Azure and Oracle were who I had in mind. I think I recall Google's sales team promising it Real Soon Now (i.e. as soon as a federal agency demanded it). I share your experience regarding public cloud's misunderstanding of HPC applications. It's great for the bioinformatics crowd and such but once you need to run nwchem or cp2k you need an interconnect that works. Now I'm disappointed to see that even if SDR turns out to be a good solution, it's so far AWS-only and deliberately opaque so they can screw with it without telling the customer. All part of the bad pattern we're stuck in, where vendors big enough to offer computing at scale don't understand supercomputing, and supercomputing experts get bought and blended into the background without ever scaling up to competitiveness. Shame HP Cloud got canned before HPE bought Cray.
