Overview

CBH supports yearly/monthly and pay-per-use billing modes.

Yearly/Monthly billing is a prepaid mode in which you pay for the service before using it. Your bill is generated based on the required duration you specify in the order. The longer the subscription term, the bigger the discount. This mode is applicable to services that have long-term and stable requirements.

Pay-per-use billing is a postpaid mode in which you pay for what you use by the hour.

Table 1 lists billing modes supported by CBH.

Currently, the pay-per-use billing mode applies only to the government cloud zone.
