Serverless billing

Example 1: Cost reduction

Purchasing a Serverless compute resource package reduces your costs.

Scenario
You have a Serverless application in the China (Zhangjiakou) region. This application consumes an average of 100 SCU of compute resources over one hour, for a total consumption of 100 SCU*H. The costs for this usage are calculated as follows:

• With pay-as-you-go, your cost is CNY 32.83 = 100 SCU*H × CNY 0.3283/SCU*H.

  (CNY 0.3283/SCU*H is the pay-as-you-go rate for the China (Zhangjiakou) region.)

• When using a resource package, the deduction is calculated as follows:

  1. Calculate the deduction amount: Because the deduction factor for this region is 0.700003, the amount deducted from your resource package is 70.0003 SCU*H = 100 SCU*H (actual usage) × 0.700003 (deduction factor).

  2. Calculate the deducted cost: The cost covered by the resource package is CNY 21.46 = 70.0003 SCU*H (deducted amount) × CNY 0.30663/SCU*H (resource package unit price).

Conclusion
Although your application consumed 100 SCU*H of resources, only about 70 SCU*H was deducted from your resource package. Using the resource package instead of pay-as-you-go saves you CNY 11.37 (CNY 32.83 - CNY 21.46), a cost saving of nearly 35%.

Example 2: Cross-region deductions

A shared Serverless compute resource package offsets consumption across multiple regions.

Scenario:
Your account has the following resources:

• A shared Serverless compute resource package with a capacity of 5,000 SCU*H.

• An application in the China (Zhangjiakou) region.

• An application in the China (Heyuan) region.

• An application in the China (Chengdu) region.

The following table shows the compute resource usage for each application over one hour and the corresponding deduction from the resource package.

Conclusion:
The total amount deducted from the resource package for the hour is the sum of the deductions from each application: 140.0006 (Zhangjiakou) + 202.5007 (Heyuan) + 90.0003 (Chengdu) = 432.5016 SCU*H.

The remaining capacity of the resource package is: 5,000 SCU*H - 432.5016 SCU*H = 4567.4984 SCU*H.

Example 1: Cost savings with a resource pack

Scenario
A Serverless application in the Germany (Frankfurt) region consumes 100 SCU*H of computing resources over one hour. The costs for this usage under different billing methods are as follows:

• With pay-as-you-go, your cost is $11.344 = 100 SCU*H × $0.113440/SCU*H.

  ($0.113440/SCU*H is the pay-as-you-go price for the Germany (Frankfurt) region.)

• Using a resource pack, the calculation is as follows:

  1. Calculate the deduction amount: With a deduction factor of 1.563 for this region, the amount deducted from your resource pack is 156.3 SCU*H = 100 SCU*H (actual usage) × 1.563 (deduction factor).

  2. Calculate the cost of the deduction: The cost of the deducted amount is $7.4253 = 156.3 SCU*H (deduction amount) × $0.04750625/SCU*H (resource pack unit price).

Conclusion
This analysis shows that while your application's actual usage is 100 SCU*H, the deduction factor results in a 156.3 SCU*H deduction from your resource pack. Despite this, the low unit price of the resource pack means you still save $3.9187 ($11.344 - $7.4253) compared to the pay-as-you-go method. This is a cost saving of nearly 34.5%.

Example 2: Cross-region deductions

A universal Serverless computing resource pack offsets consumption across multiple regions.

Scenario
Your account has the following resources:

• A universal Serverless computing resource pack with a capacity of 10,000 SCU*H.

• An instance in the Malaysia (Kuala Lumpur) region.

• An instance in the Germany (Frankfurt) region.

• An instance in the Philippines (Manila) region.

The following table shows each application's resource usage over one hour and the corresponding deduction from the resource pack.

Conclusion
The total deduction amount for the hour is the sum of the deductions for each application: 70.6 (Kuala Lumpur) + 125.04 (Frankfurt) + 120.42 (Manila) = 316.06 SCU*H.

The remaining capacity of the resource pack is: 10,000 SCU*H - 316.06 SCU*H = 9683.94 SCU*H.
