Data centers run the Internet. Whenever you use Microsoft to challenge your friends on XBOX Live, you’re using a data center. The Wikimedia Foundation has databases in a data center to let you read this book.

Many businesses use a datacenter as their "Cloud" for servers and storage. The datacenter also has "Firewalls" as the first point of entry from an external computer, that allow or deny access to the devices behind them. These firewalls see millions of packets daily and their rules quickly determine access permissions. There are also devices like load balancers and switches in the datacenter that carry the load of all these communication packets. The load balancer site in front of several servers and spreads the load of the work among them.

What idea(s) and/or inventions had to be developed before it could be created?[edit]
