Data Centers

Updated Sept 14, 2020 · 2 min read

What are data centers?

Data centers are dedicated physical spaces (often groups of buildings) that house networks of computer systems for running applications and storing data. Computer systems in data centers often communicate with systems in other data centers, creating a wide network of computer systems.

Businesses, especially those that rely on the cloud, use data centers to back up their systems and increase the availability of their applications by distributing data in data centers that span across many geographic locations. Companies like Amazon, Google, and Microsoft have created their own data centers that other businesses can leverage through their cloud offerings.
