$1.20/hr @ 34 GB, $2.40/hr @ 68 GB

Very expensive, unless you only need to use it during peak traffic hours. A month runs you over 700$, and I'm renting a dual quad core with 32GB of RAM, plus bandwidth for 450$ right now.

Where from if you don't mind me asking?

If your load has predictable peaks it may make a lot of sense to spin up 1 quadruple extra large server rather than the equivalent number of large instances, particularly if you're talking about something like a memcached server.

Can anyone explain the odd size choices? I've never done any cloud stuff, or even much local virtualization, but I would have expected sized on the low side or equal to an even number (32gb, 64gb) rather than a little higher.

A maxed out Gainestown server has 72GB of RAM (due to the triple-channel memory controller) and after subtracting Xen overhead you get these numbers.

For Amazon to offer it as an option, they must've got a lot of requests for it. I wonder are machines this scary that common?

How are they scary? I had a pair of 64gb quad hexacores in my last role...

I'm curious about how they provide this much memory, will this memory all be on one machine, or does Xen provide a way to somehow give a VM access to memory on multiple physical machines.

Yeah, the whole 34/68GB is all on a single beefy server. There are systems that let you access remote node's memory in a NUMA type system over fast interconnects, but they're _very_ expensive and have horrible latency.
