How do you organize the separation of responsible components in system architecture?

The separation of responsible components in system architecture is usually based on the principles of modularity and the Single Responsibility Principle.

To achieve this:

• Define the main business functions and allocate a separate module or service for each.
• Use a layered architecture: for example, a presentation layer (UI), a business logic layer, and a data access layer.
• Each component is responsible for its own area of responsibility and interacts with others through well-defined interfaces.
• Apply design patterns such as MVC, Service-Oriented Architecture (SOA), or microservices if the system is large.

This approach facilitates maintenance, testing, and scaling of the system.
