In her PyLadies talk, “Infrastructure-as-Code in a Latency-Critical Bare Metal World,” Senior Infrastructure Engineer Leanne Fok shares how we brought declarative IaC principles to physical, latency-sensitive trading infrastructure where nanoseconds matter and every cable is intentional.
Managing thousands of bare metal servers across global data centers introduces a different class of problems. There is no managed control plane. No provider APIs to rely on. Just hardware, strict performance constraints, and very little tolerance for configuration drift.
So how do you:
- Define infrastructure intent clearly enough to automate it
- Enforce standards across physical devices, ports, power, and networking
- Detect when real-world state quietly diverges from what you declared
- Build trust in automation while migrating from legacy processes
In this talk, Leanne walks through the architectural patterns we adopted, including declarative intent modeling, reconciliation loops, truth collectors, and a custom Terraform provider that translates infrastructure definitions into enforceable standards.
