AWS Lambda Lambda Function Icon

AWS Lambda lets you run code without managing servers. You upload your code, and Lambda takes care of everything required to run it, scaling automatically based on demand. It's perfect for handling events like processing data from an S3 bucket, reacting to changes in a DynamoDB table, or responding to HTTP requests from API Gateway. You only pay for the compute time your code actually consumes, making it very cost-effective for event-driven applications.
