Guess what? The cloud is not magic โ it's a computer in a box that never sleeps. Today we build one, protect it from NEPA ๐, and put a real webpage on it that your friend's phone can open!
A server is just a computer whose only job is to serve โ when a browser knocks and says "please give me the page!", the server answers "here you go!" A data centre is simply a big cold building with thousands of these, stacked like loaves of bread on bakery shelves.
Thinks super fast and answers every knock: "who wants a page? Here!"
A quick notebook for things it's working on right now. Bigger jotter = more visitors at once!
Where all the piggy banks (folders) and coins (files) are kept safe.
Where the internet cable plugs in โ every visitor enters through this door!
Our school server is a small quiet box (a "mini PC") โ it drinks less power than a light bulb! Tap all 4 parts to bring it to life:
Our mini cloud drinks only ~55 watts โ less than a bulb! So a battery + solar panel can keep it awake all night. Press the naughty button and watch what happens:
Drop your file (your coin ๐ช) into your folder (your piggy bank ๐ท) on the server โ then everyone on the class WiFi can open it! And through a magic tunnel โจ (a free tool called a Cloudflare Tunnel), even Grandma far away can see it at lab.koinder.biz!
Polish your shiny coin โ your index.html!
Into YOUR folder on the server โ your piggy bank on the mini cloud.
Everyone visits your page on their phones โ applause! ๐
"My website lives THERE. That box is a server!"
Copy to the town bank (cloud backup) โ two piggy banks, zero tears!
