Design Microservices Architecture with Patterns and Principles - Problem: Highly Coupling Dependent Layers

The video tutorial discusses the evaluation of a layered architecture, identifying issues such as high coupling and dependencies between layers. These dependencies hinder flexibility and maintenance, especially when changing frameworks. The tutorial illustrates these problems with a visual representation of layer dependencies. To address these issues, the video introduces solutions like clean architecture and the dependency rule, aiming to reduce coupling and improve code flexibility.

What is the initial step in evaluating a layered architecture?

• Ignoring potential drawbacks

• Designing, adapting, and evaluating the architecture

• Implementing new features

• Focusing solely on the UI layer

What is the main issue identified with the current architecture?

• High coupling and dependency between layers

• Lack of documentation

• Too many layers

• Excessive use of ORAM tools

Why is high coupling between layers problematic?

• It makes the code more readable

• It simplifies the architecture

• It makes the code hard to maintain and change

• It reduces the number of layers

What is one of the proposed solutions to address high coupling?

• Increasing the use of ORAM tools

• Adding more layers

• Using clean architecture and the dependency rule

• Removing the business layer

How can flexibility be achieved in the code base?

• By increasing the number of dependencies

• By focusing only on the UI layer

• By using tightly coupled services

• By organizing the code with loosely coupled services
