Sometimes it seems like the IT industry was the inventor of the acronym, with a new one getting created every two minutes.  Enter Cloud Computing and a host of new and fun abbreviations that can get confused or switched around.

Adron Hall offers a simple run-down (and introduction for some) on three important acronyms in Cloud Computing that are used to represent three general areas in the Cloud:

Software as a Service (SaaS): Perhaps the most commonly heard and understood of the three, SaaS is a service that is provided by any sort of entity – from a small group up to a government – that provides software to the client.  That software could be delivered in any way; internally or from a provider/vendor entity to a user/contracting entity.

Platform as a Service (PaaS): Somewhat less heard-of is the concept of delivering a platform wherein clients can develop software and re-deploy it either internally, over the Internet or via other Cloud environments.

Infrastructure as a Service (IaaS): This entails an entity providing networking fundamentals such as load balancing, routing, virtualized OS hosting, content delivery networks, computer networking, backup, etc.
