Disclosure: I work on Google Cloud. I'll try to translate this into something direct. Anthos is an umbrella term for things in the combined ecosystem of Kubernetes, Istio, Anthos Config Management, Traffic Director, and so on. Anthos [GKE] on {GCP, AWS, Azure, On-prem} is intended to be a consistent version of this deployed thing in each place. There is an important historical wrinkle where traditional GKE already exists, but was "just Kubernetes" and sometimes "with Istio Add-on". I do not agree with the lack of public pricing. tl;dr: For most people here this is GKE "but wherever you want" (this announcement is "on AWS"), including Istio and friends.
