Network as Code: Your Infrastructure is Still Configured by Hand. That's a Problem.

83% of network outages are caused by human configuration errors. Yet most organizations still manage their networks through CLI sessions and tribal knowledge locked in individual engineers' heads.

NetDevOps changes that.

What Network as Code actually means

Your network configuration lives in a Git repository. Changes go through pull requests. Pipelines validate, test, and deploy automatically. No more snowflake devices. No more undocumented one-off commands. Every change is versioned, reviewed, and fully auditable.

The core toolchain

• ANSIBLE Declarative playbooks describe your desired network state. Push configurations to hundreds of devices simultaneously. Idempotent by design — running it twice never causes drift. Supports Cisco, Juniper, Arista, and Palo Alto natively.
• GITOPS Git becomes the single source of truth for your entire network. Every config change is a commit. Rollbacks are a git revert. Audit trails are built in. Peer review is mandatory. The state you see in Git is the state running in production.
• NAPALM Network Automation and Programmability Abstraction Layer with Multivendor support. A unified Python API across all major vendors. Retrieve facts, compare configurations, and push changes through a single interface regardless of what hardware runs underneath.
• BATFISH Pre-deployment network validation through model-based analysis. Upload your configurations, run queries, detect routing loops, access control violations, and reachability failures before a single packet is touched. Catch the misconfiguration before it becomes the outage.

What this eliminates

Configuration drift between devices that should be identical. Emergency changes applied at 2AM that nobody documented. Outages introduced by untested modifications. Compliance audits requiring manual inspection of every device. Knowledge siloed in one engineer who is no longer at the company.

A real scenario

A firewall rule change that previously required a maintenance window and two hours of manual work becomes a pull request. Batfish validates correctness before deployment. A peer reviews the diff. The pipeline deploys in minutes. The commit message is the change record.

The security angle

NetDevOps is not just an operations story. Configuration correctness is a security control. Unauthorized changes become detectable. Drift from approved baselines triggers alerts. Least-privilege access to production devices becomes enforceable.

The network is no longer exempt from the engineering discipline applied to application code.
