GB / month

Service-to-service calls, load balancing and database replicas in other zones of the same region.

How is cloud data transfer billed?

monthly = tiered(internet egress) + CDN delivery + misses × origin fetch + inter-region GB × rate + cross-AZ GB × rate + NAT gateways × hourly × 730 + NAT GB × processing rate

This page uses the same method as the Cloud Egress Cost Calculator, which explains each term and assumption in full.

Worked example

A workload in North America: 10 TB a month to the internet, 500 GB to another region, 1,000 GB across zones, 500 GB through NAT, on 3 servers.

  1. 1Google Cloud: internet egress $1,137, inter-region $10.00, cross-az $10.00, nat gateway hours $3.07, nat data processed $22.50 = $1,182
  2. 2Microsoft Azure: internet egress $882, inter-region $10.00, nat gateway hours $32.85, nat data processed $22.50 = $948
  3. 3Difference: $235 a month

Microsoft Azure is $235 a month cheaper for this workload, $2,815 a year.

Frequently asked questions

Is Google Cloud or Microsoft Azure cheaper for egress?

For internet egress from North America on 3 servers at list rates, at 1 TB a month Microsoft Azure costs $80.39 against $123; at 10 TB a month Microsoft Azure costs $882 against $1,137; and at 100 TB a month Microsoft Azure costs $7,868 against $8,509. Zone, NAT and CDN charges can change the answer, so enter your own traffic.

Is Google Cloud or Azure cheaper for CDN delivery?

At small volumes, Cloud CDN: it starts at $0.08 per GB with no base fee, while Azure Front Door Standard adds $35 a month before its $0.0825 per GB. At large volumes Front Door pulls ahead, falling to about $0.014 per GB past 150 TB where Cloud CDN charges $0.03. Google also bills cache fill on misses, $0.01 per GB in North America and Europe.
