Microsoft jobs at a glance: Datacenter Critical Environment Technician

The role of a Critical Environment Technician

One of the most common datacenter roles in our operations team, is a Critical Environment Technician (CET). These experts oversee a datacenter’s critical infrastructure—cooling, power, security, and more—to ensure all equipment stays online all the time. Their responsibilities include equipment setup, security, emergency response, and documentation. Working alongside IT teams, they play a vital role in maintaining the critical infrastructure that keeps our datacenters up and running.

What is a datacenter?

A datacenter is a building that houses thousands of computer servers and data storage devices connected to the internet.

Datacenters are the engine that powers cloud computing. Whenever you open an app on your phone, join a virtual classroom or meeting, snap and save photos, or play a game with your friends online, you are using a datacenter. Microsoft’s online services like Bing, Office 365, Xbox, OneDrive, and Azure rely upon datacenters.

The Microsoft cloud infrastructure is made up of hundreds of datacenters and 1 million servers used by 1 billion customers and 20 million businesses in over 90 countries worldwide.
