Design Microservices Architecture with Patterns and Principles - Evaluate: Modular Monolithic Architecture with SPA

The video tutorial discusses the architecture of a single-page application (SPA) for an e-commerce platform, highlighting the separation of UI, frontend, and backend components. It outlines the benefits of the current design, such as ease of development, debugging, deployment, and flexibility. However, it also addresses the drawbacks, particularly scalability issues due to a monolithic backend and a single relational database that becomes a bottleneck. The tutorial emphasizes the challenges of scaling databases compared to stateless application servers and provides an example of scaling difficulties during peak times, like a discount season.

What is one of the main benefits of separating the UI, front end, and back end in a single-page application architecture?

• Reduced flexibility in UI design

• More difficult to update the front end

• Easier debugging and deployment

• Increased complexity in development

What is a major drawback of the current architecture discussed in the video?

• The relational database becomes a bottleneck

• The back end is too flexible

• The UI is not separated from the back end

• The front end cannot be scaled horizontally

Why is it difficult to scale the database in the current architecture?

• The database is already scaled horizontally

• Application servers store state, complicating scaling

• Databases store state, making them harder to scale

• Databases are inherently stateless

During a peak time like a discount season, what is a challenge faced by the current architecture?

• The entire application must be scaled, not just specific modules

• The front end cannot handle increased traffic

• Only the reporting module can be scaled

• The order module cannot be scaled at all

What is a limitation of the monolithic architecture during peak periods?

• The entire application must be scaled, even if only one module needs it

• The architecture has no scalability issues

• Modules can be scaled independently

• The database can handle unlimited requests
