OpenConfig
OpenConfig is an open-source initiative and set of data models for network configuration and management, primarily used in telecommunications and data center networks. It defines vendor-neutral, standardized YANG models to automate and simplify network operations through programmatic interfaces like gNMI and gRPC. The goal is to enable consistent, model-driven network automation across multi-vendor environments.
Developers should learn OpenConfig when working in network automation, DevOps for networking (NetDevOps), or managing large-scale, heterogeneous network infrastructures. It's essential for automating configuration, telemetry collection, and operational tasks in modern networks using tools like Ansible, Python scripts, or custom applications, reducing vendor lock-in and improving interoperability.
