Data Egress Fees
Also known as: Egress Charges, Data Transfer Fees
Definition
Data egress fees are per-gigabyte charges for transferring data out of a cloud platform, whether to serve users, sync regions, or leave the provider. Alongside inter-zone transfer and managed-gateway charges, egress is one of the recurring line items practitioners name when a cloud bill surprises - and because it prices the exit itself, it functions as a switching cost that compounds with data growth.
Egress belongs in two models, not one: the monthly bill it inflates today, and the exit cost it adds to any future repatriation or vendor switch. Data-heavy architectures should price both before the data accumulates - it only gets more expensive to reconsider.
Related terms
- Cloud Repatriation — Moving workloads from public cloud back to owned, colocated, or hybrid infrastructure - what practitioners usually call 'leaving the cloud.'
- Switching Costs — The full cost of moving off a software vendor - migration, retraining, integration rework, and risk - which determines how much negotiating leverage you really have.
- Vendor Lock-In — The condition where leaving a software vendor is prohibitively expensive because of data, integrations, contract terms, or accumulated dependency.
