Overview

The lab provides a basic explanation of AWS Lambda. It will demonstrate the steps required to get started to create a Lambda function in an event-driven environment.

AWS Lambda is a compute service that runs your code in response to events and automatically manages the compute resources for you, making it easy to build applications that respond quickly to new information. AWS Lambda starts running your code within milliseconds of an event such as an image upload, in-app activity, website click, or output from a connected device. You can also use AWS Lambda to create new back-end services where compute resources are automatically triggered based on custom requests.

Topics covered

By the end of this lab you will be able to:

  • Create an AWS Lambda function
  • Configure an Amazon S3 bucket as a Lambda Event Source
  • Trigger a Lambda function by uploading an object to Amazon S3
  • Monitor AWS Lambda S3 functions through Amazon CloudWatch Log

Prerequisites

Familiarity with Amazon S3 would be beneficial.

Start Lab

  1. At the top of your screen, launch your lab by choosing Start Lab

This starts the process of provisioning your lab resources. An estimated amount of time to provision your lab resources is displayed. You must wait for your resources to be provisioned before continuing.

If you are prompted for a token, use the one distributed to you (or credits you have purchased).

  1. Open your lab by choosing Open Console

This automatically logs you in to the AWS Management Console.

Do not change the Region unless instructed.

Common Login Errors
