You may have heard by now that Digital Lifeboat offers cloud-based online backup systems. But you’re probably wondering just what is “the cloud” and how is it better than backing up to an external hard drive, for example?

Let's start with how your PC works. You open an application, like Microsoft Word, and you type a letter, and save the content on your hard drive. The application (Word) and the data (your letter) are on your PC. Cloud computing is an approach which involves the creation and deployment of services and applications over the internet, supported by a coordinated infrastructure. When you open your email, the application is “in the cloud” and when you send the email to a friend, the email is stored “in the cloud.” Lots of services like search engines, YouTube, Flickr and Facebook operate this way.

The popular buzzword, “cloud” simply means storing digital files on someone else's computer and accessing it by internet.

What people like about “the cloud” is that they can access content on-demand. What businesses like about “the cloud” is that it shares computing resources (networks and servers), that requires minimal management and effort to both access and release. With cloud computing, it’s easy to partition resources for you to use, and when you’re done using those resources, it’s easy to re-integrate those resources back into the cloud for others to use. Cloud computing is an efficient way to increase network capacity and utilization, without having to go out and purchase more equipment that – in the end – will just contribute to the growing problem of e-waste.

With all the different methods and applications used in cloud computing, it would be more accurately described as “sky computing”, with little grouped clouds for each application or service – one for Facebook, another for Salesforce.com, another for YouTube, etc.
