Cloud Computing
Cloud computing is a way of storing, assessing, and saving your work online, instead of saving it on
your computer or your smartphone. You can think of it as a hard disk over the Internet. The users
can access files and applications anytime and from any device with an active Internet connection.
Cloud service includes database, networking, software, storage, and servers over the Internet
in a seamless way. Individuals and companies can rent or buy cloud storage from a Cloud
service provider instead of owning and maintaining the complete computing infrastructure.
This saves them the operating costs and problems associated with maintaining their own
infrastructure.
The idea of cloud computing was introduced by the scientist John McCarthy. He introduced
the term timesharing which would enable the organizations to share a mainframe
computer. But the term “Cloud Computing” was coined by Prof. Ramnath Chellapa in the
year 1997. In 1999, the first cloud computing services websites were launched-Salesforce.

that you share on these websites are saved on the Cloud! Google Drive, Amazon Web Service,
Dropbox, OneDrive, etc are some examples of cloud backup services, where you can save and
keep your data secure. Alexa and Google Assistant are natural language cloud-based bots. A bot
is a software program that can do repetitive tasks over
the internet. Examples are chatbots, social bots,
Googlebot, etc.
