Scenario A - pointing to an interface as the next hop

Host A configuration (eth0 - 192.168.1.191):

# Remote Address is the IP of Host B eth0

sudo ip link set geneve0 up
sudo ip addr add 10.200.1.1/32 dev geneve0

Nginx TLS SNI routing, based on subdomain pattern

Nginx can be configured to route to a backend, based on the server's domain name, which is included in the SSL/TLS handshake (Server Name Indication, SNI).
This works for http upstream servers, but also for other protocols, that can be secured with TLS.

prerequisites

• at least nginx 1.15.9 to use variables in ssl_certificate and ssl_certificate_key.

The information below was written in Oct 2017. In August 2019 AWS launched official support for multiple target groups per AWS ECS service. Please use that feature instead!
