There are two versions of Cloud Run. The fully-managed cloud-only variant is actually an API skin over Google App Engine. The "for Anthos" (née "for GKE") variant is Knative[0] in both API and sourcecode. AWS could plausibly do exactly the same thing: provide a skin over Lambda that speaks Knative. I think Amazon's and Microsoft's reluctance to wade into Knative has been wariness about Google's intentions. And maybe 6 months ago I would have said "fair enough, I would be cautious too". But the recent update to Knative's governance model largely resolves the problem, in my view. I would very much like to see AWS and MS involvement. [0] "Knative" is the correct spelling, FWIW. Disclosure: I work for VMware, which participates in Knative development. I also, like, wrote a book about it.
