Software Architecture

bookArchitectural Design Principles

Design principles form the backbone of strong, scalable, and maintainable software systems. Key principles include separation of concerns, abstraction, and modularity, which help in designing clear and reusable components. Critical system qualities such as scalability, maintainability, and performance must be considered, along with the trade-offs architects face during design.

Separation of Concerns (SoC)
expand arrow

This principle encourages dividing a system into distinct sections, each handling a separate responsibility. This makes systems easier to understand, develop, and maintain.

Abstraction

Abstraction allows you to focus on high-level functionality while hiding internal implementation details. Think of using a Send Email function without needing to know how SMTP works behind the scenes.

Modularity
expand arrow

Modularity promotes building software in pieces (modules), making it easier to test, replace, and scale individual components without affecting the whole system.

Scalability
expand arrow

A well-architected system can grow in capacity. It can handle more users, data, or request without major changes.

Maintainability

Systems should be easy to modify or extend. Following clean code practices and organizing code well reduces the effort required for future updates.

Performance

Performance measures how fast and efficiently your software works under load. Architectural decisions, like caching, data storage strategies, or service boundaries that can impact performance.

Trade-offs

No architecture is perfect. You often face trade-offs, choosing performance over flexibility, or security over speed. A good architect makes informed decisions based on the system's priorities.
