Lamba – AWS’s serverless compute service.

AWS Lambda is a serverless compute service that runs code in response to events without requiring server management. It supports multiple programming languages (Python, Node.js, Java, Go, etc.) and automatically scales based on incoming request volume. Lambda functions can run for up to 15 minutes and are billed in 1ms increments of execution time. The service integrates deeply with other AWS services, allowing functions to be triggered by events from S3, DynamoDB, API Gateway, and more. Lambda provides built-in monitoring through CloudWatch, supports environment variables for configuration, and can be deployed within VPCs for accessing private resources. It includes features like provisioned concurrency for consistent performance and custom runtime support for additional languages.
