How We Built an Automated Data Center Network in Less Than 6 Months
summary
Automated a colo data center (USW1) in under six months by modeling and validating designs for three months then racking and deploying in 2.5 months. Uses Cisco Modeling Labs for full-network simulation, Cisco NSO plus Python templates to generate device configs, Git for versioned source-of-truth, and a dev test pre-prod production pipeline. Fabric spans Nexus, UCS, ASR1000, ASA/Firepower, VMware and Kubernetes; automation spins up 200 pods in <5 minutes. Performance tuning and scope cuts are ongoing.
