How Network Administrators Can Transition into DevOps Engineering

Network administrators already have experience managing infrastructure, maintaining connectivity, and troubleshooting technical issues. These skills provide a useful starting point for moving into DevOps engineering, where teams automate infrastructure and streamline software delivery.

TL;DR

• Build on your existing networking and infrastructure knowledge.
• Learn Linux, Python or Bash, Git, and cloud fundamentals.
• Practise CI/CD, containerisation, and Infrastructure as Code.
• Create projects that demonstrate automation and deployment skills.
• Gain workplace experience and prepare for relevant DevOps roles.

Quick Answer

Understand How Network Administration Connects to DevOps

1. Identify Your Transferable Skills

Network administration develops technical knowledge that is useful in DevOps environments. Your existing experience may include:

• Configuring routers, switches, and firewalls.
• Managing DNS, VPNs, and IP addressing.
• Monitoring network performance and availability.
• Troubleshooting connectivity and security issues.

These responsibilities help you understand how infrastructure components communicate. For example, your knowledge of routing and firewall rules can help diagnose connectivity problems between cloud servers and applications.

2. Understand the Shift to DevOps Responsibilities

Traditional network administration focuses on maintaining network devices, managing access, and resolving connectivity issues. DevOps extends beyond these activities to include infrastructure provisioning, application deployment, automated testing, and monitoring.

The main difference is how work gets done. Instead of repeatedly configuring resources manually, DevOps engineers use code and automation tools to create consistent environments. You will also collaborate with developers, testers, and cloud engineers throughout the software delivery process.

Build the Technical Skills Required for DevOps

1. Learn Linux and Scripting

Linux is widely used across cloud servers, application environments, and DevOps tools. Start with these fundamentals:

• Command-line operations and file management.
• File permissions and process management.
• Service administration and package installation.
• System logs and basic troubleshooting.

2. Learn Git and Review Networking Fundamentals

Git helps teams manage changes to source code, scripts, and infrastructure configurations. Learn how to:

• Create and manage repositories.
• Commit changes and work with branches.
• Review modifications and resolve basic conflicts.
• Share projects through GitHub.

Explore Cloud Platforms and DevOps Tools

1. Choose One Cloud Platform

Begin with AWS, Microsoft Azure, or Google Cloud. Learning one platform thoroughly is more useful initially than studying several platforms without practical experience.

Focus on its core services:

• Compute: Virtual machines and computing resources.
• Networking: Virtual networks, subnets, and route tables.
• Security: Identity management and access controls.
• Storage: Cloud storage and resource management.
• Monitoring: Resource usage and service health.

2. Understand CI/CD and Containers

Continuous Integration and Continuous Delivery (CI/CD) automate application building, testing, and deployment. Explore Jenkins or GitHub Actions and learn how a code change can trigger an automated workflow.

Then move on to container technologies:

• Docker: Packages applications and their dependencies into containers.
• Kubernetes: Manages and orchestrates containerised workloads.

Start by building and running a simple Docker container. Once comfortable, explore how container networking works and how Kubernetes manages communication between workloads.

Learn Infrastructure as Code and Network Automation

1. Practise Infrastructure as Code

Infrastructure as Code (IaC) allows engineers to define and manage infrastructure through configuration files. Terraform is a widely used tool for provisioning cloud resources through code.

Start with a small exercise:

1. Install Terraform and configure a test environment.
2. Create a virtual network and subnets.
3. Provision a virtual machine.
4. Review and modify the configuration.
5. Store the files in a Git repository.

This exercise introduces automated infrastructure provisioning and version-controlled configuration management.

2. Automate Network Operations

Use your networking experience to identify tasks that can be automated. Tools such as Netmiko and NAPALM support Python-based automation for compatible network devices, while Ansible helps manage configurations across infrastructure.

Try building a small workflow that:

• Collects device information.
• Checks network connectivity.
• Verifies configuration settings.
• Generates a report of the results.

Test automation scripts in a controlled environment before using them on operational systems.

Build Practical DevOps Projects

1. Create a Cloud Network Automation Project

Use Terraform to provision a basic cloud network containing:

• A virtual network.
• Public and private subnets.
• Routing rules.
• Appropriate security configurations.

Store your configuration files in GitHub and include a simple architecture diagram. Explain how the resources communicate and how the environment can be deployed or updated.

2. Develop a CI/CD Deployment Workflow

Build a small application deployment project using GitHub Actions or Jenkins. Store the source code in Git, configure automated testing, package the application with Docker, and deploy it to a test environment.

Add a basic health check to identify deployment or application failures. Document the pipeline stages, deployment steps, and troubleshooting process so employers can review your implementation.

Prepare Your Resume for DevOps Opportunities

1. Highlight Relevant Experience and Projects

Present your experience through technical responsibilities and actual contributions rather than listing routine duties. Include relevant work involving network troubleshooting, firewall configuration, infrastructure monitoring, and automation.

2. Apply for Suitable Transition Roles

You do not need to move directly into a senior DevOps position. Consider opportunities such as:

• Junior DevOps Engineer.
• Network Automation Engineer.
• Cloud Operations Engineer.
• Infrastructure Automation Engineer.
• Site Reliability Engineering Associate.

Compare job descriptions with your current skills and identify the requirements you still need to meet. Apply when you can demonstrate the essential skills with the right resume instead of waiting until you have mastered every DevOps technology.

Conclusion

Network administrators already possess valuable infrastructure and troubleshooting experience. Build practical projects, seek supervised automation opportunities, and demonstrate your technical abilities through documented work. These steps can help you move towards DevOps and related infrastructure engineering roles.
