🏛️ Architectural Layers
SysManage employs a layered architecture pattern ensuring separation of concerns, maintainability, and scalability.
React TypeScript Frontend: Modern single-page application with real-time WebSocket integration, responsive design, and comprehensive system management interfaces. Features include host management, package operations, script execution, and system monitoring dashboards.
FastAPI REST Endpoints: High-performance API layer with automatic OpenAPI documentation, request validation, authentication middleware, and comprehensive error handling. Supports both synchronous REST operations and asynchronous WebSocket communications.
Service Components: Core business logic handling host management, package operations, script execution, message queuing, and system orchestration. Implements complex workflows like package dependency resolution, batch operations, and state management.
PostgreSQL Database: Enterprise-grade relational database with advanced features including JSON columns, full-text search, complex indexing strategies, and ACID compliance. Handles user data, host information, package inventories, and audit logs.
WebSocket + mTLS Protocol: Real-time bidirectional communication with agents using WebSocket over mutual TLS. Implements persistent message queuing, automatic retry mechanisms, and connection health monitoring for reliable distributed operations.
Cross-Platform Agents: Lightweight Python agents running on managed hosts, supporting Windows, Linux, and macOS. Handle local operations, system monitoring, package management, and secure communication with the server.

🎯 Design Principles
Modular design with clearly defined service boundaries, enabling independent development, testing, and deployment of system components.
Optimized for speed with async operations, connection pooling, efficient database queries, and minimal resource footprint on managed hosts.
Multiple security layers including mTLS encryption, JWT authentication, role-based access control, input validation, and comprehensive audit logging.
Designed to scale horizontally with load balancing support, stateless services, efficient caching, and distributed architecture patterns.
Resilient design with graceful degradation, automatic retry mechanisms, circuit breakers, and comprehensive error handling and recovery.
Clean code architecture with comprehensive testing, detailed documentation, consistent coding standards, and automated CI/CD pipelines.
