The same as if the one machine is hacked/trojaned/.... (or evil proprietary tools are installed and/or run as "root" or equivalent). Maybe it's easier in a cloud because there are more points where someone may find a hole to break in. > >> And recently Google describes a beautiful feature about cloud OS that > >> everyone only need a cheap and simple client,never need update your > >> hardware endless and will get the good services of GOOGLE, online > >> office, online storage,and online everything.... As long as you have really nothing to hide, feel free to use it. It gets interesting if people store data there where someone else thinks that it's illegal. Or details of your company and what you do (in detail) and who your customers are (which may be very interesting to competitors). Maybe that sounds a little paranoid but just think about it *before* you to something. Later it's perhaps too late (as you may remove your account and data there but who knows what *really* happens at the other end). > > And you pay for it with the data you upload and allowing the cloud to > > record every action you so. Oops: s/ so\./ do./ > yeah, i pay for it with the data i upload,but who can guarantee the > data i download from server is as the same as i upload. So i just The one who runs the cloud will guarantee you that (otherwise you probably won't use it, won't you?). And either you can check it (vie whatever means) or you trust it without any (real) check (read: you believe them). > doubt about google's center control services mode. Why are you actually uploading stuff (or even use) in the first place that if you doubt that Google's employees can run that thing? And for a remotely serious analysis of (security) risks, one should know more about the network topology, OS, tools, organizational details, etc. - all involved hard- and software and some wetware-related details (and not only a few buzzwords from some flyer). > >> BUT if one of google servers might crash or be hacked... nightmare > > .. or if Google (or whoever owns it at some future day) just uses Your > > data for whatever the choose to.

Not I find it that uninteresting but "cloud computing" is too much of a buzzword today (or at most a set of incompatible, proprietary "products") to get any real technical knowledge out of it. And the Linux kernel has exactly what to do with "cloud computing". Just the fact that someone may run a cloud on Linux boxes? Just that Google works on a "cloud product" and uses Linux (at least somewhere else)?
