How to Build a Network Automation Stack From The Ground Up

on YouTube ↗41m

" summary

Goes from zero automation to two data centers, a global backbone and multiple PoPs in months by building a concrete stack: NetBox as source of truth feeding an event/workflow bus, Ansible for templated device configuration, and a middle “device roll” processor that flattens relational queries so device lookups complete in seconds. Adds a custom collector that tags metrics into a time‑series DB, reconciles 60+ redundant alerts down to meaningful events, runs locally in containers, and proves repeatable in production deployments.
