Purchasing a Pay-per-Use CFW

Pay-per-use billing is a postpaid billing mode. A pay-per-use CFW can be provisioned and deleted at any time. CFWs are billed by second. The system generates a bill every hour based on the protected traffic and deducts the billed amount from the account balance.

You can purchase multiple firewalls in a region and assign them different resources and policies.

Prerequisites

The current account has the BSS Administrator and CFW FullAccess permissions.

Constraints

  • CFW can be used in the selected region only. To use CFW in another region, switch to the corresponding region and then purchase it. For details about the regions where CFW can be purchased, see Function Overview.
  • A maximum of 1 Gbit/s bandwidth traffic (total traffic passing through the firewall) can be protected.
  • Only the professional edition supports the pay-per-use billing mode.
