Before writing a single test case or automation script, every professional automation engineer must understand how the application works.

In this lesson, we'll walk through a real enterprise application and learn how its architecture is designed in modern cloud environments.

You'll understand how frontend applications communicate with backend services, how APIs connect different systems, how microservices are structured, and how AWS Lambda powers serverless applications.

This foundational knowledge will help you build better automation frameworks, write more reliable tests, and become a stronger SDET.
