Edge Proxies do regional routing and Routing Proxies route to hosts and load-balance within a region With Regions, the target region determines which fleet of builders we’ll use and which fleet of compute nodes we’ll elect for your deployment. We’re toying with ideas for SNI proxying and support for PROXY protocols to allow you to run your own edge on Railway — and spoiler alert — once we do that, we’ll shift our own L7 proxies to be built atop those L4 proxies we’re giving you.
