Doing the Sums
I've got a strong hunch that moving the half dozen or so low traffic websites I currently host on a £20/month Linode to either Amazon or Google's cloud offerings would save me money. But the pricing structures are so complicated I don't know where to start with 'doing the sums'.
Reminds me of the mobile phone tariffs of a few years back [or the electricity tariffs of today].
...and then of course there's the uncertainty as to what will happen to these cloud service prices once the big three finish their battle to see who's going to dominate the market. Especially given that common consensus seems to be that it's a war of attrition and they're all running at a loss at the minute, hoping the other guy blinks first.
