I'm a Systems Administrator. I manage the Linux servers and infrastructure that keep my organization running, from provisioning and patching to backups, monitoring, and uptime. It's the kind of work I always wanted but was never trusted with early in my career. Now the server room is my responsibility rather than somewhere I'm locked out of. Every day I'm doing the work I used to watch other people do, and I genuinely enjoy the depth of it.
I started in desktop support, handling every workstation issue in the building. I was good at it, and I knew the users and their machines inside out, but the servers always stayed under someone else's control. I felt stuck at the very edge of the real infrastructure, close enough to see it but never allowed to touch it. I knew I wanted to manage systems, not just endpoints. That growing frustration is ultimately what pushed me to retrain and aim higher.
I was drawn to the systems side because that's where the important decisions actually happen. Desktop support is mostly reactive, fixing whatever breaks in front of you, but administration is about designing and maintaining the backbone everything else depends on. I wanted ownership and real depth rather than a stream of one-off tickets. The challenge of running infrastructure genuinely excited me. I knew that if I could build the right skills, it would be far more rewarding work.
CertLabz let me practice on real systems instead of just reading about them. I built servers, configured services, and broke things safely in the labs until the work started to feel natural. The performance-based questions put me in realistic scenarios that mirrored the job, and SkillTracker kept me focused on my actual weak spots instead of wasting time. It turned abstract knowledge into hands-on competence I could rely on. By the end I trusted my own skills completely.
"The step-by-step labs filled every gap I had. I went in unsure and came out running the servers."
Alyssa Waldron, Systems AdministratorI came out genuinely comfortable on the command line and confident managing real servers. These are the exact skills I use every single day now, not just theory I memorized for an exam.
Earning my RHCSA was the real turning point. It proved I could administer Linux systems to a recognized professional standard, and it finally gave employers a concrete reason to take me seriously. Within months of certifying I was promoted into a systems administrator role. That credential opened the door I'd been knocking on for years. It changed how people saw me almost overnight.
What I valued most was how practical everything felt. Nothing was abstract for the sake of it; every lab and question connected directly to the work I'd actually be doing. That made the learning stick in a way that reading never had for me. I also appreciated being able to see my own progress clearly, which kept me motivated through the harder topics. It made a big career change feel manageable.
Stop waiting to be handed the keys and go build the skills yourself. Practice on real systems, because that hands-on work is what makes the knowledge stick and what actually gets you hired. Pick a respected credential like RHCSA that proves real ability, and let your practical work back it up. The infrastructure side of IT is closer than you think. If I could cross that gap, so can you.
Next, I'm deepening my automation skills with tools like Ansible and looking at managing larger, more complex environments. I'd like to grow from administering systems to designing them, so I'm exploring cloud infrastructure and infrastructure-as-code on the side. Longer term, my goal is to lead an infrastructure team of my own. CertLabz gave me the habit of learning by doing, and I've kept that momentum going ever since. Every new skill I build seems to open another door, and I'm genuinely excited to see where it takes me.
