Also called: egress fee, egress fees, data transfer, data transfer out, bandwidth, bandwidth cost, outbound data

Data leaving a [cloud provider](https://ecosystem.samcarlton.com/cloud-provider)'s network, for example when a visitor downloads a file. Some providers charge for it, and that charge is often called an egress fee.

**For example:** A video startup stores its files with one provider. Each time a customer watches a video, data leaves that provider's network and adds to the bill.
