📚 Understanding the Diagrams

Legend

• Green nodes: Management and UI components
• Blue nodes: Core infrastructure services
• Purple nodes: Orchestration and intelligence
• Orange nodes: Security and authentication
• Light blue nodes: Data storage and caching

Best Practices

1. Start with the Portal for application management
2. Use the Registry for service discovery
3. Leverage the Autogent Server for intelligent orchestration
4. Implement proper security with vault integration
5. Monitor everything with comprehensive observability

Next Steps

• Portal Setup: Begin with MCP Portal
• Registry Configuration: Continue with MCP Registry
• SDK Integration: Choose your SDK
• Production Deployment: Follow the Deployment Guide
