What Is Cloud Computing? A Plain-English Explanation?

Cloud computing powers almost everything you use online — but every explanation assumes you already understand it. Not this one.

What did people use before cloud computing?

Before the cloud, companies had to buy physical servers, set them up in their own building, hire people to maintain them, and upgrade the hardware every few years. This was expensive, slow, and inflexible. Cloud computing changed everything — now you can rent exactly as much computing power as you need, spin it up in minutes, and shut it down when you're done.

What does SSH stand for?

SSH stands for Secure Shell. The "shell" refers to a command-line interface — the text-based way of controlling a computer. The "secure" part means everything sent over the connection is encrypted. Before SSH, developers used Telnet, which sent everything including passwords in plain text. SSH was created in 1995 to fix that.

How to use SSH — the basic command?

ssh username@server-ip-address # Example connecting to an AWS server: ssh [email protected] # Connect using a key file (AWS / DigitalOcean style): ssh -i ~/.ssh/my-key.pem [email protected]

What's a bucket?

S3 organizes everything into buckets. A bucket is a top-level container with a unique name across all of AWS globally. Each file inside is called an object, and it has a key (its path/name), data (the file contents), and metadata (info about the file).
