AWS Lambda: Serverless Computing

AWS Cloud Practitioner to Architect: 0 to Hero

AWS Lambda

Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume.

How it Works:

  1. Event Driven: Triggered by changes in data (S3 upload), system state, or user action (API Gateway).
  2. Short Execution: Max execution time is 15 minutes.
  3. Automatic Scaling: Scales automatically by running copies of the function.

Supported Languages:

Python, Node.js, Java, Go, C#, Ruby.
