A year ago, I thought DevOps was just "someone who knows Jenkins and Kubernetes." I was so wrong.
I'd scroll through job postings feeling lost. One wanted a "DevOps ninja," another needed a "cloud wizard who also codes." What does a DevOps Engineer actually do?
Then I found this TestLeaf blog that changed everything. It wasn't another tool checklist—it explained the why behind the role.
The Lightbulb Moment 💡
DevOps Engineers solve flow problems in software delivery. They engineer systems that help teams ship code frequently, safely, and predictably.
It's not about memorizing tools. It's understanding why releases get stuck, how deployments break, and where team silos create bottlenecks.
What They Actually Do
When I explored courses in DevOps, I learned the real responsibilities:
CI/CD Pipelines: Creating automated quality gates, security checks, and rollback strategies—not just running builds.
Infrastructure as Code: Treating servers like software. Versioned, testable, predictable.
Production Reliability: Monitoring, designing for failure, reducing recovery time.
Team Enablement: Removing bottlenecks by standardizing workflows.
Skills That Matter Long-Term
After a course on DevOps, I realized lasting skills aren't specific tools:
Systems thinking—understanding failure cascades
Automation mindset—eliminating repetitive work
Cloud fundamentals—networking, compute, storage
Communication—explaining risk, influencing teams
That last skill? Career-defining, yet rarely discussed.
Why Testers Should Care
DevOps for testers is exploding. Modern QA isn't just test cases—it's shifting left, automating in pipelines. If you're in testing and ignoring DevOps, you're missing a huge opportunity.
My Takeaway
DevOps isn't a checklist role. Tools change yearly, but principles like reliability and automation stick.
Before any course on DevOps, understand you're learning how to make software delivery efficient. That skill compounds across your career.
