Egress was the whole cost increase. How do you keep it down?

Following up on the September thread: when we tripled traffic on that small stack (load balancer, two app servers, MySQL), modeled cost went up about 48% on AWS, 54% on GCP and 12% on DigitalOcean. All of the increase came from egress, meaning data leaving the provider's network.

So we wrote up how each provider bills it, with list prices retrieved Nov 3–4, 2026:

• AWS charges $0.09/GB after 100 GB a month.

• GCP Premium Tier charges $0.12/GiB after the first 1 GiB.

• DigitalOcean pools a transfer allowance across your Droplets, then charges $0.01/GiB.

The post also covers five ways to cut egress: cross-zone traffic, CDN and caching, smaller responses, NAT gateway charges, and plan allowances.

What's actually moved your egress bill: a CDN, compression, re-architecting cross-zone traffic, or something else?
