Flow explaination of three-tier architecture
In the diagram below, we will see the architectural model of a fullstack application implementing three-tier architecture. First, the user operation will go through the Internet gateway and then to the External (Internet facing) Application Load Balancer. Load Balancer will forward traffic to servers in the Web tier. Then the servers in the Web tier will call APIs to the Interal Load Balancer. Load Balancer will then forward traffic to servers in the App tier. Finally, the servers in the App tier will process the request, retrieve data in the Data tier (if necessary) and return results to users in the Web tier. This is the basic three-layer architectural model that we will implement in this workshop.
