We moved our cluster into the Hetzner Cloud for Emvi [1]. Yes, they don't offer a managed solution and it took us about two weeks to set up and test the cluster properly. But the cost is less than 1/6 of what gcloud costs us. If you have the resources and knowledge to maintain your own cluster, check it out. They have insanely good pricing (2,96 €/month for the cheapest instance which is faster than Googles $15/month VM).
Here is a very good tutorial on how to set up your own cluster: https://community.hetzner.com/tutorials/install-kubernetes-c...
