The document discusses cloud computing, which involves delivering computing resources as an online utility over the internet rather than through direct usage of hardware and software. Some key points made include: - Cloud computing allows users to access email, storage, databases and other services without needing their own servers or software through services like Gmail, Dropbox, etc. - It provides resources on an as-needed basis similar to utilities like electricity via three common models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). - Benefits include reduced costs, unlimited storage, accessibility from any device, and less maintenance compared to owning physical servers 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.
