Billing

Billing overview

This article describes billing details related to Function as a Service (veFaaS), including billing types, billing items, overdue payments, and unsubscription, and other billing information.

Billing type

Billing type	Description
Pay-as-you-go	(Default billing type) A postpaid billing method. You do not need to purchase massive resources in advance, and you can activate and release resources on demand anytime. You only need to pay for the veFaaS resources actually used.
Package	(Optional billing type) A package is a discount package launched for different billing items by the Function as a Service. This is a prepaid billing method. Currently the package provides function call packages, vCPU packages, and GPU packages, which are used respectively to deduct the corresponding billing items. After you purchase packages, you can enjoy an equivalent amount of resources with more preferential prices, and thus you can reduce your expenses.

tip

Volcano Engine also provides a Price calculator, through which you can configure the specifications of the billing items to estimate the fees in business scenarios. The price calculator only offers reference prices. For detailed payments, refer to the result of the actual orders of the Function as a Service (veFaaS) console.
