Cloud Computing is a new technology, which is delivered as a service rather than a product in this modern technology driven market. In olden days, people used mainframe computers widely for various reasons. With the changing technologies, the bigger and most expensive computing devises are getting smaller in size and affordable for people. Yes, mainframe computers used to be very big and complex to handle but today, with the increased technology, the personal computer have become smaller and user friendly.
Several definitions can be derived for the term (Cloud Computing by looking at the usage of the technology at various places. Basically, Cloud Computing is another advanced technology, where software, shared resources and information are provided to computers or any other devises on the network. The name cloud computing has come from the flowcharts that were used in various presentations to represent Internet. Cloud computing has become one of the popular technologies in today's world. It is not only about the computers and other devices that are used for computing but also servers that are used to store the data are kept on cloud computing. Cloud computing has become cheaper due to various reasons. The platforms like software-as-a-service are much more affordable to the users.
[...] As the hardware and data storage equipments are located at the service provider's place, the user can use the applications from anywhere in the world. The major requirement for this cloud is internet connection. Example for SaaS is an On-demand ERP Software Application.

[...] Cloud computing is majorly used for data hosting services. Unlike traditional hosting, where the customer used to purchase the server to store the data or host the websites, the cloud computing gives users an opportunity to purchase the space on the virtual server, which is hosted on the remote network. There are no costs of purchasing and maintaining servers because cloud computing technology offers on-demand services. If a customer wants to purchase some space on the server for a limited period, he or she will be charged for the space and for the time it is being used. [...]

Cloud computing has become cheaper due to various reasons. The platforms like software-as-a-service are much more affordable to the users. Cloud computing is also a popular term among people who deal with the servers. They define cloud computing as a network of remote servers hosted on internet to store, process and manage the data rather than on a local server. [...]
