This topic describes how to deploy a Tornado application to Function Compute. Function Compute provides a method different from traditional deployment methods. You can deploy a traditional Tornado application to Function Compute and use the application for production without performing operations such as purchasing a server. The deployed Tornado application can use the auto scaling, pay-as-you-go, and O&M-free features of Function Compute.


The following operations are complete:


  1. Run the following command in the specified directory to initialize a project:
    s init devsapp/start-tornado -d start-tornado
    The -d parameter specifies the project name. In this example, the project name is start-tornado.
    Note Skip this step if the project already exists.
    Sample command output:

After the project is deployed, you can view the temporary domain name that is generated by Function Compute in the output. The temporary domain name can be used to access the newly deployed application. For example, run the following command to access the application:

curl http://tornado.serverless-devs-tornado.188077086902****
Note You can use the temporary domain name only for demonstration and development purposes. It is valid for a limited period of time. In a production environment, you must use a domain name for which an Internet Content Provider (ICP) filing is obtained from Alibaba Cloud. For more information, see Configure a custom domain name.
