When you use Elastic High Performance Computing (E-HPC), you are charged for using resources of other cloud services. You may also need to pay additional fees for excess cores of your clusters. This topic describes the billable items and billing methods of E-HPC.
Additional fees
E-HPC allows you to manage clusters by using multiple methods. You can create or delete elastic nodes, call API operations, monitor cluster metrics, configure alerts, use O&M tools, and configure automated O&M for the backend. If your clusters in a region contain more than 1,000 cores in total, you are charged for the excess cores.
Billing
Region | Chinese mainland | Outside the Chinese mainland |
Billing rule | If the number of cores exceeds 1,000, you are charged for the excess cores. Unit price: USD 0.003/core/hour. | If the number of cores exceeds 1,000, you are charged for the excess cores. Unit price: USD 0.004/core/hour. |
Formula | (Total number of cores - 1000) × 0.003 × Usage duration | (Total number of cores - 1000) × 0.004 × Usage duration |
Billing method | Pay-as-you-go | |
Billing cycle | You are billed based on the number of clusters per second. You can calculate the price per second based on the following formula: Hourly price/3600. | |
Settlement cycle | Bills are updated on an hourly basis. | |
Billing examples
The following table provides several billing examples of additional fees in typical scenarios.
The prices that are described in the following examples are provided only for reference. The actual prices on the E-HPC bills take precedence.
Scenario | Billing | Hourly bill (USD) |
Create one cluster that contains 1,000 cores in the Singapore (Singapore) region. | You are not charged fees because the total number of cores does not exceed 1,000. | 0 |
Create two clusters in the China (Qingdao) region. One cluster contains 2,000 cores and the other contains 500 cores. | You are charged for the excess 1,500 cores based on the pay-as-you-go billing method. | (2500 - 1000) × 0.003 = 4.5 |
Create two clusters in the Singapore (Singapore) region. One cluster contains 2,000 cores and the other contains 500 cores. | You are charged for the excess 1,500 cores based on the pay-as-you-go billing method. | (2500 - 1000) × 0.004 = 6 |
Create one cluster in the China (Qingdao) region and another in the Singapore (Singapore) region. The cluster in the China (Qingdao) region contains 2,000 cores and the cluster in the Singapore (Singapore) region contains 200 cores. |
| (2000 - 1000) × 0.003 = 3 |
Resources of other cloud services
You are charged for using resources of other cloud services, such as Elastic Compute Service (ECS), Apsara File Storage NAS, and Elastic IP Address (EIP).
Cloud service | Billing | Pricing | References |
ECS | E-HPC clusters use ECS instances as nodes. When you create a cluster, an ECS instance that meets your requirements is automatically purchased for the cluster. | ||
NAS | E-HPC clusters use NAS file systems as the shared storage of the nodes in a cluster. Before you create a cluster, you must purchase a NAS file system. | ||
EIP | Elastic IP addresses are used for access over the Internet. If you create a cluster and deploy the cluster in Standard mode, an EIP is bound to the logon node of the cluster. If you create a cluster and deploy the cluster in Tiny mode, an EIP is bound to the management node of the cluster. You are billed for the EIP based on the traffic that is generated and the EIP uses a bandwidth of 100 Mbit/s. |
