Their point (in my interpretation) is with bare metal you can get more capacity than you need, for cheaper. With some cloudflare-ing you could quite easily get away with a single origin server in Germany, too. The latency from a rails app is probably higher anyway. My anecdata with hetzner - 1.5 decades of lightly used servers for hobby project. One power supply failure resolved in a day. They have some quirks, but. If you truly have to scale out, sure, cloud is great (sort of). But you can engineer your solution to take the benefit of both, you win.
