The Vendor Egress Cost Watch

Sending telemetry to a vendor costs egress fees. The watch, the trade-offs of in-region collectors, and the surprises.

Cost model

Cloud provider egress: $0.05-0.12 per GB. Telemetry volume can be 1-10TB/month.

$50-1200/month per service can land in egress alone.

Reductions

In-region collectors that compress before egress. 5-10x reduction in egress bytes.

Sampling and filtering at the collector. Don't ship what you wouldn't query.

Watch

Per-service egress dashboard. Cost owner per service.

Surprises: a service that doubled its volume in a week. Tag the cause; act.
