I really don´t feel K8S have won this battle. I agree people talk more about K8S but i have seen a trend in people that are disappointed with K8S and move against Nomad instead. I guess K8S is too messy. It´s like taking a 2015 enterprise vsphere datacenter environment and containerizing it. Too many layers..
But of course, there´s no fully managed Hashicorp offer for all products in GCP or AWS, Azure....
