Info Hub: 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.
                 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.
