“You’re either the one that creates the automation, or you’re getting automated,” said Tom Preston-Werner, the co-founder of GitHub.
Embracing automation is no longer an option; it is becoming almost a requirement in virtually any IT field.
There are hundreds of daily monotonous tasks that can be automated, from deployments, management, orchestration, securing, to monitoring. Still, many network engineers are indifferent to the impact that automation is having on the evolution of the networks (and their careers).
It is even evident in the popular network certifications that are being re-direct towards automation and Software-Defined Networks SDN. Automation is still green, but when it begins to mature, network admins and engineers will not even need to log into any router or firewall equipment.
Here is our list of the top network automation tools:
- SolarWinds Network Automation Manager – EDITOR'S CHOICE A package of SolarWinds modules that includes network monitoring and managing systems plus tools for monitoring servers and applications. Runs on Windows Server. Start a 30-day free trial.
- Syxsense Manage – FREE TRIAL A cloud-based platform that implements endpoint management for servers and desktops running Windows, Linux, and macOS and also IoT devices.
- ManageEngine Network Configuration Manager (NCM) A security and management system that corrects configuration problems on network devices, backs them up, prevents tampering, and facilitates onboarding. Available for Windows Server and Linux.
- Ansible (Tower) An automation platform from the producers of RHEL. Available for Linux, macOS, Unix, and Windows.
- Netmiko A free library of network utilities that offers functions to integrate into Python programs.
- NAPALM A Python library for network device contacts. This is fully known as Network Automation and Programmability Abstraction Layer with Multivendor Support.
- Truesight Network Automation An AIOps suite that manages underlying networks and services whether on premises, in the cloud, or both. Runs on windows.

- Apstra OS This is a virtual overlay that standardizes the management of network hardware through a single interface. Runs on top of a hypervisor.
- NetBrain Automation An adaptive network automation platform that creates an operating system for your network. Requires one Linux server and one Windows Server host.
Of course, automation will not replace human intelligence (our jobs).
With the proper automation tool, we will be able to do thousands of tasks per day, something that probably took months before.
Automation will give us more time to think about network architecture, design, and plan for its capacity.
Network Automation: A Challenge and Opportunity
Today, network operation teams still perform hundreds of manual tasks every day.
Although they know about the benefits of automation, most of them don’t know how to start.
Embracing automating in the network is not so easy; it brings new challenges:
- Network engineers need to learn some coding/scripting
- There are still no new automation standards or regulations
- Traditional networking vendors have disparate configuration commands
- There is a lack of APIs and documentation
- The network has multiple points of configuration
Although 99% of network engineers are foreigners to software development and programming languages, they will inevitably start to see their importance, especially around tools like Python, Chef, and Ansible.
Automating the network also deviates from some regulatory standards and compliance.
Existing networking designs are not automation-friendly.
Any new automated configuration can fail existing regulatory compliance.
Without standards, all networking vendors can have different configuration commands, which makes it even more difficult.
Automation is a disruptive technology.
A software bug caused a major outage in Google in June 2019, which happened due to a runaway automation process.
Google, of course, is the king of disruptive innovation.
Google knows that there will always be bugs in any new technology.
And, still, humans are far more prone to error than automated machines, when putting the config into devices.
So why use Network Automation Tools
Automation is the process of removing the human factor from the equation of workflows or processes.
For the network, labor-intensive tasks can be automated— such as configuration, monitoring, backups, security, etc.
Using the right automation tool can save companies lots of money in the process.
A significant number of network operations can also be automated.
In fact there is a new term for NetOps (or NetOps 2.0), which refers to the new approach of networking that uses the same tools and techniques used by DevOps.
With advanced automation, network engineers will likely need to be working closely with software developers to create new networking solutions.
Some examples of how NetOps can benefit from automation tools:
- Configure equipment automatically – Workstations, distribution, access, and core equipment can be configured without human interaction.
- Test the state of the network – Automated validation and testing tasks can be deployed on the network. Testing connections, new protocols, stress tests, the software can all be performed by AI.
- Compliance checks – Automation software can perform daily checks on network configurations to fulfill a set of compliance and regulation standards.
- Other routine tasks – Network automation tools can also schedule automatic network config backups and scans.

Network automation FAQs
What is network automation framework?
Network automation requires interaction with network devices. The automation software is a central controller rather than the actual implementor of adjustments to improve performance. Therefore, the network automation system can best be described as a framework. It connects to all of the switches and routers on the network to extract performance data, which is then assessed, resulting in instructions sent back to the devices.
Which language is used for network automation?
