Interesting theories on the EC2/Annapurna situation.

Do GCP, Azure, or any other cloud providers offer 100G networking?

Not to the instance, AFAIK. Google Cloud maxes out at ~20Gbps, and I think Azure does ~40Gbps.

It's really about flows as well, not necessarily total throughput.

AWS Nitro allows 5G/bit per flow. And then maxes out at 25G/bit. I know GCP does something similar.

Also, pretty sure that is false regarding Azure, they have a small availability of Infiniband, but, that is not on their general compute platform and has a narrow use case/many restrictions. Azure has had the worst networking performance from my experience and only had 10GbE NICs (it's been a while though)

Sounds like a marketing blurb but from just a few days ago:

"Azure is breaking the speed barrier in cloud connectivity. ExpressRoute Direct provides 100G connectivity for customers with extreme bandwidth needs. This is 10x faster than other clouds."

Can sb confirm that? Have a useful case in mind.

I do not believe ExpressRoute is instance level, so not directly relevant to this discussion.
