About EgressCost.com
An independent reference for cloud egress pricing. Operated by Digital Signet, founded by Oliver Wakefield-Smith. Sourced from each cloud provider's published egress pricing page so the figure can be verified before architecting around it.
Why this site exists
Egress pricing is one of the most opaque costs in cloud infrastructure: each provider's pricing page lists the rate but uses different units (per GB vs per TB), different tiering, different region multipliers, and different treatments for inter-region transfer. Comparing them across providers requires a consistent unit and a transparent calculation.
This site exists to publish the per-GB rate for each provider, surface the architectural gotchas (NAT Gateway surcharge, inter-region multipliers, hidden compute attribution), and provide a calculator that takes a monthly transfer volume and returns a like-for-like figure. There is no email gate. There is no chat widget.
Who runs the site
Oliver runs Digital Signet, an independent AI-development studio that builds data-led pricing and decision tools using public datasets. After 20 years as a solutions architect and tech lead across media, utilities, satellite, and data, he founded Digital Signet to apply autonomous AI development methodology to real software at scale.

About Digital Signet
This site is operated by Digital Signet, an independent AI-development studio founded by Oliver Wakefield-Smith. It is part of a portfolio of consumer cost-reference and calculator sites we run as a live R&D lab for our Signet methodology, an autonomous AI development team that ships real software at scale.
Digital Signet does not act as a cloud reseller, does not sell migration services, does not run a managed cloud practice, and does not accept paid placements from AWS, Azure, GCP, Cloudflare, Backblaze, Wasabi, or any other provider in the cloud-infrastructure space. Editorial direction is set by Oliver. Drafts are produced via Digital Signet's autonomous AI development methodology and reviewed against the editorial framework before publication.

Editorial principles
- Single primary source per provider. Each provider's egress rate comes from that provider's published pricing page (aws.amazon.com, azure.microsoft.com, cloud.google.com, cloudflare.com, etc.). The provider page is linked on every per-provider page; verify before architecting.
- Calculator math is documented inline. Inputs (monthly GB, region, inter-region split) and the per-provider math are visible on the calculator. Nothing is hidden.
- No paid placements. No supplier sponsorships. Independent of every cloud provider, reseller, and managed-cloud practice.
- Update only when published rates change. When a provider revises egress pricing, the relevant per-provider page is updated to match.
