What is cloud computing?
 

Cloud computing, otherwise called as cloud storage, is a new technology for data storage over the internet. It is a hybrid technology of computing services like software, servers, networking, databases and analytics and its storage and many more over the internet. In simple words, we can put ‘cloud computing’ as the delivery of computing services to servers, data storage, databases, networking, software, analytics and much more through the internet, ie, ‘the cloud’ in other words. Companies which offer these sort of computing services are known as cloud providers, and they charge for cloud computing services based on the client’s usage / consumption, like how we are getting billed for the usage of water or electricity at home. These cloud services get delivered on-demand through the internet on a pay-as-you-go pricing basis.

 
Why is it called a cloud?
 
Cloud is a data storage model in which the digital data is stored in logical pools. The physical storage spans multiple servers and often multiple locations. And this physical environment is typically owned and managed by a hosting company, eg a public cloud administrator, like Amazon. These cloud storage providers are responsible for keeping the data available and accessible and running them in a protected environment. Individuals and companies either buy or lease the storage capacity from the providers to store their user / organisation / application data or all together.

 

What is the need for cloud computing?
 

Cloud computing allows individuals / companies to use its applications for storing data without installation and access their data thus stored through any device viz mobile, laptop, tablet or desktop connected with internet.

 
Where exactly is this cloud?
 

It is somewhere at the other end of the internet connection where we store our files and can be accessed from anywhere in the world, which is a big deal primarily because of three reasons:

  1. we need not have to maintain or administer any infrastructure for that matter
  2. since it is virtually infinite, a cloud will never run out of storage capacity
  3. we can access our cloud-based data or applications from anywhere across the globe with a device that gets connected through the internet.
