Design Microservices Architecture with Patterns and Principles - Design Principles - Separation of Concerns (SoC)

The video tutorial discusses the principle of separation of concerns, a core design principle in software development. It explains how this principle helps manage complexity by dividing a program into distinct sections, each addressing a separate concern. The tutorial emphasizes the importance of low coupling and high cohesion for easier software control and reusability. An example of web UI development is provided, illustrating how HTML, CSS, and JavaScript are used to configure UI elements separately.

What is the main motivation for using layered architecture in software design?

• To make the software run slower

• To reduce the number of developers needed

• To increase the number of lines of code

• To manage complexity by separating concerns

How does separation of concerns help in software development?

• By combining all functionalities into a single block

• By isolating different concerns into distinct sections

• By making the code more complex

• By increasing the overlap between different sections

What is the benefit of low coupling in software components?

• It reduces the need for testing

• It increases the dependency between components

• It makes the software harder to maintain

• It simplifies control and enhances reusability

Which of the following is an example of separation of concerns in web development?

• Ignoring the use of CSS for styling

• Combining all UI elements into one script

• Separating HTML, CSS, and JavaScript into different files

• Using a single file for HTML, CSS, and JavaScript

Why is it important for components to have distinct responsibilities?

• To enhance reusability and maintainability

• To ensure components are tightly coupled

• To make debugging more difficult

• To increase the complexity of the system
