What is Network Automation?

Network Automation has emerged as a cornerstone of modern Network management, providing the tools and processes necessary to maintain, secure, and optimize network infrastructures efficiently in this digital age.

As networks grow in complexity and scale, the necessity for automation becomes undeniable, not just to enhance operational efficiency but also to enable the rapid deployment of network services that are critical to business success and innovation.

Mastery of CCIE Enterprise Infrastructure is crucial, as it specifically addresses advanced enterprise networking solutions essential for a highly automated and programmable network infrastructure.

What is Network Automation?

Network Automation refers to the process of automating the Planning, Deployment, Management, and Operation of physical and Virtual Network Devices.

Networks can be automated with software that uses tools and technologies to perform tasks that were traditionally executed manually by Network Administrators.

This technology plays a critical role in enhancing Network functionality and efficiency, reducing human errors, and decreasing operational expenses.

How Network Automation Works?

Network Automation integrates software solutions that provide tools to manage both hardware and software network components automatically. Key functionalities include:

  • Automated Configurations: Applying and updating configurations consistently across numerous devices.
  • Orchestration: Simplifying complex sets of networking tasks by coordinating automated actions that align with business processes.
  • Provisioning and Deployment: Automatically setting up and configuring devices in the network.
Network Automation - Workflow

Types of Network Automation

Intent-based Networking (IBN):

IBN transforms high-level business policies (what you need) into network configurations (how it’s done) automatically. It ensures the network continuously aligns with business objectives, providing validation tools to guarantee compliance.

Software-Defined Networking (SDN):

SDN separates the control logic to off-device computers, allowing administrators to shape traffic from a centralized control console without having to touch individual switches.

Intelligent Network Automation:

Leveraging artificial intelligence (AI) and machine learning (ML), this sophisticated type automates the decision-making process in network management, helping to predict potential disruptions and optimize network operations proactively.
