Reachability Analyzer is an Amazon Web Services (AWS) tool designed to assess and diagnose network connectivity issues within a virtual private cloud (VPC) environment. It helps analyze and verify the reachability and connectivity between various resources such as EC2 instances, load balancers, databases, and other services in an AWS network.
In this Cloud Lab, you’ll initially create two EC2 instances to deploy a React application, designating one instance as the frontend and the other as the backend. The application’s frontend will be accessible from the internet while ensuring the backend remains inaccessible. For this intent verification, you’ll use Reachability Analyzer and understand the status of the path between the internet gateway and the backend instance.
Finally, you’ll verify the connectivity status between the frontend and backend instances. Upon identification of any connectivity issues between the frontend and backend instances, the Cloud Lab will guide you through the troubleshooting steps.
