What is the Cloud?

What is the "cloud?" The cloud is enabled by the internet. Traditionally, software and data are stored on a user’s own desktop, local servers or company servers. Instead, cloud computing enables software as a service (SaaS) -- where resources are stored remotely and delivered them over the internet--on an as-needed, pay-as-you-go basis. Data and services can then be accessed from any computer, irrespective of location or even operating system. All you need is a web connection.

Cloud computing provides a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities. Anything you 'consume' outside the firewall, is in the "cloud".

It’s easy to see why cloud computing - in all its forms - continues to gain momentum. Users can work anywhere and, if your computer breaks or your laptop is stolen, you won’t lose any data. Its scalability means you only pay for the resources you need. The cost and hassle of maintaining lots of computers and software is someone else’s responsibility. And the economies of scale offered by the cloud mean that services can be made available at lower prices.
