DEAWS Lambda explained with a real backend example.
When a user uploads an image to Amazon S3, it triggers an AWS Lambda function automatically. That function runs image processing logic and resizes the photo for web, mobile, and tablet — without managing any server.
This is serverless architecture in action.
No always-on backend.
No infrastructure management.
You pay only for execution time.
If you're learning cloud computing, backend development, or AWS architecture, understanding event-driven systems like S3 + Lambda is essential.
