Operator-Owned YAML for Configuration Backups

The Configuration Backup Problem Every network team has a story about a misconfiguration recovery that went sideways because the backup was stale, incomplete, or stored in some engineer’s home directory. Pulling configs from a multi-vendor environment shouldn’t require bespoke expect scripts for each platform — scripts where the TFTP timeout handling differs between your Cisco ASR edge routers and your Juniper QFX datacenter switches. When your backup logic lives inside imperative Python scripts or complex Ansible playbooks, every OS update becomes a risk. One changed CLI prompt can silently break your entire backup pipeline. ...

Operator-Owned YAML Workflows for Firmware Upgrades

The File Transfer Bottleneck in Firmware Upgrades Pushing a 2GB firmware image to 120 Arista switches shouldn’t feel like playing Russian roulette with your SSH session. Yet, most network engineers still babysit brittle Python scripts, praying a minor EOS or Junos update doesn’t break the regex parsing their pre-transfer disk space checks. Consider a typical maintenance window: you need to deploy an emergency patch across a multi-vendor spine-leaf fabric. Your automation script breaks at device 47 because an EOS update altered the dir command’s output format, causing your pre-transfer free-space check to fail. Each vendor demands bespoke expect scripts, and every OS update becomes a maintenance window risk. ...
