Amazon Web Services/Rubber Band Computing
Having played around for a bit, it's a nice toy for the propeller heads but there's no way I'd trust AWS with my business online computing requirements.
And to be honest the server I was 'playing' with was quietly racking up $60 dollars a month not doing very much. I think I'd rather spend a bit more and host my site with a more conventional provider.
Whilst the work done in this area by Amazon is interesting and good on them if it helps their own business processes tick over, but lets face it they're a retailer not a service company.
Paris...because she enjoys a good 'botting now and again.
