The concept of Cloud computing refers to several application and services all over the internet and it is a group of system software and hardware that are totally responsible to offer those services and applications. This combination of hardware and software is known as internet or cloud. Cloud computing is basically a new technology and gaining more and more popularity since last few years. Basically it is virtualization of technology in which several distributed computer systems are tightly connected together to form or make a large virtual computer system which can easily maintain the computation and huge amount of data.
This virtual technology makes it possible that each computer system appear as a separate computation machine allowing users to install operating system and software on each separate physical machine and the user can also configure or set rules for each and every node. The concept of cloud computing is basically evolved from the concept of distributed computing, parallel processing and grid computing. According to a study, the data is no longer available on the one’s personal computer system but are hosted to be accessible at any time in any location.
It is a fact that this whole process is completely attractive and beneficial. It is best opportunity to access all the applications and services more efficiently and effectively. But to keep data secured all the time you will need high security. The new technology in IT generation offer much effective and efficient approach in order to access the It tasks. All cloud based applications and services are delivered through a third party which is a combination of private & public clouds and internal resources.
There is a consensus that this internet technology has many advantages, but the most of the businesses are not totally committed to invest in cloud computing services and applications because of the security, management and proper regulation of the data and resources. According to the 2009 survey, only 59 % of the businesses were familiar with the idea of Cloud Computing.
It is a shared environment for the employees so that they can easily access the several shared resources from any location. All the users seem to be very comfortable with browsing shared resources and document files that are stored in the main cloud machine. This was all about the concept of cloud computing technology. All the characteristics of cloud computing are the necessity of an individual and businesses that are seeking to deduct the cost.
