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                Cloud computing
                  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.

                       Risks of using Cloud Computing

                  Some risks of using cloud computing are:
                     Your sensitive data might be at risk from hackers.

                     Some people might face issues like data loss.
                      The user is always dependent on the Internet. So, if the user is unable to connect to the Internet,
                    he/she cannot access their files and data.
