AWS Lambda is Amazon's Function as a Service offering that runs code in response to events without provisioning servers. It automatically manages compute resources, scaling, and availability. How it works:
Deploy code: Upload function code in supported languages (Python, Node.js, Java, etc.)
Configure triggers: Set up event sources (API Gateway, S3, DynamoDB)
Execution: Lambda creates container instances when events trigger functions
Auto-scaling: Automatically scales concurrent executions based on demand
Billing: Pay for compute time in 1ms increments Lambda handles infrastructure management, security patching, monitoring, and logging, allowing developers to focus solely on application logic.
