Serverless Cloud Function (SCF)

Serverless Cloud Function (SCF) is Tencent Cloud's event-driven serverless compute service. SCF lets you run code without managing servers — the equivalent of AWS Lambda or Alibaba Cloud Function Compute.

What is SCF?

SCF allows you to:

• Write functions in supported languages
• Deploy without provisioning or managing servers
• Pay only for the compute time your code consumes
• Scale automatically from zero to thousands of concurrent executions

How SCF Works

1. You write a function and define a trigger
2. When an event occurs, SCF provisions the runtime
3. Your code executes and returns a result
4. After execution, the runtime may be reused or released

Event (e.g., COS upload, API Gateway request)
