Fun is a developer tool for Serverless applications on Alibaba Cloud. It lets you define, develop, test, and debug Serverless applications locally before you publish them to the cloud. This topic describes how to use Fun to develop and debug Serverless applications on IoT Edge.
Serverless applications include Function Compute and related resources, such as events and API gateways. You can use the Alibaba Cloud Serverless Application Model (SAM) to define your Serverless applications.
You can use Fun to create a SAM project. You can then build, test, and debug the Serverless application defined by SAM in a local environment that simulates IoT Edge. This helps you identify issues before you publish the application. After development and testing, you can also use Fun to deploy the application directly to the cloud.
