Bah!
The real problem with the personal cloud and indeed the vast majority of IT tech coming down the pipe for the last 10 years is not the technology, it's the willful obfuscation of what a given scenario actually encompasses by use of maddeningly imprecise marketing-friendly "clixby*" terms.
"8X performance vs (insert competitor)" - Does NOT mean "8 times the performance" or there are some horrendous misprints in the metrics on the slide being shown as this is said.
"On demand scaling" - rarely is on demand anything as it requires a negotiation of some sort in order to switch on the resources in question. That negotiation may be entirely electronic but since billing is involved look for unforeseen complications when the resource is actually needed that once in any given year.
"Vertical (anything)" - Better check your vendor's marketing bible before you buy.
"Fault tolerance". "High availability". These are terms that mean specific things to vendors. Unfortunately, the fine print is on a per vendor basis.
So is it any wonder no-one is doin' it rite? If you drive a technology by aggressive marketing you can't be upset when no-one takes it very seriously after a couple of seminars**.
