Ask HN: Is your company sticking to on-premise servers? Why?

The more I learn, the more I believe cloud is the only competitive solution today, even for sensitive industries like banking or medical.

I honestly fail to see any good reason not to use the cloud anymore, at least for business. Cost-wise, security-wise, whatever-wise.

What's a good reason to stick to on-prem today for new projects? To be clear, this is not some troll question. I'm curious: am I missing something?

Simply, _cost_

Our compute servers crunch numbers and data at > 80% util.

Our servers are optimized for the work we have.

They run 24/7 picking jobs from queue. Cloud burst is often irrelevant here.

They deal with Terabytes or even Petabytes of moving data. I’d cry paying for bandwidth costs if charged €/GB.

Sysadmin(yours truly) would be needed even if it were to be run in the cloud.

We run our machines beyond 4 years if they are still good at purpose.

We control the infra and data. So, a little more peace and self-reliance.

No surprise bills because some bot pounded on a S3 dataset.

Our heavy users are connected to the machines at a single hop :-) No need to go across WAN for work.

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?
