Cloud computing is simply a buzzword used
to repackage grid computing and utility
computing, both of which have existed for
decades.
Cloud computing is Internet-based computing, whereby shared resources, software
and information, are provided to computers and other devices on-demand, like the
electricity grid.
-- Wikipedia
- Reduction of costs - unlike on-site hosting the price of deploying applications in the cloud can be less due to lower hardware costs from more effective use of physical resources.
- Universal access - cloud computing can allow remotely located employees to access applications and work via the internet.
- Up to date software - a cloud provider will also be able to upgrade software keeping in mind feedback from previous software releases.
- Choice of applications - This allows flexibility for cloud users to experiment and choose the best option for their needs. Cloud computing also allows a business to use, access and pay only for what they use, with a fast implementation time
- Flexibility - cloud computing allows users to switch applications easily and rapidly, using the one that suits their needs best. However, migrating data between applications can be an issue.
