FunctionGraph Best Practices

Updated on 2024-11-15 GMT+08:00

This document summarizes practices in common application scenarios of FunctionGraph. Each practice case is given detailed solution description and operation guidance, helping you easily build your services based on FunctionGraph.

Table 1 FunctionGraph best practices

Practice

Description

Processing DIS Data

When using the Data Ingestion Service (DIS) to collect real-time Internet of Things (IoT) data streams, process the collected data, for example, convert its format, and then store the processed data into the CloudTable Service (CloudTable).

Integrating with LTS to Analyze Logs in Real Time

Analyze and process key log data of servers such as ECS collected and converted by Log Tank Service (LTS), filter out alarm logs, store processed log data in a specified OBS bucket, and use SMN to push alarm messages to service personnel by SMS message or email.

Integrating with CTS to Analyze Login/Logout Security

Obtain operation records of subscribed cloud resources from Cloud Trace Service (CTS), analyze and process the records, report alarms, and use SMN to push alarm messages to service personnel by SMS message or email.

Periodically Starting or Stopping Huawei Cloud ECSs

Use FunctionGraph to call the corresponding ECS APIs to start or stop ECSs at specified time.

Building an HTTP Function with Spring Boot

Deploy services on FunctionGraph using Spring Boot.

Creating a FunctionGraph Backend API That Uses a Custom Authorizer

APIG supports IAM, app, and custom authentication. Create a FunctionGraph API that uses a custom authorizer.

Uploading Files with FunctionGraph and APIG

Uses Node.js and Python as examples to describe how to develop a backend parsing function for obtaining uploaded files, such as run logs and web application images, from devices to cloud servers based on FunctionGraph and APIG.

Processing IoT Data

Use FunctionGraph functions to process data reported by IoT devices and device status changes through IoTDA triggers.

Workflow + Function: Automatically Processing Data in OBS

Use a function flow to automatically process data in OBS, such as video analysis, image transcoding, and video frame capturing (available only in CN East-Shanghai1 and AP-Singapore).

Filtering Logs in Real Time by Using FunctionGraph and LTS

Obtain log data using an LTS trigger created on FunctionGraph, analyze and process key information in the logs by using a customized function, and then transfer the filtered logs to another log stream.

Building an HTTP Function with Go

Deploy services on FunctionGraph using Go.

Using FunctionGraph HTTP Functions to Process gRPC Requests

Process gRPC requests in FunctionGraph (only supported in LA-Santiago).

Cold Start Optimization Practices

Optimize FunctionGraph cold start.
