Overview
CloudBase SCF is a serverless computing service provided by cloud development, allowing you to run backend code without the need to manage servers.
SCF runs on a Serverless base. You just need to write code in supported languages (Python, Node.js, PHP, Golang, Java, etc.), and CloudBase will fully manage the underlying computing resources. CloudBase automatically handles the management and maintenance of the underlying infrastructure.
If you are a first-time user of SCF, it is recommended to read the Quick Start document to quickly experience the basic features of SCF.
Quick Start
How to write a cloud function - Learn how to write a cloud function
Scheduled trigger - Trigger SCF at scheduled times
Preset concurrency - Resident cloud function instance
Manage SCF via CLI - Quickly manage cloud functions through the command line
Layer management - Independently manage resources like dependency libraries and common code files to enable code reuse across multiple functions
SCF security rule - Precise control over user invocation permissions for cloud functions
What Is SCF
SCF is an event-driven computing service that allows you:
Focus on business logic: Just write core business code, no need to worry about server configuration, maintenance, and scaling.
Run as needed: Functions only run when called and incur no fees when no resources are consumed.
Automatic scaling: Automatically adjust computing resources based on request volume, scaling from zero to tens of millions in concurrency level.
Multiple trigger sources: Support SDK calls, HTTP requests, timers, and other trigger modes.
