OpenTelemetry does not replace Prometheus. They solve different problems, they are converging, and understanding the boundary between them will save you from expensive architectural mistakes.

Puppets and Octopi: Why Top-Down Orchestration Hits a Wall

Centralized, imperative orchestration requires centralized coordination, and centralized coordination is a bottleneck that doesn't scale. Distributed, declarative convergence pushes intelligence to the edges.
