Hello,

Unless i'm mistaken, you just want to implement several backends or
directors, then you can use server.ip and server.port (
https://www.varnish-cache.org/docs/3.0/reference/vcl.html#varnish-configuration-language)
in VCL to make the requests go to one specific backend (you need to make
Varnish listen on several IP/Ports on the command-line, though).

You can then use your LB or even let the Varnish director of your choice
handle the load-balancing - depending on your needs. If you have a single
IP per cluster, you can use a single backend.
