This topic describes the billing of Simple Message Queue (SMQ, formerly MNS), including the billing method, billable items, billing cycle, and billing details.
Billing method
SMQ supports only the pay-as-you-go billing method. Fees are calculated each hour and bills are generated at an interval of 24 hours. Fees that are generated on the previous day are deducted from your Alibaba Cloud account balance based on the bill generated on the current day.
SMQ provides a price calculator:
Billable items
The following table describes the billable items of SMQ.
Fee for queues
You are charged based on the number of queues on a daily basis.
Billing formula
Fee for queues = Number of queues × Unit price of queues
Unit prices
Region | Unit price (USD per queue-day) |
China (Hangzhou), China (Shanghai), China (Shenzhen), China (Beijing), China (Qingdao), China (Zhangjiakou), China (Hohhot), China (Chengdu), China (Guangzhou), and China (Ulanqab) | 0.08 |
China (Hong Kong), Japan (Tokyo), South Korea (Seoul), Singapore, Thailand (Bangkok), Germany (Frankfurt), UK (London), US (Silicon Valley), US (Virginia), UAE (Dubai), Malaysia (Kuala Lumpur), and Indonesia (Jakarta) | 0.11 |
SAU (Riyadh) | 0.132 |
Queues are billed on a daily basis and the bills are issued to the Alibaba Cloud account.
If you no longer need a queue, delete the queue at the earliest opportunity to prevent unnecessary costs.
Billing examples
For example, you create queues in the China (Hangzhou) region. The following table describes the number of created queues and corresponding fees:
Date | Number of queues created | Number of queues billed | Unit price (USD per queue-day) | Fee (USD) |
Day 1 |
| 30 | 0.08 | 0.08 × 30=2.4 |
Day 2 | Created: 50 | 50 + 20 = 70 | 0.08 | 0.08 × 70=5.6 |
Fee for API requests to queues
Billing rules
The message body in each API request has a size limit of 64 KB. If you want to send a message whose size is larger than 64 KB, you must call multiple API requests to send the message. For example, if you want to publish or subscribe to a message of 256 KB, four API requests are called to publish or subscribe to the message. The number of API requests is calculated by using the following formula: 256/64 = 4.
You are charged for API requests to queues over the Internet and the internal network.
After you delete a queue, stop sending API requests to the queue at the earliest opportunity. Otherwise, you are still charged for the API requests that are sent to the queue.
Billing formula
Fee for API requests to queues = Total number of API requests to queues × Unit price of API requests to queues
Unit prices
SMQ provides a free quota of 20 million API requests per month. You are charged for the excess API requests. The following table describes the unit prices of API requests to queues:
Region | Unit price (USD per million requests) |
China (Hangzhou), China (Shanghai), China (Shenzhen), China (Beijing), China (Qingdao), China (Zhangjiakou), China (Hohhot), China (Chengdu), China (Guangzhou), and China (Ulanqab) | 0.32 |
Malaysia (Kuala Lumpur) and Indonesia (Jakarta) | 0.43 |
China (Hong Kong), Singapore (Singapore), Japan (Tokyo), Australia (Sydney), US (Silicon Valley), US (Virginia), Malaysia (Kuala Lumpur), Indonesia (Jakarta), and Germany (Frankfurt) | 0.46 |
SAU (Riyadh) | 0.552 |
Billing examples
For example, you create queues in the China (Hangzhou) region. The unit price for API requests to the queues is USD 0.32 per million requests. You are provided with a free quota of 20 million requests and charged for the excess requests. In this example, 22 million requests are sent to the queues, which exceeds the free quota by 2 million. In this case, the fee for API requests to queues is calculated based on the following formula: 2 x 0.32 = 0.64 USD.
Fee for topics
You are charged based on the number of topics on a daily basis.
Billing formula
Fee for topics = Number of topics × Unit price of topics
Unit prices
Region | Unit price (USD per million requests) |
