“Nobody understands the cloud” – Jason Segel, Sex Tape
Give me three hundred words, and you will.
Start by looking at your computer. You can reach out and touch it. You might be able to access this computer remotely, but it’s always one computer. When the computer is running at maximum capacity it will slow down and may stop working. If your computer can’t handle the workload you have to go and get a better one.
Many offices overcome this by having a “server”. A server is a bigger computer sitting in another room in the building. You can walk into the room and see this server. The server has more power than one single computer. Lots of people access the server at the same time and you may be able to access this from outside the building. When the server is running at maximum capacity it will slow down and may stop working. If the servers can’t handle the workload you have to go and get more or replace them with better ones.
Many businesses don’t have their own servers. Their servers are sitting in someone else’s building. If you’re allowed, you can visit this building and see your servers. You should be able to access these servers from anywhere. When the servers sitting in someone else’s building are running at maximum capacity they will slow down and may stop working. If the hosted server can’t handle the workload you have to pay for someone to go and get better ones.
The servers are sitting in someone else’s buildings. You don’t know which servers are being used by you and it doesn’t matter. When the servers look like they are potentially approaching capacity they will be start using space on other servers. It doesn’t matter how much computer power you need, there is always more capacity and you only pay for what you use.
