# Infrastructure Overview

<Info>
  This guide provides a comprehensive overview of AgentArea's infrastructure architecture, deployment patterns, and best practices for running a scalable AI agents platform.
</Info>

## 🏗️ Architecture Overview

AgentArea follows a microservices architecture designed for scalability, reliability, and maintainability:

    end
    
    subgraph "Ingress Layer"
        B --> C[Traefik/Nginx Ingress]
        C --> D[SSL Termination]
