LLM Gateway Architecture: Unified Routing, Fallback & Rate Limit Management
Architect a centralized API gateway (Portkey, LiteLLM) to manage provider failover, team quotas, and unified audit logs across your enterprise.
Automatic Provider Failover
If OpenAI encounters an outage (500 error), the LLM Gateway transparently re-routes the prompt to Google Gemini or Anthropic Claude within 50ms without user disruption.
