Configuring an AWS Lambda Target on an Application Load Balancer
Application Load Balancers support content-based routing and are capable of distributing traffic across multiple targets and multiple Availability Zones. One type of target that is capable of serving HTTP requests to an application load balancer is an AWS Lambda function. This allows you to build out your serverless applications using AWS Lambda, then configure an application load balancer to provide the HTTP frontend to serve your client requests.
In this lab, you will create an AWS Lambda function that will be used to retrieve an HTML file from an Amazon S3 bucket. You will also configure the necessary listener rule and target group to allow an application load balancer to invoke your function.
