You can work toward network automation!

Businesses worldwide are looking to leverage technology to improve daily operations. Additionally, companies have more users and use cases. As a result, enterprise networking is getting convoluted. This increasing network complexity hinders growth and affects businesses. So what is the solution? Network automation! Automation allows you to automate manual, cumbersome tasks in networking. It also helps in standardizing the network structure. Finally, automation will help build a more reliable enterprise network. 

In this article, I’ll be walking you through network automation. I’ll also show you how it works and what benefits it provides your business. You’ll also learn some best practices for automation. Finally, you’ll see the top vendors to consider when automating your network. 

But first, let’s find out more about network automation.

What Is Network Automation?

Network automation is the process of using software to manage network resources and services. You can achieve network automation through a software-defined network (SDN). An SDN introduces network virtualization capabilities. This makes it easy to automate and control the networks

Network automation also can help you configure, test, deploy, and operate components in your network. Since enterprise networks are becoming more complex, network automation tools are gaining traction. Here are some of the things these tools can do:

  • Automate the network provisioning 
  • Perform network planning, designing, and implementation
  • Supply virtual and physical networking devices or nodes 
  • Implement security compliance and improve the overall network security
  • Simplify network management
  • Automate reporting, monitoring, and management of enterprise network
  • Analyze real-time network data to deliver insights

To better understand what network automation is, let’s look at how it works.

How Does Network Automation Work?

Generally, you automate networks with programmable logic on the devices’ command line interface (CLI). This way, the nodes can dynamically perform automated actions. These include network filtering, port controlling, bandwidth control, etc. 

However, this method isn’t scalable. It also limits the scope of automation as it needs to be done on a per device basis. As a result, most modern networking infrastructures offer a centralized control panel. This panel will connect all the networking devices within the network.

Automating different parts of your systems!

Network administrators or programmers can create programmable logic and scripts. This way, they can control and automate your network. To do this, they can use the devices’ CLI or graphical UI. Alternatively, admins can rely on external systems or automation tools. After that, programmers can execute these scripts using the CLI or API. 

Automation tools and services can help you automate several everyday networking tasks. For instance, they can help you analyze and predict bandwidth usage. Automation will also help you with network inventory management and dynamic provisioning. You’ll also be able to backup and change configurations across your business. Finally, network automation tools can help you remotely control access points and ports.

Now that you understand how network automation works, let’s look at some of its benefits. 

Benefits of Network Automation

Generally, growing companies can’t manage and scale their infrastructure easily. But network automation helps you overcome this challenge. In turn, you’ll also improve your overall efficiency. Let’s take a more detailed look at the benefits of network automation:

  • Eliminates manual tasks. This results in an increase in accuracy and efficiency. 
  • Standardizes processes. This reduces the risks of network outages and scalability issues.
  • Monitors your network constantly and generates reports. This can help you better control your network infrastructure.
  • Makes changes faster and builds a reliable network.
  • Gives you network visibility and ease of control through a centralized dashboard.
  • Tracks, analyzes, and resolves issues.
  • Reduces human errors. This increases network resilience.
  • Reduces the workload on IT staff. This can help organizations save capital costs.

You should follow some best practices to harness the benefits of network automation. Let’s take a look at those now. 

Best Practices for Network Automation

Network automation tools and services use software abstraction. They connect networking devices and nodes. This way, they give you an easy-to-control network management workflow. Here are some best practices you can adopt to get the most out of network automation: 

Decide What to Automate

Often, companies aren’t attentive when selecting a network automation vendor. This is a huge mistake. Before you start choosing a vendor, know what you need to automate in your network. This will help you narrow down your search list for the vendor. It’ll also help you save costs. 

Aim for Low-Code Network Automation

The industry faces several challenges with the network automation skill gap. In fact, programming experience is lacking. Network scripting also has a steep learning curve. Did you know that only 3% of networking teams know how to perform automation tasks? So, choosing a service that allows low-code network automation could prove to be very beneficial. This will eliminate the dependency associated with certain employees. Low-code network automation will also limit human errors

Adopt a Vendor-Agnostic Approach 

Often, network architectures include solutions from many vendors. This means you should design a vendor-agnostic network orchestration. This mitigates the overhead associated with fixing errors or making changes to your network. Alternatively, you can find and deploy automation tools that support different vendors. This way, you can implement a true single view multi-vendor support.

Integrate with Other Tools and Services

It’s important to choose a service that integrates directly with external systems. For instance, integration with ELK and ServiceNow helps with log management and incident reporting. If your service has broad API integration support, you can streamline your business operations. You’ll be more flexible and you’ll use external tools to fit your needs.

Automate Configuration

If you automate configuration, you’ll ensure consistency across all your applications. You’ll also mitigate human errors. This enables your network admins to convert the configuration into software code. In turn, you can build a single source of truth for all configurations across your organization. 

Next, let’s take a look at some of the industry’s most commonly used network automation tools.
