As the era of WWW began, the information has crossed its limit. Data became the valuable assets.. As compared to before, more and more computers are connected to the web these days. Not only the computers, the newer devices are also the same powerful as the computers, as all the data are on the web.
As we all know that the web is indefinite, the development of software in PCs are much more reliable than that of deploying the software in web. One has to do is deploy the software in the web server rather than PC, as it needs to be installed in every PC that requires. But the software deployed in web, require is web browser. The browser need not to be powerful but rather it should run some of the small program and do some of the local processing. After performing this stuffs, the cost for upgrading can be reduced and so is the maintenance costs. As we see, the business are approaching to the web-based interactions. Web-based system has made the great revolution. Another stage of the web based system is the evolution of the idea of the web services that has the power to deliver the useful function that are available on the web. The systems can be designed by using these services provided by the companies.
Recently the idea of the ‘Software as a service’ has been developed. This idea supports that the software are not just limited to the computers, it has been approaching to the web rapidly. This idea has been trying to change the software trends that are used recently. This system is called ‘Cloud computing’ i.e. all the necessary data is kept over the web. I guess most of us know about the cloud computing. If we take the example of the web-based mail, it is cloud computing. Where all the data is kept on the server and to access it one requires the internet and a browser or web based application. Here in the world of cloud, user do not buy software, they can change the software via cloud as per requirement at any time. All they have to do is pay for what they use.
All the things that are happening on the web, they are changing the business environment. as long as web was not in use, all the computing were done in the single computer within the company. communication were done locally. But now the software as emerging out from the computers are ruling the web and making possible to communicate anywhere and anytime.
