What is Network DevOps? What is NetDevOps?

What is Network DevOps?

Network Devops is the acceptance of DevOps culture and principles in network engineering and operations, also referred to as NetDevOps & DevNetOps, Network DevOps is the movement towards using DevOps culture and principles when operating network infrastructure.

NetDevops is a blend of Network, Development, and IT Operations, utilising version control and automation, with tools like Ansible, Python, Git, Github, Terraform and Jenkins. Network engineers need to think more like programmers and treat their network like code. Infrastructure as Code is the way to manage your network in 2025 and beyond.

With so many networks operating in the cloud now, without getting on board with DevOps principles managing the complex network infrastructures in use today is going to become more difficult.

The big question is What is Network Devops?

What is NetDevOps?

NetDevOps is a modern approach that integrates network engineering and operations with DevOps practices to enhance collaboration and efficiency.

NetDevOps is focused on automating network management tasks, allowing teams to deploy and manage network configurations more rapidly and reliably.

NetDevOps and Network DevOps are basically the same thing but with so much terminology around it’s hard to know which one to use. Cisco seem to favour the term NetDevOps but Netwwork DevOps is the same thing!

So what is Network Devops and what does a Network Devops Engineer do?

What is a NetDevOps Network Engineer?

A new role has been created, a role which did not exist a few years ago. A network engineer who understands automation and DevOps tools is the network engineer of today, a NetDevOps engineer.

Not only do network engineers need to know how to configure and design networks, they also need to understand how to provision and operate those networks using DevOps tools.

DevOps for Network Engineers

NetDevops engineers need to know about Ansible, Python, API’s Git, GitHub, GitLab, Terraform and CI/CD pipelines.

The list is endless of tools and technologies but a good understanding of the above will stand you in good stead for the future.

Whilst good developers do not traditionally have knowledge of networks and network engineers did not have knowledge of software, the two skillsets are merging now.

So what does a day in the life of a NetDevOps engineer look like? What is NetDevOps all about?

What are the benefits of NetDevOps?

NetDevOps, or Network Development Operations, is a framework for network automation and management inspired by the principles of DevOps. DevOps has been instrumental in transforming the software development lifecycle by bringing development and operations teams closer together to facilitate faster and more reliable software delivery. NetDevOps applies the same principles to network management, resulting in numerous benefits:

1. Faster Deployment and Scalability: Using automated tools and standardized procedures, networks can be deployed, scaled, and managed more quickly and efficiently.
2. Improved Collaboration and Efficiency: Just as DevOps improves collaboration between software developers and operations teams, NetDevOps promotes better collaboration between network engineers and IT operations, resulting in improved efficiency and communication.
3. Increased Network Reliability: Automated testing and deployment in NetDevOps can reduce errors and downtime. Problems can be detected and corrected more quickly.
4. Continuous Improvement: The use of modern software development practices such as CI/CD (Continuous Integration/Continuous Deployment) in the network domain allows for incremental, rapid improvements to the network.
5. Improved Security: Automated deployment processes can ensure that security policies are applied consistently across the network. In addition, security can be integrated into the network management process, rather than being an afterthought.
6. Reduction in Manual Processes: With automation as a key aspect of NetDevOps, time-consuming and error-prone manual configuration tasks can be significantly reduced, freeing up time for more strategic work.
7. Greater Flexibility: With NetDevOps, it’s easier to manage and adjust network settings to meet changing needs. This is particularly useful in cloud-based environments, where demand can fluctuate.

In summary, NetDevOps enhances the network lifecycle management by bringing together the best of networking and DevOps. It enables teams to manage networks in a more efficient, reliable, and agile manner.

Network DevOps Tools

This list is not exhaustive, but these are the main DevOps tools you need to know about for networking.

• Git
• GitHub / GitLab
• Ansible
• Python
• Terraform
• Docker
• Jenkins

In the realm of Network DevOps, Continuous Integration (CI) plays a pivotal role in automating the process of integrating changes from different contributors. Leveraging cloud-based platforms, CI tools such as Jenkins and Travis CI allow network configurations and codes to be tested in real-time, ensuring data consistency and integrity across the network.

At the heart of this automation are APIs, which serve as the connective tissue between different software tools. APIs enable interaction between cloud platforms, CI tools, and the network infrastructure, making automation possible at scale.

For network developers, CLI (Command Line Interface) remains a powerful means to interact with network devices. However, IDEs (Integrated Development Environments) like Visual Studio Code or PyCharm offer an even more comprehensive toolset for writing, testing, and debugging network automation scripts for netdevops engineers.

NetDevOps is not just DevOps!

DevOps is about more than just tooling. It’s about a cultural shift towards more collaboration and shared responsibility for maintaining the network. The automation potential of NetDevOps is fulfilled by using a range of tools, often cloud-based, that facilitate efficient coding, testing, and deployment.

Git plays a key role in this process. As a version control system, Git allows teams to collaboratively develop network automation scripts, track changes, and revert to previous versions if necessary. It is the backbone of many CI/CD pipelines and an essential tool in the NetDevOps toolbox.

In essence, NetDevOps brings together the power of DevOps principles, cloud technology, automation, APIs, CLI, IDEs, and tools like Git to create a flexible, scalable, and reliable network infrastructure.
