Billing

DDM allows you to pay only for what you use. There is no minimum fee.

Billing Items

You will be billed for DDM instances.

Table 1 DDM billing items

Billing Item

Description

DDM instance

Yearly/monthly and pay-per-use billing modes are available. The charges that you accrue for using DDM instances are based on compute nodes.

Public network traffic

DDM instances are accessible over both private and public networks. Only the traffic from public networks is billed.

For pricing details, see Product Pricing Details. You can use the price calculator to get a price estimate of a DDM instance with the node class you select.

Billing Modes

DDM provides the following two billing modes:

  • Yearly/Monthly: provides a larger discount than pay-per-use billing and is recommended for long-term use.
  • Pay-per-use (hourly): allows you to pay for only the resources you actually use. Pricing is listed on a per-hour basis, but bills are calculated based on the actual usage duration.

Configuration Changes

  • You can change the node class of your DDM instance based on service requirements. After the change, you are billed based on the new class.
  • You can add compute nodes to your DDM instance based on service requirements. After you add new compute nodes, you will be billed based on the new number of total compute nodes.
