Keeping a cool head in the clouds

Following commentary on cloud computing and related topics such as data security in the cloud is a fairly thankless activity, given the amount of unsubstantiated views and commentary from non-practioners. But I recently turned up one sober, cool-headed analysis of the relevance of cloud computing in different scenarios; the article highlighted areas in which cloud would work fine, and those in which it would be entirely the wrong architecture to adopt.  As this blog claims to offer a reality check approach to our industry, it makes sense to offer the link for you here.
