Systems Administrator → DevOps Engineer
DevOps is about shipping changes safely and often. As a sysadmin you know what breaks in production; DevOps asks you to prevent it with automation, pipelines and shared ownership with developers.
What you already bring
- Running production systems
- Scripting and automation
- Change and incident management
- Linux or Windows administration
Certifications that help
- HashiCorp Terraform Associate
- Certified Kubernetes Administrator (CKA)
- AWS DevOps Engineer Professional or Microsoft DevOps Engineer Expert (later)
Certifications open doors; stories of using the skill get you through them. Check each vendor's site for the current exam.
Skills to build
Git and code review
Everything is code: version it, review it, roll it back.
CI/CD pipelines
GitHub Actions, GitLab CI or Azure DevOps: build, test and deploy automatically.
Containers and Kubernetes
Docker images, then Kubernetes fundamentals: deployments, services, scaling.
Infrastructure as code and configuration
Terraform plus Ansible or similar.
Observability
Metrics, logs and traces, and alerts that mean something.
A programming language
Python or Go to write real tools, not just scripts.
A realistic timeline
Put your scripts in Git and automate one deployment with a pipeline.
Containerize an app and run it on Kubernetes in a lab.
Own a pipeline at work and collect stories of faster, safer releases.
Every path is different. These ranges assume steady practice alongside a full-time job.
Interview questions to practice
- A deployment just broke production. What do you do in the next 15 minutes?
- How would you design a pipeline for a small web app?
- What's the difference between a container and a virtual machine?
