+## SSL
+
+How will you handle SSL in your HA environment? There are several different

+
+- Each application node terminates SSL
+- The load balancer(s) terminate SSL and communication is not secure between
+  the load balancer(s) and the application nodes
+- The load balancer(s) terminate SSL and communication is *secure* between the

+
+### Application nodes terminate SSL
+
+Configure your load balancer(s) to pass connections on port 443 as 'TCP' rather
+than 'HTTP(S)' protocol. This will pass the connection to the application nodes
+Nginx service untouched. Nginx will have the SSL certificate and listen on port 443.
+
+See [Nginx HTTPS documentation](https://docs.gitlab.com/omnibus/settings/nginx.html#enable-https)
+for details on managing SSL certificates and configuring Nginx.
+
+### Load Balancer(s) terminate SSL without backend SSL
+
+Configure your load balancer(s) to use the 'HTTP(S)' protocol rather than 'TCP'.
+The load balancer(s) will then be responsible for managing SSL certificates and
+terminating SSL.
+
+Since communication between the load balancer(s) and GitLab will not be secure,
+there is some additional configuration needed. See
+[Nginx Proxied SSL documentation](https://docs.gitlab.com/omnibus/settings/nginx.html#supporting-proxied-ssl)
+for details.
+
+### Load Balancer(s) terminate SSL with backend SSL
+
+Configure your load balancer(s) to use the 'HTTP(S)' protocol rather than 'TCP'.
+The load balancer(s) will be responsible for managing SSL certificates that
+end users will see.
+
+Traffic will also be secure between the load balancer(s) and Nginx in this
+scenario. There is no need to add configuration for proxied SSL since the
+connection will be secure all the way. However, configuration will need to be
+added to GitLab to configure SSL certificates. See
+[Nginx HTTPS documentation](https://docs.gitlab.com/omnibus/settings/nginx.html#enable-https)
