The video tutorial discusses the evaluation of a layered architecture, identifying issues such as highly coupled layers and challenges with framework flexibility. It highlights the problems of maintaining code and adapting to new frameworks due to these dependencies. The tutorial illustrates the dependencies between UI, business, and data layers, and proposes solutions like clean architecture and the dependency rule to address these issues.

What is the primary focus when evaluating a layered architecture?

• To add more layers

• To identify potential drawbacks

• To increase the number of dependencies

• To remove all layers

What is a major problem identified in the current layered architecture?

• Excessive flexibility

• Too many frameworks

• High coupling between layers

• Lack of layers

Why is high coupling between layers problematic?

• It simplifies code maintenance

• It reduces the number of frameworks needed

• It makes the system too flexible

• It hinders flexibility and complicates maintenance

What is one proposed solution to the problem of high coupling?

• Adding more layers

• Using clean architecture

• Increasing dependencies

• Removing all services

What does the dependency rule aim to achieve?

• Increase the number of dependencies

• Ensure layers are tightly coupled

• Lock the code to a single framework

• Organize code with loosely coupled services
