academia & corporations .
• So the real concept behind cloud computing is “SHARE CPU
TIME”.
• 1960-1990’s- John McCarthy opined in 1960’s that

Major models of cloud computing
service

16.
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.

SD Card Micro SD Card
 Allows your content to become mobile
 Save to the storage device
 Take device to any compatible computer
 Open and use content

23.
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

24.
When you do a “save as” on your computer, you choose where to save the material.

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.
Other Software services
