In the era of digital IT enabled by cloud computing and fuelled by artificial intelligence and machine learning, networks which are the core backbone of the digital IT landscape are also not untouched.
New networking technologies such as Software Defined Networking (SDN), Client Based Network (CBN) and Network Virtualization (NV) have taken over traditional networking.
Network automation tools enable management, deployment, configure, operate and troubleshoot any physical or virtual network devices. As the number of devices are increasing and the digital IT landscape is spreading across physical boundaries, use of multi-cloud environments, hybrid clouds manually managing and operating networks is not feasible and wherein automation comes handy.
In this article we will learn more in detail about 10 top network automation tools, their key features and compare them.

What are Network Automation Tools?
Increased penetration of network devices, expansion of networks from one building to across geographies, mix of physical and virtual network devices requires a more advanced management of them using automation tools to achieve efficiency, speed and agility.
Network automation is achieved in three ways:
- Script based – automation is done using scripting languages and programming
- Software based – automation is done using software
- Intent based – automation is done using artificial intelligence and machine learning
