Cloud Computing
Cloud computing is the use of remote servers on the internet to store,manage and process
data.The cloud computing eliminates the need to store everything on your own computer
hard drive.It allows the user to access pictures,music,files and programs from any device
via the internet.It also makes it easier to collaborate and communicate with others.Major
corporations like Microsoft, Amazon,Google,IBM,Cisco,Dell,HP,Intel and Oracle have
invested in cloud computing.They offer a range of cloud-based solutions for individuals
and businesses.

on innovation and product development instead of managing the resources.It cuts down the
administrative tasks for organization to maintain large amounts of computer hardware and
software.

travels over the internet and is stored at remote servers.It is handed over to a third party.In
addition,the cloud providers serve multiple customers at the same time.It may result in
accidental or intentional security breaches.
Another important concern with the cloud computing is the access issue.The user can access
files programsonly through the Internet.It is not possible to access the data if there is any
