Cloud computing provides computing resources and services over the Internet. It allows users to access email, store documents and other files, and utilize software applications without installing them on a local device. Common examples of cloud services include email providers like Gmail and Yahoo Mail. Users pay for only the resources they use, like the amount of storage or bandwidth, rather than having to purchase and maintain their own hardware and software.

2.  Example: Yahoo email or Gmail etc.
 User don’t need a software or a server .
 User would need is just an internet connection
and you can start sending emails.
The server and email management software is
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
information are provided to
computers and other devices
as a utility (like the electricity
grid) over the Internet.
