Are these terms exactly synonymous? As I understand them, they all denote large facilities housing arrays of servers for compute. Are there any nuanced differences in meaning, in the sense that, for instance, a storage-intense facility that hosts videos for streaming would be called something other than a processing-intense facility for LLMs or crypto mining? Would these services even be housed in the same building or apart? ---

Subtle differences. A data centre is the whole shebang. A server farm is what goes in the building to do the work. Usually. A hosting centre could just be the building. Also a building where you rent space to place your servers. Or it is the business model - we provide the hardware, you rent time on the hardware to do your business. The critical part of the rent time on compute model is that you can be a small startup, and if you suddenly need more server capacity you can just rent more in the same facility. The classic business failure of not being able to cope with success can be sidestepped. Providing this model is what made Amazon the huge player it is. Nobody builds their own server systems except for the very very big, or the very small. Which is why everything is in the cloud. (As the pithy aphorism goes - A cloud computer is just someone else’s computer.) ---

You can use them however you wish. The terms have drifted far afield of their original meanings anyway. “Data center” evolved from “data processing center” which was the part of a business office where the mainframes were situated. Then as telcos came to rely more and more on data processing and computer equipment, they initially stored their computerized switches in the “wire center” which was the hub for telecom lines, and then as the data management outgrew the resources of the wire center, new sites called “carrier hotels” or “telco hotels” were fitted to house just the electronic equipment, the computers and switches. This was the genesis of the highly-networked computing facility that we now call a “data center” which I think emerged in the 1980’s or perhaps even the 70’s. It should be noted that a server farm doesn’t necessarily need to be located in a data center. If it doesn’t need a lot of connectivity or special cooling and power needs, it can be just a floor or room in your building. ---

> [@Francis\_Vaughan](#): > > A hosting centre could just be the building. Also a building where you rent space to place your servers. During the dot-com boom, I worked for a company that rented space in data centers to place our servers. As I understand it, the initial business model was that we paid per square foot of space used. But then as the servers grew more dense, they started to charge based on the amount of power we were using. ---

Not so much a nuance in terminology (it’s all fuzzy, as people have pointed out), but sometimes they can differ by use case. A streaming video provider, for example, doesn’t want just one mega-big data center. It’s better to have many smaller ones scattered across the world, closer to their users, each with a fast connection to local ISPs and cell phone carriers. Same goes for web hosts. These can be purpose-built data centers, or rented space (from a few servers to a few buildings) within someone else’s data center. For crypto it’s a bit different, since there’s not necessarily need for blazing-fast internet. In those cases they can be located wherever power is cheap, like shipping containers at oil wells in the middle of nowhere, with only a basic connection to the internet. Most of the processing happens locally, on the servers themselves. For AI, it’s like crypto on steroids. It needs very fast local compute and networking (within/between servers) and a LOT of available power. The data centers have to be very well-equipped with processors and memory and very big and very well-cooled and very frequently upgraded and able to draw a lot of power. AI compute needs make even crypto seem easy in comparison, and it’s what’s driving the current explosion in data centers. > [@Dewey\_Finn](#): > > But then as the servers grew more dense, they started to charge based on the amount of power we were using. My understanding is this is typical for data center billing and build-outs… individual tenants can install & upgrade hardware to their needs, but the physical facility has to be able to provide (and adequately cool) a certain amount of power & heat. You can always swap in faster chips later, but they still run into the building’s inherent power and cooling limits… revamping those would require an extensive remodel to the facility itself. It’s gotten to the point where power availability (whether existing or new power plants) is the primary barrier to new AI data centers now. They’re giant, hungry machines turning ancient algae into intelligence. Or sunlight into sentences, if you prefer.
