Doris Billing Examples

Billing Scenario

A user purchased a pay-per-use Doris cluster on March 18, 2023, 15:00:00 and planned to use it for one hour. After 0.5 hour, the user changed the specifications of the FE node from 8 vCPUs and 16 GB memory to 8 vCPUs and 32 GB memory. The user changed the cluster to a yearly/monthly one on March 18, 2023, 15:59:59 for a long-term use. The validity period was one month, and the cluster expired at 23:59:59 on April 18, 2023. This section shows how to calculate the total fee for using this cluster. Suppose the cluster specifications are as follows:

FE node specifications
- Compute: 8U16G
- Storage: High I/O and 300 GB/Node
- Nodes: 5
BE node specifications
- Compute: 8U16G
- Storage: High I/O and 400 GB/Node
- Nodes: 3

Billing Analysis

After a period of time, the user found that the current specifications cannot meet service requirements and expanded the cluster capacity on March 18, 2023, 15:30:00. The expanded specifications are as follows:

**Table 1** Billing change details
Billing Mode	Formula	Billing Cycle	Price
Pay-per-use billing (before specification change)	Compute unit fee: Unit price of a compute unit x Number of nodes	Hourly fee	FE nodes: $0.4256 USD/hour (Unit price of a compute unit) × 5 (Node quantity) × 1 hour = $2.128 USD BE nodes: $0.4256 USD/hour (Unit price of a compute unit) x 3 (Node quantity) x 1 hour = $1.2768 USD
	Disk fee: Disk unit price x Capacity x Number of nodes		FE nodes: $0.0001 USD/hour (Unit price) x 300 GB (Disk capacity) x 5 (Node quantity) x 0.5 hour (Usage duration) = $0.075 USD BE nodes: $0.0001 USD/hour (Unit price) x 400 GB (Disk capacity) x 3 (Node quantity) x 0.5 hour (Usage duration) = $0.06 USD
	Disk fee: Disk unit price x Capacity x Number of nodes		Total Price: $3.5398 USD
Pay-per-use billing (after specification change)	Compute unit fee: Unit price of a compute unit x Number of nodes	Hourly fee	FE nodes: $0.532 USD/hour (Unit price of a compute unit) x 5 (Node quantity) x 1 hour = $2.66 USD BE nodes: $0.4256 USD/hour (Unit price of a compute unit) x 3 (Node quantity) x 1 hour = $1.2768 USD
	Disk fee: Disk unit price x Capacity x Number of nodes		FE nodes: $0.0001 USD/hour (Unit price) x 300 GB (Disk capacity) x 5 (Node quantity) x 1 hour (Usage duration) = $0.15 USD BE nodes: $0.0001 USD/hour (Unit price) x 400 GB (Disk capacity) x 3 (Node quantity) x 1 hour (Usage duration) = $0.12 USD
	Disk fee: Disk unit price x Capacity x Number of nodes		Total Price: $4.2068 USD
Yearly/Monthly billing	Compute unit fee: Unit price of a compute unit x Number of nodes	Monthly fee	FE nodes: $255.36 USD/month (Unit price of a compute unit) x 5 (Node quantity) = $1276.80 USD BE nodes: $204.24 USD/month (Unit price of a compute unit) x 3 (Node quantity) = $612.72 USD
	Disk fee: Disk unit price x Capacity x Number of nodes		FE nodes: 0.04 USD/month (Unit price) x 300 (Disk capacity: GB) x 5 (Node quantity) = $60 USD BE nodes: 0.04 USD/month (Unit price) x 400 (Disk capacity: GB) x 3 (Node quantity) = $48 USD
	Total		Total Price: $1997.52 USD

From March to April, the total fee of the Doris cluster is 4.2068+1997.52=2001.7268 USD.

Doris clusters are billed by hour. The smallest billing unit for compute unit usage is one hour, and partial hours are counted as full hours.
How to bill a pay-per-use cluster whose billing mode is changed in the example above:
- Disk billing: For the initial half an hour, billing is based on the original specifications. After the change, billing of the entire period is based on the new specifications.
- CU billing: Similarly, for the initial half an hour, billing is based on the original specifications. After the change, billing of the entire period is based on the new configurations.
Periodic settlement of pay-per-use products:
- Settlement by hour: Huawei Cloud calculates the fee based on your usage every hour and deducts the fee from your account. For example, fees incurred from 8:00 to 9:00 are usually deducted before 10:00.
- Settlement by month: Huawei Cloud calculates the fee based on your usage and deducts the fee of the month at the beginning of the next month. For example, fees incurred from 00:00:00 on April 1, 2019 to 23:59:59 on April 30, 2019 are usually deducted at about 01:00:00 on May 1, 2019.
