You'll would have to bump up from 128GB ram for a fair comparison. I didn't look exhaustively, but $.02/core-hour is hard to beat, especially since he's quoting that much memory and real (not smt/hyperthreads) core hours.
- justinclift 3y agoOh, good point. Yeah, that'd need to double the ram if they're going to use 4GB ram per SMT core. :) Doing that moves the cost up to €165.80 for 64 SMT cores with 256GB ram for a full month. (Note - I've updated those prices as I previously forgot to set the region to "US" for the Hetzner pricing thing) -- Lets see if my math is working today. ;) €165.80 / 64 cores = 2.5906 per core, per month Using 720 hours a month for our purposes, that's €0.0036 per core hour. -- Use xe.com to do pricing conversion, that €165.80 is US$179.79. So, $179.79 / 64 cores = $2.809 per core, per month Using 720 hours a month for our purposes, that's US$0.0039 per core hour. So, about a fifth of the price of $.02/core-hour.
- tyingq 3y agoThat is comparing an SMT core to an actual core. The c5.18xlarge is 36/72 cores/vcpus. Still cheaper, yes. Though I don't know how much you lose in scheduling trying to keep it fully utilized 24/7 versus the spot pricing.
- justinclift 3y agoOk, I must be confused? You pointed out initially that it's 128GB ram for (only) 32 real cores. That's still 4GB ram per core. What am I misunderstanding? :) -- That being said, if they're just doing bursty work and won't use servers for long stretches then it's probably not the right choice.
