The AWS Egress Trap

Cloud providers like AWS, GCP, and Azure charge exorbitant fees for data leaving their network to the internet (typically $0.09/GB). By placing a Content Delivery Network (CDN) in front of your cloud architecture and caching aggressively, you intercept the request at the edge.

### FAQ

**Q: What is a Cache Hit Ratio (CHR)?**
A: If your CHR is 85%, it means 85 out of 100 incoming requests were answered directly by the CDN's cache. Only 15 requests made it to your actual server. You only pay compute resources and egress fees on those 15 requests.
