Run live data centers

Data center operations is where a facility earns its uptime. These are the four roles that keep the floor running: technician, NOC operator, critical facilities and network & cabling. What each one does, who it suits, and how to prepare with the method interviewers reward.

Four operations roles

The tracks that run the floor

Each role owns different systems and a different interview focus. Pick the one closest to your background, or explore a few before you commit.

Data Center Technician

Data center technicians do the hands-on work on the floor: racking and stacking servers, running and dressing cables, swapping failed hardware, and acting as remote hands for teams that can't be on site.

Explore this path

NOC Operator

NOC (Network Operations Center) operators are the eyes of the site. They watch dashboards and alerts, triage what matters, open and drive incidents, and coordinate the right people to respond, often across multiple facilities at once.

Explore this path

Critical Facilities Technician

Critical facilities technicians keep the physical environment running: utility feeds, UPS and batteries, generators, switchgear, and the cooling systems that stop equipment from overheating. When these fail, the whole site is at risk.

Explore this path

Network & Cabling Technician

Network and cabling technicians build and maintain the physical layer: structured copper and fiber, patch panels, cross-connects, and the labeling and documentation that keep thousands of connections traceable.

Explore this path

Starting any of these tracks with no data center credential yet? The free Data Center Certified Associate (DCCA) is a common first one on entry-level CVs: what its coursework and exam involve. Comparing beyond operations? All 13 roles.

Building or commissioning instead? See the Build path and the Engineer path.
