What has surprised me about the cloud is that the price has been towards ever increasing prices for cores. Yet the market direction is the opposite, what used to be a 1/2 or a 1/4 of a box is now 1/256 and its faster and yet the price on the cloud has gone ever up for that core. I think their business plan is to wipe out all the people who used to maintain the on premise machines and then they can continue to charge similar prices for something that is only getting cheaper.

Its hard drive and SSD space prices that stagger me on the cloud. Where one of the server CPUs might only be about 2x the price of buy a CPU for a few years if you buy less in a small system (all be it with less clock speed usually on the cloud) the drive space is at least 10-100x the price of doing it locally. Its got a bit more potential redudency but for that overhead you can repeat that data a lot of times.

As time has gone on the deal of cloud has got worse as the hardware got more cores.
