Enterprise LLM Integration Architecture

Design patterns and best practices for integrating multiple LLM APIs into enterprise systems.

Gateway Architecture

Implement an API gateway that handles authentication, rate limiting, logging, and routing across multiple LLM providers.

Key Components

  • Unified OpenAI-compatible endpoint
  • Multi-provider fallback system
  • Real-time cost tracking per department
  • Request/response logging for compliance
  • A/B testing framework

Security Considerations

Store API keys in secrets managers, implement IP allowlisting, and use mTLS for internal service communication.

Monitoring & Observability

Track latency percentiles (P50, P95, P99), error rates, cost per feature, and model quality metrics.
