IoT Telemetry Ingestion on AWS Serverless

1. Introduction

In this lesson, we will explore how to implement IoT telemetry ingestion using AWS Serverless architecture. The Internet of Things (IoT) generates vast amounts of telemetry data, and leveraging AWS services allows for efficient data processing without managing infrastructure.

2. Key Concepts

3. Step-by-Step Process

Follow these steps to set up an IoT telemetry ingestion system using AWS Serverless:

1. Setup AWS IoT Core:

   Create an IoT thing and obtain the necessary certificates.

2. Create an AWS Lambda Function:

   Write a Lambda function to process incoming telemetry data.

   exports.handler = async (event) => {
       // Process incoming telemetry data
       console.log("Incoming telemetry data:", JSON.stringify(event));
       return { statusCode: 200, body: "Data processed" };
   };

3. Setup DynamoDB for Data Storage:

   Create a DynamoDB table to store telemetry data.

4. Configure IoT Rules:

   Create an IoT rule to trigger the Lambda function when telemetry data is received.

5. Test the Ingestion Pipeline:

   Send test telemetry data to the IoT endpoint and verify it is stored in DynamoDB.

4. Best Practices

• Use AWS IoT policies for fine-grained access control.
• Implement error handling and logging in your Lambda function.
• Monitor usage and performance using AWS CloudWatch.
