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.

- 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.
Why cloud computing…???

Types of Clouds

• Public Cloud: The services are delivered to the client via the Internet from a third party service provider.Example: Amazon

It is a combination of services provided by the Private and public cloud
Example: –ERP in private cloud –Sales & Email in public

• Private Cloud: These services are managed and provided within the organization. There are less restriction on network bandwidth, fewer security exposures and other legal requirements compared to the public Cloud.Example: HP Data Centers
