How Do I Use FunctionGraph?

Process

1. Write code, package and upload it to FunctionGraph, and add event sources such as Simple Message Notification (SMN), Object Storage Service (OBS), and API Gateway (APIG) to build applications.
2. Functions are triggered by RESTful API calls or event sources to achieve expected service purposes. During this process, FunctionGraph automatically schedules resources.
3. View logs and metrics.

1. Write code in Node.js, Python, Java, Go, C#, or PHP. For details, see the FunctionGraph Developer Guide.
2. Edit code inline, upload a local ZIP or JAR file, or upload a ZIP file from OBS. For details, see Table 3.
3. Functions are triggered by API calls or event sources. For details, see Using an SMN Trigger, Using an APIG (Dedicated) Trigger, Using an OBS Trigger, Using a DIS Trigger, Using a Timer Trigger, Using a CTS Trigger, Using an LTS Trigger, and Using a Kafka Trigger.
4. FunctionGraph implements auto scaling based on the number of requests. For details about the maximum number of function instances that can be run concurrently, see Quotas and Usage Restrictions.
5. View run logs of function as FunctionGraph is interconnected with Log Tank Service (LTS). For details, see Querying Logs.
6. View graphical monitoring information as FunctionGraph is interconnected with Cloud Eye. For details, see Viewing Function Metrics.
