How Apcera uses NGINX

• NGINX routes incoming HTTP/TCP requests to the appropriate component

• NGINX also terminates SSL connections• Apcera built an upstream plugin to dynamically reconfigure the routing

and load-balancing as new applications and instances go up and down.• Apcera uses NATS for the configuration messages.

• All messages are signed and encrypted. • The nginx-nats module is open source, https://github.com/nats-io/nginx-nats

• We love NGINX!
