Cloud computing is a concept surrounded in myth and confusion. Various businesses and their marketing departments continue to try and define ‘cloud‘ but become all the more confusing even to an informed customer.

Cloud computing is the use of computing resources – hardware and software – that are provided as a service over a network, typically the Internet.

The name comes from the use of a cloud-shaped symbol as a metaphor used in the system diagrams. Now, there is no need to send e-mails to yourself from home, or burn CDs to give to a friend, or run around with USB sticks or pen drives in your pockets! Cloud computing can revolutionize all these things.

By uploading documents into the cloud, the documents can be accessed anytime, anywhere and shared with others. Rather than having to store music playlists on an MP3 player, they can now be accessed via a phone to keep us entertained on long journeys without taking up space. We can also relax knowing that if something were to happen to our PC it would not matter as everything is stored in the sky – ‘cloud’.

It is a subscription service whereby you access the services of a cloud storage provider over the Internet and have to pay for it to the service provider. It is almost instantaneous. Unlike software which has to be customised to suit your needs, purchased, delivered, installed, and users trained, cloud computing can be accessed the same day as purchase, the user interface downloaded and the backup completed!

Indeed, as technologies grow around us, this is a simpler, more cost effective and a far better means of cloud storage than software options. They say it is the future, when compared to software, you can see why!

So, as per the Wikipedia, Cloud computing is the on-demand availability of computer system computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user.
