My guess is that most cloud customers use fairly little compute and low average bandwidth. But everyone wants "dedicated" cores so this makes a ton of sense and Amazon is raking in billions due to stupidity. Remember the recent story how a couple clicks cut the company cloud bill by a shit-ton. That's probably the norm.
- pants2 3y agoEver since the Spectre/Meltdown attacks came out, it became a big liability not to do dedicated cores.
- jacquesm 3y agoAnd with the crappy scheduling your typical OS provides and containerization as the virtualization mechanism of choice it makes good sense to assign one or more cores to a container.
- ithkuil 3y agoI wonder if there is a timing attack that can be subjected to if you don't also have dedicated bandwidth to main memory
