This video (0:00 - 34:05) features Mr. Narendrababu, a technical expert with over 17 years of experience, explaining the fundamental differences between Monolithic and Microservices architectures using an e-store project as a real-time example. He guides viewers through the pros, cons, and business impact of choosing one over the other for system design.
Monolithic Architecture (0:55 - 16:13)
Mr. Narendrababu defines this as a single-tiered application where all components (user module, product module, order module, registration) are packed into a single project and deployed on one server (1:32 - 4:43).
Major Disadvantage: If one module fails, the entire application goes down, causing massive revenue losses (4:55 - 6:13).
Deployment Issue: You cannot deploy until every module is finished. If one team is delayed, the entire project is delayed (11:58 - 14:15).
Microservices Architecture (14:15 - 25:05)
This approach breaks the application into independent, smaller services (product, basket, order, user), each with its own database (17:26 - 21:28).
Major Advantage: If the order service fails, the user can still browse products. Only that specific service is affected, not the whole system (21:40 - 22:04).
Database Flexibility: Different databases can be used for different needs (e.g., MongoDB for catalog, PostgreSQL for transactions, Redis for caching) (22:30 - 23:15).
Communication: An API Gateway connects all services and handles requests from mobile, tablet, and desktop applications (23:20 - 24:35).
Real-Time Implementation & Demo (25:05 - 34:05)
Containerization: The speaker demonstrates using Docker Desktop to deploy services independently (25:35 - 29:35).
Future Deployment: The final goal is to deploy these containers into Azure AKS (29:20).
Code Structure: He briefly shows a clean code structure utilizing CQRS (Command Query Responsibility Segregation) and middleware (30:00 - 31:00).
