Data Center
ELI5 — The Vibe Check
A data center is a giant warehouse full of servers, cooling systems, and power backup. When you 'put something in the cloud,' it's literally sitting on physical hardware in one of these buildings. They're temperature-controlled, physically secured, and have multiple power sources so they never go down.
Real Talk
A data center is a facility housing computing infrastructure — servers, networking equipment, storage systems — with redundant power, cooling, and physical security. Cloud providers own hundreds of data centers worldwide, organized into regions and availability zones.
