In fact there is probably a growing problem that the ways this could have been solved in Kubernetes is slowly approaching the number of ways that it could have been solved on good ol' baremetal/ec2's. Kubernetes != non-bespoke system.
I like the fact, however, that there do at least exist standard primitives in Kubernetes that could approach horizontal scaling (if that was the issue as is insinuated by the aforementioned laughing) since the best thing Kubernetes does for me is helping me keep my cloud vendor (aws,gcp,azure,etc) knowledge shallow for typical web hosting solutions.
