I read that one of the benefits of cloud co开发者_开发百科mputing is "Shared Resources" . "With cloud computing, this allows companies all to have access to the resources via cloud computing". But what is different between the time when companies make a web site and put all their resources on it and add a log in option for making it secure and the time when put their data in cloud ? Can any one explain it for me please?

I suppose you mean, what's the difference between having a web application with a companies data on it, like a school intranet website, and a system of storing data on a particular set of servers and allowing access to those servers from remote locations? In that case, I guess there is no difference, except the medium through which you access the data - one is just through a wb browser connecting to the data.

I am not too sure I got the question correctly. To me you have misunderstood the meaning of "shared resources". In the context of cloud computing, shared resource is usually a peace of

• hardware
• software
• infrastructure

Shared resources mean that same software or equipment can be used by many companies (but not at the same time). Given you have low demand, you can reduce your company's bill by consuming less cloud resources - you return them to the cloud. Once the demand is high, you can dynamically request more resources from the cloud.

one major thing with the cloud is that its hosted. so you never have to worry about hardware. as for data access you can do anything u could on your own server. also the cloud can auto expand size and bandwidth limitlessly.
