Architectural Design

What it is:

• The high-level structure of a software system.
• Defines how components interact, how the application is deployed, and how data flows.
• Focuses on scalability, performance, modularity, and maintainability.

Examples

• Monolithic vs Microservices
• Layered architecture (Presentation → Business → Data)
• Event-driven architecture
• Hexagonal (Ports and Adapters), Onion, Clean Architecture
• Use of components: databases, message queues, APIs, frontends
