The Enterprise AI Orchestration Boundary

This article discusses the critical architectural decision of where orchestration authority should live in enterprise AI systems. It argues that teams often focus on the wrong first question—which framework to use—instead of defining clear orchestration boundaries. The article explains how orchestration controls routing, context retrieval, tool calls, state management, policy enforcement, telemetry, and failure recovery. It compares raw API calls, orchestration frameworks, retrieval frameworks, and MCP servers, emphasizing that they solve different problems and should not be mixed into a black box. A clean separation of user experience, orchestration, model access, retrieval, tools, policy, and observability is recommended. The article also highlights when raw API calls are appropriate for simple workflows and when orchestration frameworks become necessary for complex systems.
