Yeah, they obviously put more thought into this than I ever will. Although they offer instances with 40 (v)CPUs so I'd assume they could technically run 800 nan

Yeah, they obviously put more thought into this than I ever will. Although they offer instances with 40 (v)CPUs so I'd assume they could technically run 800 nanos on one of those and efficiently deal with such spikes? Either way, I suspect their reasoning is more economical than technical, in that they know full well that I can afford more than 5$/mo. (which I'm taking to linode for now, but oy vey, AWS, we'll always have Paris)

Right, these are presumably running on boxes with many CPUs each. Whether instances migrate, I don't know; due to NUMA concerns they might be pinning instances to cores. The other issue to consider is correlated spikes: When you aggregate 800 instances, you're probably going to see a pretty clear diurnal cycle. (And quite possibly middle-of-the-night spikes as synchronized cron jobs all kick off, too.)

  Check it out yourself: https://www.linode.com/pricing https://www.linode.com/pricing. As I said, "more than 5$", in this case meaning 10$, which gets me a CPU core and 24GB of ssd storage. It replaced a dedicated server that was 50€/mo. That server had probably 8 to 10 times the power but the vpn solution can scale within two minutes if needed. I was also having suspected hardware trouble with the dedicated server that the provider couldn't diagnose / wouldn't replace. It's an incredibly boring setup that serves about 200 visitors on a normal day, 2000 during a handful of spikes /year. I know I could probably run it from a Casio watch but it generates six-figures of revenue / year so a bit of overkill is justified.

    Could you explain, if possible, how do you get six figures revenue from 200 visitors?
