Software Architecture Fundamentals
Master the principles of designing scalable systems, selecting appropriate architectural patterns, and creating maintainable software foundations.
Core Principles
SOLID Principles
Object-oriented design principles ensuring maintainability through single-responsibility, open/closed, and Liskov substitution patterns.
DRY/KISS
Design patterns minimizing code duplication (DRY) while maintaining simplicity (KISS) for easier maintenance.
Modern Architectures
Monoliths
Traditional unified codebase pattern with tightly-coupled components and centralized deployment.
Microservices
Decoupled architecture pattern with independent services sharing common infrastructure and APIs.
Serverless
Cloud-based architecture abstracting infrastructure management through pay-per-use execution models.
Architectural Challenges
Scalability
Architecting for performance under load with horizontal scaling, load balancing, and distributed systems patterns.
Includes topics: CAP theorem, rate limiting, sharding
Security
Building secure systems through proper authentication, encryption, and threat modeling at design phase.
Includes topics: zero-trust architecture, penetration testing
