Could you explain what is meant by architectural design patterns of systems?

Architectural design patterns for systems are proven solutions over time for organizing the structure and interaction of components in software systems. They help create scalable, maintainable, and reliable applications by establishing common principles of architecture.

Examples of architectural patterns:

• Model-View-Controller (MVC) — dividing the application into three parts: model (data), view (interface), and controller (interaction logic).
• Microservices — splitting the system into independent services that interact via APIs.
• Layered architecture — dividing into layers (presentation, business logic, data access), each responsible for its own task.
• Event-Driven Architecture (EDA) — interaction of components through events.

Using such patterns helps standardize the approach to design, facilitates understanding of the system, and simplifies its development.
