Believe it or not, pretty much every cloud that runs full stack apps has a similar proxy / service discovery layer. Even if they only let you run in one region.

Believe it or not, pretty much every cloud that runs full stack apps has a similar proxy / service discovery layer. Even if they only let you run in one region. If you run your app on your own servers with your own load balancers and terminate your own TLS, you avoid a lot of this infrastructure. If you use anyone with a "cloud" load balancer, you get almost exactly what we've described here. Complexity is a legitimate reason to manage your own server. A single server with a single database and nothing between you and the users avoids a lot of complexity.
