Architecture Patterns

Software architecture patterns, system design principles, and architectural decision records (ADRs) for building scalable, maintainable systems.

System Design

Patterns for designing distributed systems, microservices, and cloud-native applications.

Design Patterns

Implementation examples of classic and modern design patterns with practical use cases.

Architecture Decision Records

Documentation of significant architectural decisions and their rationale.

Diagrams & Visualizations

System architecture diagrams using Mermaid for clear visual communication.

Example: Microservices Communication Pattern

graph TB
    subgraph "API Gateway"
        GW[Gateway]
    end

    subgraph "Services"
        AUTH[Auth Service]
        USER[User Service]
        ORDER[Order Service]
    end

    subgraph "Message Queue"
        MQ[RabbitMQ/Kafka]
    end

    subgraph "Data Layer"
        DB1[(User DB)]
        DB2[(Order DB)]
        CACHE[(Redis)]
    end

    GW --> AUTH
    GW --> USER
    GW --> ORDER

    USER --> DB1
    ORDER --> DB2
    AUTH --> CACHE

    USER -.-> MQ
    ORDER -.-> MQ
    MQ -.-> USER
    MQ -.-> ORDER

This diagram illustrates a typical microservices architecture with: - API Gateway for unified entry point - Service-to-service communication via message queue - Dedicated databases per service (Database per Service pattern) - Caching layer for performance optimization

More architecture patterns and detailed explanations coming soon.
