Cloud Computing is a new ruling concept that has become popular in the realm of IT. It is referred to the Internet services, and the data center services of hardware and systems software. The hardware and software data center itself is the Cloud. Distributed computing, parallel processing, and grid computing form the base of Cloud Computing. In this concept, the web servers provide the data and applications through ‘cloud’.
In Cloud Computing, the resources and applications of networks are used and shared without the participation of ownership and management. According to Scale, with the help of Cloud Computing, the data is hosted somewhere, instead of storing on a single person’s computer so that it can be accessed irrespective of the time and location. The large amount of data and computation is handled through a big logical computer which is a huge connection of several distributed computers.
Cloud Computing is comprised of various IT services such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Hardware as a Service (HaaS), and Software as a Service (SaaS).
The Software as a Service (SaaS) is the broadest market Cloud Computing service. Through this service, the providers allow the customers only the applications usage. Interacting through the user interface, SaaS provides all the functions of traditional application. In other words, these applications are the provision of Web browser and not of any locally-installed application. With SaaS, the worries of IT about application servers, application development, and storage are reduced to a large extent. Google’s Gmail and Apps, Salesforce.com, instant messaging from AOL, Skype, Yahoo, Google, Twitter and VoIP from Vonage are the popular examples of SaaS providers throughout the world.
