How accurate is cloud simulation? We load-tested it and published the misses too. AWS: 93.8% on /accuracy. GCP, one topology in us-central1 at 300–500 RPS: 5 of 6 P95 holdout runs within 20%, 1 within 35%, all 6 P50 within 20%. Measured P95 was slower than predicted at every rung.

Egress quietly becomes one of the biggest lines on a small cloud bill. In our September 2026 pricing snapshot, tripling traffic (100→300 RPS) raised one small web stack's modeled cost ~48% on AWS, ~54% on GCP and ~12% on DigitalOcean, all from egress. 5 ways to cut it, with dated list prices:

What happens to your AWS stack if traffic triples? We pointed an MCP client at Cloud World Model, simulated ALB + 2× m5.large + db.r5.large MySQL, and went from 200 to 600 RPS: p99 87 → 422 ms errors 0 → 10%, all app CPU MySQL CPU flat at ~18% modeled cost $0.76 → $1.42/hr Real tool calls, honest limits:

The 33 cloud prices we track stayed flat in September. But tripling traffic from 100 to 300 RPS raised modeled costs: AWS: 48% GCP: 54% DigitalOcean: 12% Same fixed infrastructure. All modeled egress. Model the traffic before you deploy.
