Isn't it funny how Google announces free GKE stuff the day before EKS was announced AND made generally available? :-) Like Jobs issuing a press release that the App Store had hit 3B downloads the morning of the Nexus One launch.
I'd speculate that Google did it on purpose the first time (everyone knew there had to be an announcement coming, and the date of re:Invent was well known in advance.)
Given what some are saying in this thread here today, I would not be the least bit surprised to learn that Google's announcement this time actually forced Amazon's hand, and that the folks on this afternoon's Amazon's twitch stream actually found out yesterday that they'd be making the announcement today.
Yeah, it was safe to assume they would announce something related at re:Invent, given that they had joined the CNCF a few months before, after simply ignoring Kubernetes for years.
I would agree with you, but no one (honestly) knew when EKS was being announced at GA, including customers we talked to. I think this was just a coincidence.
