Could easily use this for web scraping. But at amazon prices? Ha!

Amazon gives some examples though "With up to 100 Gbps of network bandwidth, your simulations, in-memory caches, data lakes, and other communication-intensive applications will run better than ever"

Ingres is free though.

Yes but they've recently added some P2W features, which is a bit concerning. Here's hoping that they tone down the IAPs in the coming months, before they retire the old scanner.

You seem like the ideal customer.

Large parallel computation jobs such as machine learning model training that require massive amounts of data would benefit from instances like this.

Clustered processing, where info is being sharing among your machines as the processing is happening. Anything you imagine running simultaneously on racks of machines will benefit immensely from faster interconnects between each machine on the rack.

Molecular dynamics simulations

are latency, not bandwidth-bound.

I performed MD simulations all throughout my PhD, on three different supercomputers as well as on a virtual cluster I set up on Azure. I didn’t say latency wasn’t a bottleneck; but the parent poster asked why additional bandwidth would be needed. It’s definitely necessary, but not sufficient.

I would argue though that for simulations with very long-range force fields or ones that include quantum chemical effects, bandwidth is THE bottleneck. Latency more so for short range force fields for non-reactive potentials.
