"Data center" covers facilities that have almost nothing in common except the name.

The building that stores your bank records and the building that trains an AI model are both called data centers. They differ in size, in power draw, in how many people work there, and in what they need from the place they are built. This page explains the differences to help bring clarity to the kinds of projects being proposed in West Viginia

What a data center does

Placeholder. in plain language: racks of computers, network connections, power supply, and cooling, why cooling is the constraint that shapes everything else, including siting.

Placeholder. basic vocabulary a reader will encounter elsewhere — megawatt, load, capacity factor, PUE.

The main kinds, and what each is for

Enterprise data centers

Typical scale: [range] megawatts

Placeholder. A company running its own servers for its own operations. scale, staffing, and typical siting.

Colocation facilities

Typical scale: [range] megawatts

Placeholder. Rented space and power for many tenants' equipment.

Hyperscale cloud facilities

Typical scale: [range] megawatts

Placeholder. The facilities behind cloud services — storage, streaming, business software. This is the category most people picture when they think of "the internet."

Edge facilities

Typical scale: [range] megawatts

Placeholder. Small, distributed, sited for proximity rather than power.

AI training and inference campuses

Typical scale: [range] megawatts

Placeholder. why these facilities are different in kind and not only in size: higher power density per rack, a different load profile, uses (everyday compute vs ai training, surveillance, automation, etc..
