How is the cloud less secure than your on-prem servers? I would argue that it's easier to keep track of all the threats with the tools available from big cloud providers.
The cloud provider has physical access to the machines. They may have software access to the machines. I'm sure they're contracted not to do anything bad, but there is risk of an insider incident at the cloud provider leading to an incident the customer can't prevent.
Mostly, headspace. If I run my own server, I just need to apply my existing Ubuntu sysadmin knowledge. If I use AWS, I have to learn a whole load of AWS-specific domain knowledge, starting with their utterly baffling product names. My time is more valuable than that. Also, sheer cost. Literally everyone I know in my particular part of the industry uses Hetzner boxes. For what I do, it’s orders of magnitude cheaper th…
If that's not true, it turns out it's quite expensive to run things in the cloud. If your workload is crunching numbers 24/7 at 100% cpu, it's better to buy the cpu than to rent it.

1. 500TB of storage for 3-6mo of CCTV footage. 2. Bought a hanful of $700 24 core Xeons on eBay 2 years ago for 24/7 data crunching. Equivalent cloud cost was over $3000/mo. On-Prem paid off within a month! 3. Nutanix is nice. Awesome performance for the price and almost no maintenance. Got 300+ VDI desktops and 50+ VMs with 1ms latency.

Which, all things considered, seems lower on the cloud. Could you give more details on this answer?
A 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…
But the real reason we're not deeper in the cloud is that our business-types insist on turn of the century, server-based software from the usual big vendors, and all the things that integrate with them need to use 20th century integration patterns, so for us migrating to the cloud (in stages at least) would have drawbacks from all options without the benefits. It's only where we have cloud-native stuff that we can sneak in under the radar for stand-alone greenfields projects, or convince the business types that they can replace the Oracles and Peoplesofts with cloud-first alternatives will things really change.

Can you clarify? I don't think such a product exists as a single chip at that price point. The Threadripper 3960X costs $1400, and that released less than a year ago.
Edit: Looking up Intel chips on Wikipedia, I think you might be using 12-core/24-thread chips...

> Hundreds of terabytes a day is really not that much How much would it cost to move this across boxes in EC2? I actually don't know, that's not a rhetorical question. A lot of our servers have 10-40gbit links that we saturate for minutes/hours at a time, which I suspect would be expensive without the kind of topology optimization we do in our datacenters. > Also surprised about latency We've spent a surprising amoun…
Seems you’re trying to bring your on-premise structure and concepts to the cloud, that won’t work. EC2 instances are cattle, not pets. I believe I saw a slide that average lifespan of an EC2 instance at Netflix is 14 minutes. I’m not necessarily saying cloud will work for your setup, but you can’t compare like that.
