If the billing method for network usage of an instance that uses a public IP address does not meet your business requirements, you can change the billing method.
Prerequisites
Before you change the billing method for network usage of a subscription instance
from pay-by-bandwidth to pay-by-traffic, make sure that your account has the configuration
downgrade privilege.
Note You can click Privileges & Quotas on the Overview page to go to the Privileges and Quotas page and check whether your account has the
configuration downgrade privilege.
Background information
The billing methods available for network usage are pay-by-bandwidth and pay-by-traffic.
You can change the billing method based on your needs.
- Pay-by-bandwidth: You are charged based on the specified bandwidth. The actual outbound bandwidth does not exceed the specified bandwidth.
- Pay-by-traffic: You are charged based on the traffic that you actually used. You can
configure a peak bandwidth value for outbound traffic to avoid excess costs caused
by bursts in outbound traffic.
Notice When the pay-by-traffic billing method is used, the peak inbound and outbound bandwidth values are used as traffic limits instead of guaranteed performance. In scenarios where demands exceed resource supplies, the peak bandwidth values may be limited. If you need guaranteed bandwidth performance, select the pay-by-bandwidth billing method.
