What Skills Do You Need for a Career in Network Automation?

Introduction

The world of networking is evolving rapidly, and automation is at the forefront of this transformation. If you're considering a career in network automation, you need the right skills to succeed. This article will explore the key skills required and how you can develop them to build a successful career in this field.

What Exactly is Network Automation?

Network automation refers to using software and scripting to manage and control network functions, reducing manual effort and minimizing human errors. With the increasing complexity of modern networks, automation plays a crucial role in streamlining operations, improving efficiency, and enhancing security.

Why Network Automation is Important?

• Efficiency: Reduces the time needed to configure and manage networks.
• Consistency: Ensures uniformity in network configurations.
• Scalability: Helps manage large-scale networks with ease.
• Security: Reduces human errors, preventing security vulnerabilities.
• Cost Reduction: Minimizes operational costs by reducing manual interventions.

The Key Skills You Need for Network Automation

To build a career in network automation, you need a combination of technical and soft skills. Below are some of the most crucial skills:

1. Solid Networking Basics

You can’t automate a network if you don’t understand how it works in the first place. That means getting familiar with the following:

• IP Addressing and Subnetting – the foundation of networking.
• Routing Protocols (like OSPF, BGP, EIGRP) – these help you route traffic efficiently.
• Network Security Basics – understanding firewalls and securing your network is key.
• VLANs, Switching, and Advanced Concepts – if you want to tackle larger networks, you’ll need to know things like MPLS and SD-WAN.

These foundational skills will help you automate the right processes and troubleshoot when things go wrong.

2. Programming and Scripting Skills

In network automation, you’ll need to write scripts to automate tasks. The good news is that Python is the go-to language for this field. It’s easy to learn and has a huge range of libraries that make it perfect for automation.

But Python isn’t the only tool in your toolbox. Depending on your environment, you may also need to know:

• Bash for Linux systems.
• Go and Perl for specialized frameworks.
• PowerShell if you’re working in a Windows network.

The more languages you’re familiar with, the more versatile you’ll be.

3. Mastering Automation Tools

Automation tools are at the heart of network automation. Some of the most popular ones include:

• Ansible: A tool that helps with configuration management across devices.
• Terraform: Ideal for infrastructure-as-code (IaC) if you’re automating cloud infrastructure.
• Netmiko and Paramiko: Libraries used to automate tasks over SSH.
• NAPALM: A platform that standardizes automation across different vendors.
• Puppet and Chef: Other configuration management tools you might encounter.

Learning these tools will be essential in streamlining your work and automating networks at scale.

4. Working with APIs and Network Protocols

Many network devices offer APIs that allow you to automate configuration and monitoring tasks. Some protocols and technologies you should understand include:

• RESTful APIs: The most common way to interact with devices.
• SNMP: A protocol used for monitoring networks.
• NETCONF/YANG: Used for managing configurations.
• gRPC: A protocol for high-performance communication between systems.

Knowing how to interact with these protocols will be vital for automating tasks like monitoring or device configuration.

5. Understanding Cloud Networking & DevOps

Since more and more networks are moving to the cloud, it’s important to know how cloud-based networks work. You should get comfortable with:

• Cloud networking platforms like AWS, Google Cloud, and Azure.
• CI/CD pipelines for continuous integration and deployment.
• Containerization using Docker and Kubernetes.
• Infrastructure as Code (IaC) for managing cloud resources.

Having a solid grasp of these concepts will allow you to automate cloud networks effectively.

6. Network Virtualization and SDN

• Understanding of Software-Defined Networking (SDN).
• Network function virtualization (NFV).
• VMware NSX and Cisco ACI for virtual network automation.

7. Problem-Solving and Analytical Thinking

Network automation engineers must be able to troubleshoot automation failures and design efficient network automation workflows.

8. Linux and System Administration

• Basic Linux commands and shell scripting.
• Managing servers and networking components in Linux environments.
• Configuration management using tools like Ansible and Puppet.

Certifications and Training

Enrolling in a network automation course can help you develop essential skills and gain certifications that are recognized in the industry. Several online platforms, including PyNet Labs, offer specialized courses focused on network automation, where you can learn Python, Ansible, and other important tools. These courses typically cover both foundational and advanced concepts, equipping you with the practical experience needed to succeed in network automation.

Some of the popular courses include:

By completing a network automation course, you'll gain hands-on experience and be well-prepared to tackle automation challenges in real-world network environments.

Gaining Practical Experience

Hands-on experience is vital for mastering network automation. You can gain practical knowledge by:

• Setting up virtual labs – Use GNS3, Eve-NG, or Cisco Packet Tracer.
• Working on real-world projects – Automate network tasks at your workplace.
• Contributing to open-source projects – Helps improve your expertise and gain recognition.
• Using DevNet Sandboxes – Cisco’s free platform for hands-on API development.
• Building Home Labs – Set up routers, switches, and virtualized environments for practice.

Additionally, taking a network automation course will offer structured learning and provide you with guided practical exercises to enhance your skills.
