Network Egress Cost Controls That Pay

Egress fees can be 30-50% of cloud bill. The four controls that cut egress materially.

In-region traffic

Place services that talk in the same region. Cross-region egress is 10x intra-region.

Verify with VPC flow logs. Surprises hide in legacy routing.

gzip on HTTP responses. Brotli where supported.

Compression at the application reduces bytes; egress drops proportionally.

Public-facing traffic via CDN. CDN egress is cheaper than direct cloud egress.

Caching helps too: served bytes count, but only on first miss.

Per-service egress dashboard. Sort by cost; investigate top contributors.

Most teams find one or two unexpected high-egress services.
