Before you use Function Compute service, you must have signed up for Alibaba Cloud. After you sign up for Alibaba Cloud, your account is automatically signed up for Function Compute service.
For each request, the service endpoint and the user account ID must be contained in a formatted pattern: account_id.service_endpoint. For example, assuming that your account ID is 16530750, then you can access Function Compute resources that are in China East 2 (Shanghai) region by using the 16530750.cn-shanghai.fc.aliyuncs.com address.
Internet service endpoint
Function Compute is accessible with the following public endpoints. You are billed for internet usage if your function is transmitting data in and out from the Alibaba Cloud infrastructures from the internet. For more information, see Billing method.
See the following table for the Internet service endpoints.
| Region | Service endpoint |
|---|---|
| China East 1 (Hangzhou) | cn-hangzhou.fc.aliyuncs.com |
| China East 2 (Shanghai) | cn-shanghai.fc.aliyuncs.com |

| China South 1 (Shenzhen) | cn-shenzhen.fc.aliyuncs.com |
| Hong Kong | cn-hongkong.fc.aliyuncs.com |
| Asia Pacific NE 1 (Tokyo) | ap-northeast-1.fc.aliyuncs. com |
| Asia Pacific SE 1 (Singapore) | ap-southeast-1.fc.aliyuncs.com |
| Asia Pacific SE 2 (Sydney) | ap-southeast-2.fc.aliyuncs.com |
Intranet service endpoint
Some Alibaba Cloud services can communicate over intranet, such as Function Compute, ECS, Apsara for RDS, Server Load Balancer, and OSS. We have established a gigabit level of shared bandwidth for those services that are in the same region. If you are transmitting data among Alibaba Cloud services that are in the same region, we recommend you use an intranet connection to avoid the consumption of Internet traffic.
See the following table for the intranet service endpoints.
| Region | Service endpoint |
|---|---|
| China East 1 (Hangzhou) | cn-hangzhou-internal.fc.aliyuncs.com |
| China East 2 (Shanghai) | cn-shanghai-internal.fc.aliyuncs.com |
| China North 2 (Beijing) | cn-beijing-internal.fc.aliyuncs.com |
| China South 1 (Shenzhen) | cn-shenzhen-internal.fc.aliyuncs.com |
| Hong Kong | cn-hongkong-internal.fc.aliyuncs.com |
| Asia Pacific NE 1 (Tokyo) | ap-northeast-1-internal.fc.aliyuncs. com |
| Asia Pacific SE 1 (Singapore) | ap-southeast-1-internal.fc.aliyuncs.com |
| Asia Pacific SE 2 (Sydney) | ap-southeast-2-internal.fc.aliyuncs.com |
