Corporate Network Automation with Ansible

Uber has established a comprehensive automation strategy for its global corporate network (Corpnet) using Ansible. This initiative addresses the challenges of managing a large, diverse, and geographically distributed on-premises network infrastructure. By leveraging Ansible, Uber standardizes configuration management across thousands of devices, including switches, gateways, and firewalls, from multiple vendors. The system employs a 'Daily Nightly Enforcement' process that includes backing up existing configurations, generating desired configurations based on inventory and templates, and pushing these configurations to devices. This ensures a stable and versioned network state, overwriting any untracked manual changes.
