Cloud computing is a technology in which data, software and hardware applications are accessed from a cloud of online resources. This technology comes in public, private and hybrid forms. Private cloud is not available to everyone who is using the Internet. The Virtual Private Network (VPN) services are provided by the companies, only to those who subscribe to them and who are connected to their network. Whereas, public cloud is available to all who access Internet. This type of computing is provided by companies such as Google, IBM, Zoho, etc. Virtualization, which is a prototype that distinguishes the computing technologies from the physical software, is a key pillar of this technology.

Can This Technology Help in Business Improvement?
Let's say you have a company and a website for your organization. In few years, the number of users of your website increases. You are successful, but with success, problems can come. Your equipment can't keep up with the demand and your service automatically slows down, which ultimately puts you into trouble. What could be the reason behind this? A few years ago, you would have put your website on computer and bought servers to set them up. Hundreds of companies do this, which costs them a lot of money and consumes a lot of time too. This is called 'hosting'. You pay for these servers when you are using them, and you pay for them when you are not using them! By buying these servers, you hope for success in your business, but instead, you lose your customers and end up without any profit in your business. Is there any solution for this? Connect your computer to a cloud server and see what happens. You just have to pay for what you use and manage the demand by varying your utilization of the cloud resources. This lets customers, enterprises and businesses, to use the application services without any requirement for software and hardware installation.
