‘The cloud’ is just computers in giant data centers that you reach over the internet. This animated explainer shows where your photos really live, why it’s called a cloud, how over 99% of data between continents travels through cables on the ocean floor, and the trade-offs of trusting someone else’s computer.
Someone else’s computer
‘The cloud’ means computers you reach over the internet. Your files sit on someone else’s machines. You can open them from your phone, laptop or TV. Lose your phone, and the copy in the cloud stays.
Inside a data center
Cloud data lives in data centers. They hold rows and rows of computers called servers. Your data is stored and processed there. Then it’s sent back to whatever device you’re using.
Why call it a cloud?
Network diagrams drew the internet as a cloud. It meant: ‘stuff out there, details not shown.’. The name stuck for services you reach online. But the cloud is real hardware, just out of sight.
The cloud is under the sea
To cross oceans, data mostly travels by cable. Fiber-optic lines lie on the ocean floor. They carry over 99% of data between continents. Satellites carry only a tiny share.
Handy, with trade-offs
Pro: reach it anywhere; it survives a lost phone. Con: you need internet to get to it. You’re trusting a company with a copy of your stuff. Use a strong password and two-step sign-in.
Bonus: You already use it
Web email, photo backup and streaming all run on it. Sign in on a new phone and your stuff comes back. That’s the cloud doing its job quietly.
