Cloud computing glossary

Do you speak cloud? Let's start at the beginning. Cloud computing is a general term for anything that involves delivering hosted services over the Internet. Did you know that the name cloud was inspired by the symbol that's used to represent the Internet in flowcharts and diagrams?

A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, it is highly scalable and the service is fully managed by the provider.

Cloud services are broadly divided into three categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). A cloud can be private or public. A public cloud sells services to anyone on the Internet. A private cloud sits behind a firewall and "sells" services over the Internet to corporate customers who are also inside the firewall.
