Egress
Noun · Development
Definitions
Data transferred out of a cloud provider's network to the internet or another region. Cloud providers typically charge for egress but not ingress, making it one of the most surprising line items on cloud bills. A major factor in vendor lock-in.
In plain English: Data leaving a cloud provider's network, which they charge you for — often the surprise on your cloud bill.
Example: "We're paying $8,000/month in egress fees alone — moving the CDN origin closer to the storage bucket would cut that in half."
