Memory pricing for all shared/VPS hosting is simply bizarre.
Not really. DIMM modules are fairly cheap but DIMM slots are not. Your average mid-range server can, in theory, be maxed out to 192G or even 256G RAM. But only if you use 8G or even 16G DIMMs - and those are still hideously expensive.
The most cost efficient configuration usually gravitates around 64G (16x 4G) nowadays, rarely higher.
So, when you factor in the cost overhead per server (rackspace, power/cooling, network infrastructure, maintenance) then it's not hard to understand why RAM is the most expensive ressource in the cloud.
