AWS refers to Lambda as a serverless computing service. Let’s understand what server-less is. It has the following three main characteristics —

• Pay for the services you use.
• You don’t have to manage the infrastructure.
• You can scale the service automatically up and down.

AWS lambda lets the user to run code without provisioning or managing servers and the user needs to pay for how much they use. The user can also scale it up and down according to their needs.

To make AWS lambda work, following three steps should be considered —

1. Upload code to AWS lambda.
2. Set the triggers.
3. Run the code.
