What is the Cloud? // cloudy with a chance of server farms (with LEGO)

Upload it to the cloud. Leave it to the cloud. Dropbox, Drive, iCloud, Adobe Creative Cloud,
Evernote, Google Docs. All of these help consumers and businesses
by being in “the cloud”. But forget the fluff, let’s condense it to
what it really means when we reference “cloud”. First let’s reframe the image of a cloud in
your head right now. Sure, for example this is an emoji of a heart. But a heart actually looks like this. This is the imagery people use when they refer
to the cloud, but a cloud actually looks like this. A huge hunk of metal. This is called a server. Which in simple terms is just a giant hard
drive. Ok I’m glad we cleared that up. Now in short we all understand what the “cloud”
means for consumers – like you. This is an easy one. Rather than store photos, videos and other
documents on your computer or your phone, you can store them online. This way they are accessible wherever you
are, on any device, so long as you have an internet connection. We forget that for businesses and startups
the cloud has actually been revolutionary. In the early days of the internet if you had
a website, you would buy a server/supercomputer to put your website on the internet (we’ll
talk about it in another episode). But if you got more traffic, you would have
to go out and buy more servers so it was powerful enough to take all of your new web traffic
you were getting. This was called Hosting. The problem with this, is that not everyone
knew how to maintain a whole server. And you also have to know how to fix it when
something goes wrong. And if you didn’t have backup servers then
you could lose your entire website. As time went on, companies like Google, Amazon
began to offer these “hosting” services for you. This is when the cloud makes a big impact. Rather than needing to buy, maintain, fix,
and secure your own server – a big company like Google or Amazon would do it for you. And then they would ensure that your data
is stored, that it is secured, that it is maintained, that it is running for you. Rather than buy a whole server from amazon,
eventually you were able to pay as you go. Kind of like electricity in your home. If you get a lot of traffic, you pay for that
server usage. If the traffic goes down then you pay less. This is why the cloud is so important. It’s not just so you can store your photos
on icloud. It’s so that businesses can offer services
for you, and focus on that, instead of focusing on how they are gonna service their servers. Here are 5 things to remember about the Cloud. First is that no one is certain where the
term “cloud” came from. The common belief is that the word cloud was
used as a metaphor for the internet in a standardized cloud-like shape that was used to depict the
internet in a computer-network diagram. Two. Different clouds, do different things. Some run data, some store your data, some
run programs. Three. Internet companies have to make huge investments
in the Cloud. Google, Amazon, Facebook. They have to have security backup, cooling
system. Server computers have to be on 24/7, they
produce a lot of heat, they have to be held in cool environments. Four. People still have a lot of hesitation about
putting their stuff on the cloud. Here it is pretty understandable. Take for example the issue a few years ago,
with iCloud, when all these celebrities photos got hacked into, through iCloud. And there were a lot of nudes out there all
of a sudden. Remember that these clouds actually live on
the ground, all over the world. Do you have your own website? Do you have a favourite website? Take that website URL, and paste it into this
link that I’ve provided. (I’ve linked it down below). You’ll see where that cloud lives. Check out where your favourite site or website
lives. Where does your cloud live? Tell me in the comments down below.
