                  Cloud Computing







                  Could 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 organisations 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.com  and
                  Google.

                  All the social networking sites such as Facebook, LinkedIn, Myspace, Twitter, Netflix, Skype, and
                  WhatsApp use cloud computing. In fact, all your personal data, photographs, and other details
                  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.

                  Benefits of using Cloud Computing

                  Some benefits of cloud computing are:

                      Cost effective: eliminates the capital cost of maintaining computing infrastructure.

                      Speed and flexibility: allows faster access of resources from anywhere across the globe.
                      Ease  of  storage:  it  offers  unlimited  storage  space  relieving  the  user  from  the  worries  of
                     running  out  of  data  storage  space.  Users  do  not  have  to  worry about  backups.  It  allows

                     co-workers to easily share files and communicate with each other.

                      Data Security: cloud offers advanced security and reliability features to the user for their
                     data. There are many authentication, access control and encryption measures which do not
                     allow unauthorised access to sensitive data.
