Comment Plan 1: Don't use "The Clouds!" (Score 1) 150
Seriously, unless there is a very real business need ( and no, the CIO jumping up and down about TEH CLOUDS is not a legitimate business need ), keep your data under your control. Not only does this alleviate the problem of bailout should your provider die on short notice, but it also solves the security of cloud data rather nicely.
Granted, that someone even has to point this out shows just how deep the marketing bullshit is on this.
