The very valid question,
|
|
[isn't it too late....to build a
|
|
data center?](https://twitter.com/Mac_S13/status/1181983378100424710)
|
|
was asked on Twitter and it made our team here in Glarus smile a lot,
|
|
and we decided to write a blog article about this question.
|
|
|
|
## Fiber = the advantage of a data center?
|
|
|
|
According to the tweet, the main strength of a data center is fast
|
|
network connection, or the fiber line that you have. And nowadays,
|
|
everyone has fast fiber, so it follows that data centers are maybe not
|
|
needed anymore.
|
|
|
|
## TL;DR
|
|
|
|
It is not that easy.
|
|
|
|
## How to run a data center in reality
|
|
|
|
Some time ago we wrote about
|
|
[How to run a really green
|
|
data center](https://ungleich.ch/de/cms/ungleich-blog/2019/07/12/how-run-really-green-datacenter/).
|
|
Admittedly, the question was not about running a **green** data
|
|
center, so let's dive a bit more into it.
|
|
|
|
Running a data center like we do at [Data Center
|
|
Light](https://datacenterlight.ch) does indeed require a fiber
|
|
connection. To be precise, actually a couple.
|
|
|
|
## How much fiber is enough fiber?
|
|
|
|
Don't tell anyone, but geeks are working at ungleich. And according to
|
|
geeks, there is never enough fiber. But for real, how much fiber is
|
|
needed? In our case, running a data center at 3 different locations,
|
|
requires a couple of dark fiber lines and a couple of redundant
|
|
upstream connections. Using the rule of thumb, let's say we need at
|
|
least 3 fiber connections:
|
|
|
|
* One for location A
|
|
* One for location B
|
|
* One to connect locations A and B
|
|
|
|
So are three fiber connections enough?
|
|
|
|
## What is actually in a data center?
|
|
|
|
Maybe the real question is, why would you run a data center at all?
|
|
Alright, for the geeks of us, "just because I can" is a reason, but
|
|
let's think about other cases as well. For instance we are running a
|
|
data center, because we our customers asked us to run one (easy, isn't
|
|
it?). So some years ago we started buying hardware like switches,
|
|
servers, SSDs, cables, transceivers, disks, network cards, access
|
|
points and even much, much more cables.
|
|
|
|
And why did we do that? Because we were asked to host virtual machines
|
|
and data for our existing customers. So if you want to run a data
|
|
center, you also need a bit of hardware.
|
|
|
|
And there comes one of the bigger problems: hardware also needs to be
|
|
turned on. And if it is on, it actually consumes energy and you do not
|
|
proper fuses. Not only the ones inside the data center, but also the
|
|
ones going into the building!
|
|
|
|
## So what do you need to run a data center?
|
|
|
|
So to run a data center, you need at least
|
|
|
|
* enough power (best to be 100% renewable here!)
|
|
* enough network capacity
|
|
* enough space
|
|
|
|
These are the three base ingridients for a data center. Then the only
|
|
thing that is left, like for every good menu, is a chef. And in case
|
|
of a data center, the chef is the team running it. The team that is
|
|
available all the time, that fixes the network, replaces the disks and
|
|
servers, etc.
|
|
|
|
## Too late or not too late? To be or not to be?
|
|
|
|
We would like to rephrase the question a bit, because we actually
|
|
think the notion of the question was more: **Does it make sense to
|
|
start a new data center TODAY?**
|
|
So what is the answer to this seemingly easy to answer question? Does
|
|
it make sense or not?
|
|
We want to answer with a crystal clear **yes-and-no** answer.
|
|
|
|
### Yes, build a new data center today
|
|
|
|
We encourage everyone to actually build their own data center. Get
|
|
some IPv6 space to your home, get a bit of equipment. Even get some
|
|
servers. Maybe even some ARM servers to save some energy for a change?
|
|
|
|
Build it, like it, maybe even fail at it. It is a great experience to
|
|
build your own. We strongly believe into decentralisation, so we
|
|
encourage distributing the Internet more to different places.
|
|
|
|
Put all the fun stuff on it. Put your development on it. Don't forget
|
|
to backup your stuff to somewhere else, though.
|
|
|
|
We even invite you to [join our chat](https://chat.ungleich.ch) to ask
|
|
about how to build a data center and we are more than happy to share
|
|
our experiences.
|
|
|
|
### No, don't build a new data center today
|
|
|
|
If you start fresh and you are not with an experienced team and you
|
|
want to offer services to other people, we disrecommend building a
|
|
data center on your own. Taking the responsibility to run things even
|
|
when you are sick, even when you want to go to holidays, even if it is
|
|
3am is not very healthy if you are not a team that works well
|
|
together.
|
|
|
|
If you think that the world is already well off with Amazon and co.,
|
|
it is also not a good idea to build one yourself. You need to be able
|
|
to stay in the business even though you get questions like "But I can
|
|
put everything to Amazon - why does it need you?"
|
|
|
|
|
|
## Does fiber at home make data centers redundant?
|
|
|
|
And to answer the other implicit question asked: we think that fiber
|
|
at home actually enables the use of data centers better. So far if
|
|
your connection was slow, you had to have all your data
|
|
locally. With fiber at home, you can store your data anywhere (you
|
|
probably shouldn't, but that is a topic for a different post) and
|
|
access it quickly.
