- aspyct 6y agoWhich, all things considered, seems lower on the cloud. Could you give more details on this answer?

- HatchedLake721 6y agoDropbox has outgrown AWS. I’m not sure it’s a good example.
- lazylizard 6y agoA 2u asus with 2 xeon silver, 64gb ram and 4 x 2080ti is maybe us$15k? We'll use it for as long as its producing useful output. Lets say 5 years? Probably a little longer? A 60bay 4u western digital with 14tb drives is under us$50k? definitely got a dell md1280+1u server with 70x10tb 2yrs ago for under us$50k. Fully populated the following year.. A 2u dell with maybe 20 cores n 128gb ram each should cost less than us$10k. And we just got 4 or 5 dell switches with 48x10g ports for 50-70k? I'm not sure. What's the equivalent in the cloud?
- aspyct 6y agoAre you keeping tabs on the cost of the building and associated security? Video cameras, locks... Also the manpower needed to install and maintain that equipment. Similarly, your 70*10tb tells nothing. What's the redundancy on that, how much of that space did you lose to it, where do you store your backups and at what cost? As for networking, having those switches is nice, but you still need your internet connection if you're serving anything online from this.
- lazylizard 6y agoThe manpower to run that stuff is already doing desktop support. Storage is usually a stripe of 10 disks in raidz2 + 2 spares. Then we do a nightly zfs send.. The internet connection for the hosting is 100mbps. The users share 1gbps of internet. We pay only for hardware. Rent and utilities. And the internet connections. Everything else we can do it ourselves. I mean. Seriously. Whats the cost of running 100 x 4 x 2080ti in the cloud for a year? Or storing 500tb(1 instance only,no redundancy) ?
- bluedino 6y agoSo service contracts on any of those?
- lazylizard 6y agoWhat service contracts? Only hardware warranties n extended hardware warranties..

- ThrowawayR2 6y agoAWS EC2 m5d.2xlarge (8 vCPU / 32 GB / 300GB nVME SSD) for a 3 year term is $4,466. That's enough for 3 HP ML10s equivalently configured plus the power to run them for their entire lifetime, which is well over 3 years. You are paying out the nose for the fancy-pants deployment and administrative features that the cloud gives you, and for a lot of use cases, that isn't needed.
- aspyct 6y agoYou're forgetting the human part in this cost. Installing, securing and maintaining the machines costs as well.
- ThrowawayR2 6y agoI'm not; for non-production compute workloads, the cost is negligible. Even for production workloads, the 4x premium over base hardware cost is absurd.
- aspyct 6y agoTotally disagree with that. Humans are expensive. Cabling, configuring, training, ordering and replacing hardware, that all takes time. Over a period of 3 years, there's a high chance that you'll end up having, depending on your luck, at least a few dozen days used up by those tasks. Assuming you're not paying peanuts for your contractors, this will easily get to the $10k or over.
- ThrowawayR2 6y agoIf you disagree, give us your example TCO estimates for all of that vs cloud. I'm sure HN readers would be happy to dissect it.
- aspyct 6y agoUnfortunately I don't have exact numbers, having never been responsible for the budget of those. This is only an estimation considering the pricing I see from the cloud providers, and the rates I know from my fellow contractors. Besides, I'm not exactly trying to win a war here. Simply trying to know under which circumstances it is better to go for on-prem vs public cloud.
- nojito 6y agoDo you have a source on this? By any reasonable metric, onprem is much much cheaper than the cloud.
