Lawrence Livermore National Lab's powerful new supercomputer

So with $120m/y in less than 2 years you'd exceed the price of the whole thing and also likely get worse interconnect speed and possibly raw computational speed.

AWS looks like a bad deal here.

If you have a constant load, on premise is always cheaper. Scientific computation has, for a large enough organization, a 100%

If you have a variable load, cloud infrastructure may make sense if you can easily auto-scale.

In my experience, most business real world applications are multi tiered applications with variable loads hence are a good fit for cloud infrastructure.

However, attaining the required application flexibility and KPIs for efficient auto scaling is quite hard and require strong functional & technical expertise.

My experience totally reflects this. Most enterprise IT infrastructure is idle the majority of the time.

I'm running infrastructure for a SaaS app in k8s. I feel like I'm doing well sustaining >50% efficiency, i.e. all cores running >50% all the time and more than half the memory consumed for things that aren't page cache. Hard to get better efficiency without creating hot spots.

That's GCP on preemptible nodes and you are correct.

Not a great deal.
