User don’t need a software or a server .
User would need is just an internet connection

all on the cloud (internet) and is totally managed
by the cloud service providers.
The analogy is, ‘If you only need milk, would you
buy a cow?
User need to send email (milk) why should a
user buy a Software / Hardware? (cow)
3. Cloud computing is the
delivery of computing as a
service rather than a product.
Software, Hardware and

computers and other devices
as a utility (like the electricity
grid) over the Internet.
