If you’re building applications or preparing for system design interviews, you’ve probably heard about Monolith and Microservices.
But most explanations stay theoretical.
In this video, I break it down using a real-world system flow—what actually happens when a user clicks “Place Order”… and how that flow behaves in a monolith vs microservices architecture.
You’ll learn:
How monolith systems work internally
How microservices handle the same flow across services
The real difference: function calls vs network calls
When to choose monolith vs microservices
Why microservices add flexibility—but also complexity
This is not just a definition video—this is about how systems behave in the real world.
