 ## Service endpoints
 
-The gatepway acts as a facade for other CS3 services. As such it has to forward requests to a lot of services and needs to establish connections by looking up the IP address using the service registry. Instead of using the service registry each endpoint can also be configured to use the grpc `dns://` or `kubernetes://` URLs, which might be useful when running in kubernetes.

 For a local single node deployment you might want to use `unix:` sockets as shown below. Using unix sockets will reduce the amount of service lookups and omit the TCP stack. For now, this is experimental and the services do not delete the socket on shutdown. PRs welcome.
