Process events with serverless code


Azure Functions provide a serverless development experience supporting a robust set of event triggers and data bindings.

Azure Functions pricing

Azure Functions consumption plan is billed based on per-second resource consumption and executions. Consumption plan pricing includes a monthly free grant of 1 million requests and 400,000 GB-s of resource consumption per month per subscription in pricing across all function apps in that subscription. Customers can also run Functions within their App Service plan at regular App Service plan rates.

*The following prices are tax-inclusive.

*Monthly price estimation is based on a usage of 31 days per month.
Execution Time* ¥ 0.000113/GB-s 400,000 GB-s
Total Executions* ¥ 1.30 per million executions 1 million executions
* Free grants apply to paid, consumption subscriptions only.

Note - A storage account is created by default with each Functions app. The storage account is not included in the free grant. Standardstorage ratesandnetworking rates charged separately as applicable.

Pricing details


Functions are billed based on total number of requested executions each month for all functions. Executions are counted each time a function is executed in response to an event, triggered by a binding. The first million executions are included free each month.

Resource consumption

Functions are billed based on observed resource consumption measured in gigabyte seconds (GB-s). Observed resource consumption is calculated by multiplying average memory size in gigabytes by the time in milliseconds it takes to execute the function. Memory used by a function is measured by rounding up to the nearest 128 MB, up to the maximum memory size of 1,536 MB, with execution time calculated by rounding up to the nearest 1 ms. The minimum execution time and memory for a single function execution is 100 ms and 128 mb respectively. Functions pricing includes a monthly free grant of 400,000 GB-s.

Premium plan

Azure Functions Premium plan provides the same features and scaling mechanism used on the Consumption plan (based on number of events) with no cold start, enhanced performance and VNET access. Azure Functions Premium plan is billed based on the vCPU and memory that your functions consume.

vCPU duration vCPU: ¥1.626 vCPU/hour
Memory duration Memory: ¥0.1158 GB/hour
*Azure Premium Functions plan generally availability pricing will be effective for China North 2 and China East 2 on January 1, 2021

Functions Proxies

The same pricing applies to Functions Proxies. A proxy is a function that is triggered by an HTTP request. Memory used by a proxy is less than 128 MB. Proxy execution time is the round-trip time (request to response), because the proxy needs to stay up to keep the HTTP connection alive. If a proxy triggers a function, the function execution and memory usage is counted separately.

Pricing example

A function with observed memory consumption of 512 MB executes 3,000,000 times during the month and has an execution duration of one second. Monthly billing would be calculated as follows:
