What types of architectures have you encountered?

I have encountered several types of architectures:

• Monolithic architecture — all system components are tightly coupled and deployed as a single application.
• Client-server — separation into client and server parts, interacting over a network.
• Microservices architecture — the system is divided into independent services that communicate via APIs.
• Layered architecture — separation into levels (presentation, business logic, data), which simplifies maintenance and development.
• Event-driven architecture — components interact through events, increasing scalability and flexibility.

Each architecture is chosen depending on the project requirements, scalability, and ease of maintenance.
