Build your IoT Backend with AWS Lambda

AWS Lambda is a compute service that lets you run code without provisioning or managing servers. AWS Lambda executes your code only when needed and scales automatically, from a few requests per day to thousands per second.

The Internet of Things (IoT) Backend reference architecture (diagram) demonstrates how to use AWS Lambda in conjunction with Amazon Kinesis, Amazon DynamoDB, Amazon Simple Storage Service (Amazon S3), and Amazon CloudWatch to build a serverless system for ingesting and processing sensor data. By leveraging these services, you can build cost-efficient applications that can meet the massive scale required for processing the data generated by huge deployments of connected devices. Let's try it out!
