I wonder what kind of agreements they have in place when the servers are EoL'd. Sometimes you can find really great deals on obscure custom designs built for a large client (e.g. HP SE316M1 G6/SE1120). I don't think Amazon runs too many data centers with old hardware, the electricity and cooling costs would not be economical. So what will happen to these supposedly custom chips manufactured for AWS by Intel? Surely their value is too much to just turf them all in a landfill (err, I mean, responsibly recycled of course) when their service life is over. Some of them surely must end up on the refurbished server market...
