nginx needs some way of knowing which backend server to use, for each
individual request.

The simplest is probably just to use the host in the request:

==
  server {
    server_name market.cloud.com;
    location / {
      proxy_pass http://market.cloud.com;
    }
  }
  server {
    server_name panel.cloud.com;
    location / {
      proxy_pass http://panel.cloud.com;
    }
  }
==

If that is not appropriate, then the next most straightforward is probably
to change the backend servers so that all of the content on 10.1.0.12 is
available below "/panel/", and all of the content on 10.1.0.16 is below
"/market/" (or some other unique prefix) and use *that* as the way that
nginx can decide which backend to use.
