This topic describes the pricing of computing resource plans and how to purchase and view computing resource plans of ApsaraDB for ClickHouse clusters that run Enterprise Edition.
Limits
Computing resource plans are used to offset computing resource fees of ApsaraDB for ClickHouse clusters that run Enterprise Edition.
Computing resource plans are supported in the following regions: China (Hangzhou), China (Shanghai), China (Beijing), China (Shenzhen), China (Hong Kong), Japan (Tokyo), Singapore, Germany (Frankfurt), and US (Virginia).
Usage notes
The billing method of computing resource plans is subscription and is valid for three years.
NoteAfter you purchase a computing resource plan, the resource plan automatically offsets the fees of eligible computing resources.
After a computing resource plan is used up, the billing method of the computing resources of the cluster switches to pay-as-you-go.
A computing resource plan has a minimum capacity of 3,000 ClickHouse Compute Units (CCUs).
Computing resource plans do not support renewal. You can purchase additional computing resource plans. No limits are imposed on the number of computing resource plans you can purchase, and multiple resources plans can be used together.
Computing resource plans cannot be unsubscribed.
Pricing
The pricing provided in this topic is for reference only. The actual pricing in the console shall prevail.
A computing resource plan is priced at USD 0.03611 per CCU-hour, offering a discount of approximately 46.66% compared to the pay-as-you-go ApsaraDB for ClickHouse clusters that run Enterprise Edition in the Chinese mainland.
Offset rules
The pricing of computing resource plans is the same across all regions, including the regions in and outside the Chinese mainland and the China (Hong Kong) region. The offset factor varies by region. As a result, the fees for the amount of resources that can be offset also vary by region.
Offset formula
The required capacity of a computing resource plan to offset CCU usage is calculated based on the following formula: Required capacity = Actual CCU usage of a cluster × Offset factor of the region in which the cluster resides.
Offset factors in different regions
The offset factor is used to calculate the amount of resources whose fees a resource plan can offset in different regions.
In regions where the offset factor exceeds 1, more resource plan capacity is required than the actual resource usage. However, the total cost remains lower than the pay-as-you-go billing method. For more information, see Example 1.
Region | Offset factor |
China (Beijing), China (Hangzhou), China (Shanghai), and China (Shenzhen) | 1.00 |
China (Hong Kong) | 1.62 |
Singapore | 1.49 |
Japan (Tokyo) | 1.64 |
US (Virginia) | 1.16 |
Germany (Frankfurt) | 1.56 |
Offset examples
Example 1
The following example can help you understand how to use a resource plan to reduce costs.
You have an Enterprise Edition cluster that uses 10 CCUs for one hour in the Singapore region. The following items describe the billing details in different scenarios:
If you use the pay-as-you-go billing method, the fee is calculated based on the following formula:
USD 2.0595=10 CCUs × 1 hour×USD 0.20595 per CCU-hour.For more information, see Fees for Enterprise Edition.
If you use a resource plan, the required resource plan capacity is calculated based on the following formula:
14.9 CCUs per hour=10 CCUs × 1 hour×1.49. The resource plan fee is calculated based on the following formula:USD 0.538039=14.9 CCUs × 1 hour×USD 0.03611 per CCU-hour.
The preceding results show that although computing resources of 10 CCUs are used, you need a resource plan of 16.2 CCUs to offset the fees for the resource usage. However, compared with the pay-as-you-go billing method, the resource plan reduces costs by 73%, saving USD 1.521461. The value is calculated based on the following formula: USD 1.521461 = USD 2.0595 - USD 0.538039.
Example 2
The following example helps you understand how to use a resource plan.
You have the following resources within your Alibaba Cloud account:
A computing resource plan with a capacity of 360 CCUs per hour
An Enterprise Edition cluster in the Singapore region
An Enterprise Edition cluster in a region of the United States
An Enterprise Edition cluster in the China (HangZhou) region
The following table shows the computing resource usage of each cluster within an hour and the required capacity of the resource plan to offset the fees for the actual resource usage.
Cluster | Computing resource usage | Required capacity of the resource plan |
Enterprise Edition cluster in the Singapore region | 8 CCUs within 1 hour |
|
Enterprise Edition cluster in a region of the United States | 12 CCUs for the first 30 minutes and 8 CCUs for the next 30 minutes |
|
Enterprise Edition cluster in the China (HangZhou) region | 16 CCUs within 1 hour |
|
After an hour, the remaining capacity of the resource plan is calculated based on the following formula: 360 CCUs per hour - 11.92 CCUs per hour - 11.6 CCUs per hour - 16 CCUs per hour = 320.48 CCUs per hour.
Purchase a computing resource plan
Computing resource plans do not support refunds. We recommend that you estimate your resource usage before you purchase a computing resource plan to avoid waste. If the resource usage exceeds the capacity of a computing resource plan, you are charged for the excess resource usage based on the pay-as-you-go billing method.
