Is it possible to use the same instance of HAProxy for multiple services by configuring multiple frontend and backend sections ?
I have a Linux system which has been assigned multiple IP addresses (primary and aliases) on the WAN interface and has HAProxy running on it. Can I use the same instance of HAProxy to load balance multiple services (being serviced by different set of backend servers) by configuring multiple frontend sections, each of them listening on a different IP address ? The proposed configuration would be on the following lines where x.y.z.11 and x.y.z.12 are the IP addresses of the WAN interface. frontend alpha bind x.y.z.11:443 mode tcp default_backend alpha ... ... ... frontend beta bind x.y.z.12:443 mode tcp default_backend beta ... ... ... backend alpha mode tcp server abc 192.168.100.11:443 check server def 192.168.100.12:443 check ... ... ... backend beta mode tcp server mno 192.168.100.21:443 check server xyz 192.168.100.22:443 check ... ... ... If this configuration is not possible, are there any alternative ways of using the same system for load balancing multiple applications listening on different IP addresses and running on different backend servers ? Thanks, Manish
