FCR: Open source command runner for network devices

What this post added

This post introduces FBNet Command Runner (FCR), an open-source command runner for network devices. FCR addresses the challenges of automating operations on a large, multi-vendor network by providing a unified Thrift interface for running commands, abstracting away vendor-specific details and connection management. It is integrated with the Robotron system for active monitoring and can also be used for provisioning and deployment, significantly improving the efficiency and reliability of network operations at scale.
