Is there any benefit of Anthos over deploying straight to GKE if you're already bought into GCP? We've had this debate several times recently and can't come up with a good answer.
If you are bought in to GCP and plan to stay there, then maybe not much. OTOH, Anthos would allow you to do easier migrations from on-prem, support hybrid workloads, or consolidate multi-cloud clusters including those running on say, AWS [1] if you like.
