Network Automation vs Network Configuration Management: Complementary Roles in the Network Lifecycle

Network automation and network configuration management (NCM) are often conflated. Many engineers assume that automating device configuration is the same as configuration management, or that one discipline can replace the other. In reality, they are two halves of the same lifecycle.

Network automation is what you do to the network: provisioning, pushing changes and orchestrating services. NCM is what you do before and after automation: maintaining a system of record, backing up configurations, enforcing policies and verifying that changes delivered the desired outcome. When you pair these disciplines effectively, you get a resilient network that evolves quickly and safely.

If you want the full framework and buyer-level perspective on how these two areas fit together, start with Network Automation vs. Configuration Management.

Defining the Two Disciplines

What Is Network Automation?

Network automation uses software platforms and scripts to perform routine tasks such as provisioning devices, deploying configuration changes, monitoring state and remediating issues without manual intervention. Modern automation approaches reduce human error and improve network reliability by making change repeatable, testable and scalable across environments.

The best network automation programs don’t just push changes. They also standardise how changes are created, scheduled, validated and verified so the network can evolve quickly without turning every maintenance window into a high-stress event.

What Is Network Configuration Management?

Network configuration management (NCM) is the process of maintaining a trusted record of your network devices and their configurations, and then using that record to enforce standards, track change and prove compliance. NCM typically includes device discovery, automated configuration backups, version history, policy checks and audit reporting.

In practice, modern Network Configuration Management (NCM) is automation-first by design: it continuously captures state, detects drift and applies guardrails so change is safer and easier to govern.

How They Complement Each Other

Network automation focuses on execution: using scripts, workflows or platform-driven automation to push changes and provision services across devices. NCM focuses on governance: knowing what the network looks like, keeping configurations backed up, tracking versions and ensuring policies are enforced.

Without NCM, automation becomes brittle because there is no authoritative source to inform scripts or validate outcomes. Without automation, NCM becomes tedious and reactive because changes are made manually and errors creep in. Together, they create a virtuous cycle:

• Before automation: NCM discovers devices, records baseline configurations and defines compliance policies. Backups are scheduled and version control is in place, ensuring there is a reliable state to revert to.
• During automation: automation workflows use the NCM system of record as a source of truth. Changes are pushed across devices using consistent templates and policy-aware rules, while monitoring tracks progress and flags deviations.
• After automation: NCM validates results, records the new versions and triggers remediation or alerts if drift occurs. Audits and reports demonstrate compliance and inform the next automation cycle.

Why the Distinction Matters

Conflating network automation with configuration management leads to risk. If you treat automation as a replacement for NCM, you might run scripts without first backing up devices or enforcing compliance policies. When something goes wrong, you have no reliable record of what changed, what the baseline was or how to roll back cleanly.

On the other hand, using NCM without automation limits how quickly you can scale. Manual configuration is slow, inconsistent and error-prone. Modern networks with cloud and edge components are too dynamic to manage through one-off changes and tribal knowledge. Automation is how you keep pace, and NCM is how you keep it safe.

Breaking Down the Differences

The Network Automation Lifecycle

1) Inventory and baseline

Use NCM to discover devices and collect baseline configurations. This inventory becomes your source of truth. When your device data is accurate, automation becomes safer and far more repeatable.

2) Policy and template creation

Define configuration standards, compliance rules and reusable templates. Good policy design is what makes automation consistent across teams and sites, and prevents “snowflake” configurations from creeping into production.

3) Backups and version control

Schedule automated backups and maintain version history in a central repository. Backups are your safety net, and version history is your change narrative. If backup and recovery are core priorities for your organisation, start with Automated Configuration Backup and Config Restore to improve recovery speed and reduce mean time to repair.

4) Automated execution

Use automation workflows to apply configuration changes, perform bulk updates, standardise rollout patterns and remediate drift. This is where network automation typically gets the spotlight, but it works best when execution is anchored to a reliable system of record.
