Description

AWS Lambda is the core service for building Serverless applications in AWS. It allows you to create functions that are executed in response to events. You only pay for the time the function is executing. You can monitor functions and attach a wide variety of event triggers. You only have to select the runtime for the function you are creating and then you can start writing your code. The only limitation was that you had to use one of the supported programming languages that AWS provided by default. Well, this is no longer the case. Now you can create Lambda functions written in any kind of language by providing a custom runtime that allows the Lambda function to run code in the language of your choice. In this lab, you will be guided into the creation of a Lambda Layer which will contain the runtime configuration and the creation of a function that executes Bash shell commands.

Lab Objectives

Upon completion of this Lab you will be able to:

  • Create a Lambda layer and deploy the custom runtime the function will run on
  • Create a Lambda function written in Bash associated with the layer
  • Test the Lambda function

Lab Prerequisites

You should be familiar with:

  • Working at the command-line in Linux
  • Basic concepts of AWS Lambda
