•Cloud Computing involves a large number of computers connected through a real – time communication network • 1950’s- Underlying Concept of Cloud Computing dates back to 1959 when large scale mainframe computer available in academia & corporations .• So the real concept behind cloud computing is “SHARE CPU TIME”.• 1960-1990’s- John McCarthy opined in 1960’s that “computation may some day be organized as a public utility”.

Cloud Computing companies have customers of three kinds –
• Infrastructure-as-a-service: Option of renting and utilizing computing power and storage capacity of vendor's quality.
• Software-as-a-Service (SaaS): Vendors license particular services to subscribers on-demand and once the contract expires, the services are disabled.
*Platform-as-a-Service: Here a developer is given the opportunity to utilize various web-tools to build and host applications.

Multiple work stations talk to one unit that stores information and data.
Data is not saved to the C: drive, but to a network drive
Can retrieve the data stored to the network from any of the connected workstations.
Networked Storage

Drawback’s:-Cloud Computing also has some drawbacks like, • The over-dependence on the providers. • The reliability of the vendors. • Protection laws in different countries vary. For eg, according to EU data protection regulation, personal information cannot be transferred outside the European Economic Area. • Threat of unauthorized access to confidential data. • Requires internet throughout and near-impossible to work with dial-up connections.

Can be less expensive compared to buying software and hardware
Can be used from any computer or device with an Internet connection
The device does not need as large of an internal storage system
Compatible with most computers and operating systems
Updates occur across the service
