Edit: they also just added managed databases, though Postgres is still coming soon. Anyone try this?
Their performance is excellent and we've had good experience with them for internal service hosting for some time now. Never put prod on them except for a Discus forum and a few other things like that.
I only use K8s for complicated deployments where cost is something to optimize for. K8s provides vender neutral expression , but once you buy into managed K8s you have a non agnostic management set. managed K8s generally is more expensive and often prevents use of spot.
