Your active/passive setup is based on something external to nginx deciding
whether the traffic goes to the nginx1 server or the nginx2 server.

Your active/active setup will probably also be based on something external
to nginx deciding whether the traffic goes to the nginx1 server or the
nginx2 server. Probably you will want a load balancer.

Many exist, including nginx: you can have a third server that
reverse-proxies to either of your current servers.
