Overview

CCM provides two billing modes: one-time billing and pay-per-use billing for you to meet your needs.

• One-time billing applies only to SSL certificates. When purchasing an SSL certificate, a one-time fee is charged based on the certificate type, certificate authority, domain type, number of domain names, and required duration you select.
• Pay-per-use billing is a postpaid mode in which you pay for what you use. This mode applies only to private CAs and certificates. Private CAs and certificates are billed by the second and settled by the hour. With the pay-per-use billing mode, you can easily adapt to resource requirement changes, reducing the risk of over-provisioning of resources or lacking capacity. In this mode, there are no upfront commitments required.

  Table 1 describes the differences between the billing modes.
