Very cool tech. But ridiculously expensive. According to [1] you pay $5 per 10,000,000 requests, <10ms each. That works out to less than 27.8 hours of CPU time

And that's assuming near-perfect utilization of that 10ms window and ignoring upfront cost of Pro plan, which this is an add-on to. Compare that to Linode/Hetzner/OVH/etc. where you get half-CPU for that money (i.e. 360 hours CPU time per month). And yeah, sure. Not apples-to-apples. FaaS, infinite scalability, yadda, yadda. But computing http responses is still computing http responses. Is this FaaS magic dust really worth 1400+% premium?

Another reason why this is not an apples-to-apples comparison is that most people don't run their VMs at 100% utilization. In fact, I'd wager the vast majority sit at single-digit percentages on average. Linode will still charge you for the full CPU, of course.

  Well, CF always charges you for full 10,000,000 requests/mo too. Also, it is super-common (especially on low end) to offer burstable CPU VMs [1,2]. So you are not getting charged for full CPU, unless you specifically ask for it.

    You aren't paying for Workers for the CPU time IMO, you're paying to be in 155 locations around the world so that your code runs closer to your user. You couldn't split a hetzner/ec2 box across locations like that. A lot can be accomplished in 10ms on Workers in my experience since they don't count waiting on network requests as part of that 10ms. If requests only require <10ms of CPU anyway, $5 per 10 million requests is pretty reasonable to me.
