I feel like if you’re maxing one of these clusters for an entire month at a time, it might still be cheaper to just buy one.

- manigandham 6y agoThat's true for any cloud server.
- 867-5309 6y agountrue Intel Xeon Gold 5120 14Core @ £1200 used renting 1Core @ £1.20/mo. would take 6 years to fully pay for that single core alone, and that's excluding the 512MB RAM, 10GB SSD and unlimited 400Mb/s bandwidth
- sbierwagen 6y agoHere's a completed ebay auction from April 20th that sold a 5120 for $699: https://www.ebay.com/itm/Intel-Xeon-Gold-5120-SR3GD-14-Core-2-20GHz-10-40GT-s-UPI-19-25MB-LGA3647-U159103/313059429725?hash=item48e3cbcd5d:g:gCoAAOSwni1ejMs1 https://www.ebay.com/itm/Intel-Xeon-Gold-5120-SR3GD-14-Core-... I know the pound hasn't been doing well lately, but surely it hasn't been that bad.
- 867-5309 6y agowe're still talking years, not one month
- shadowpho 6y agoWhere are you getting $1.20/mo on 1 core/512MB ram/10GB ssd and half a GB bandiwdth? Amazon for example was something like $50/mo for bandwidth alone
- 867-5309 6y agoit's not AWS-grade, just a budget VPS, but has been just as reliable and performant so far. it's out there should you care to seek. the correct currency of £ will help
- reitzensteinm 6y agoYou are renting an overprovisioned timeslice, not a dedicated core. Even Hetzner's time slice instances are twice the price. Their dedicated CPU instances are almost 10x the price.
- 867-5309 6y agopossibly, but nothing to suggest that 6 months in. they suit the use cases perfectly
- reitzensteinm 6y agoIt's definitely a timeslice, and that throws off your comparison wildly. Otherwise you'd be able to rent a 32 core dedicated machine at the same place for $48 a month. Can you?
- 867-5309 6y agoit mentions "dedicated resources", but it's unclear whether this applies to CPU it might throw the comparison off if there was variation in performance at different times, but there isn't cores scale with RAM, you cannot rent 32 with 512MB
- reitzensteinm 6y agoThey're probably talking about dedicated RAM, although even then I wouldn't trust it not to be overprovisioned up to 2:1 on NVME swap. Hetzner dedicated cores come with 4gb of memory per vCPU for reference. 1.2 GBP/mo for a dedicated core is wildly off market price. There's no way they'd be able to make a profit, so either they're going out of business tomorrow or it's not dedicated.
- m3kw9 6y agoYou forgot there is a lot of IT work after buying the hardware to set it up properly. That’s time spent
- nojito 6y agoThat’s a one time cost plus maintenance. Still comes out cheaper than cloud offerings.
- jeffbee 6y agoThe DGX A100 costs a quarter million dollars, so the crossover time might be significantly longer than a month.
- selectodude 6y agoSo six months? Nine months? And at the end, you have an asset. You can always sell it and replace it with the newer model.
- dekhn 6y agoAh, but when you use a large cloud, you're not just paying for the cost of the server. You're paying for access to a large high performance network and storage system that is extremely close to your server. Replicating those properties will cost you far more (well, it depends on your specific needs) than the cloud provider.
- cardine 6y agoWe did the math and decided to buy. For us, the break even point (including everything) was nine months of running 24/7.
