AWS Lambda


Serverless Cloud Compute - AWS Lambda

AWS Lambda a serverless compute service.

This service lets you run code without needing to think about servers.

It lets you focus on what's most important, such as making a great application.

You only pay for the compute time that you use.

Pay for what you use translates to that you only pay when your code is running.

How AWS Lambda Works

The high-level steps to understand the concept:

  1. Deploy your code to Lambda
  2. Make the code ready to trigger an event
  3. The code only runs when triggered
  4. Pay only when your code is running


You can look at serverless as a car.

You start the car to travel to your destination.

Once you are at the destination, you stop it.

You only used fuel when driving.

Lambda works in the same way. The use is on-demand when you run the code.
