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.
