AWS Lambda

Section : Serverless Computing

Run code without any servers.

Lambda as an event-driven computing platform, Lambda runs when triggered by an event and

executes code that’s been loaded into the system.

Use Case 1 :

Every time an image is uploaded into Amazon Simple Storage Service (S3), a Lambda function could automatically resize the image. The Seattle Times uses this to automatically resize images for mobile, tablet and desktop devices. The event that triggers the Lambda function is the file being uploaded to S3. Lambda then executes the function of resizing the image.

Use Case 2 :

Localytics processes billions of data points in real-time, and uses Lambda to process historical and live data stored in S3 or streamed from Kinesis
