Code is the new CLI - Data Networks Programmability and beyond
summary
Claim: coding replaces repetitive CLI work so a bank migration that would take weeks becomes about a week and a half using Python templates and automation. Demonstrated tools include NETCONF and YANG, REST/RESTCONF, OpenConfig models, and paramiko scripts for CLI emulation; model‑driven APIs use running/candidate/startup databases. Cited numbers: 95% of changes are manual, 70% of failures from copy‑paste, 75% of ops cost from troubleshooting. Built CI/CDable infrastructure as code with virtual network testing; automation proves effective but vendor model differences remain.
