The video tutorial covers the process of designing an e-commerce application architecture, emphasizing the importance of identifying both functional and non-functional requirements. It highlights the need for scalability and reliability, introducing horizontal scaling and load balancing as key solutions. The tutorial also discusses clean and multi-architecture patterns, and the challenges of scaling stateless application servers versus stateful database servers. The final architecture design incorporates these elements to handle increased concurrent user requests effectively.

Why is it important to identify non-functional requirements in architecture design?

• They only focus on the aesthetic aspects of the application.

• They are not necessary for small applications.

• They ensure the application meets performance and scalability needs.

• They help in defining the user interface.

Which architectural styles are mentioned for designing the e-commerce application?

• Monolithic and microservices

• Service-oriented and serverless

• Clean and multi-tier

• Layered and event-driven

What is the role of a load balancer in the architecture?

• To store user data securely

• To manage database transactions

• To distribute incoming requests evenly across servers

• To enhance the graphical user interface

Why is horizontal scaling applied to the application servers?

• Because they require less power consumption

• To improve the user interface design

• To reduce the cost of server maintenance

• Because they are stateless and can be easily replicated

What challenge is associated with scaling the relational database server?

• It is difficult to scale due to its stateful nature

• It is too expensive to scale

• It does not support horizontal scaling

• It requires a complete redesign of the application
