Google Container Engine for instance is amazing. Granted Amazon has recently launched a couple of products that offer similar features, but as of mid last year running containers on Google felt like it was ahead of Amazon.
gke is great, however. if you need to run kubernetes in production, today, i would not even slightly hesitate to yell to the corners of the earth to run gke. it makes me excited for eks!
i would also say that the new c5 instance type w/ ena is extremely nice. if they are unaffected by this, they're probably the fastest cpu-based instances you can get anywhere (admittedly i haven't checked... really anything else, but they're fast).
Yeah, the underlying system is optimized for throughput (though we're working on small file latency). AWS clearly has a small file optimization and caching that we don't (yet).
I often point people at Zach Bjornson's blogpost [1] since he compared all three providers and is a neutral third party.
