Yes. This should not present a problem. Regardless of the location of the machines behind your load balancer you would just specify them by their IP. We have a whole section of tutorials on setting up load balancing solutions. I'd recommend starting there.

  • alright thanks , one more thing ..
    what about the IP addresses of the droplet and the external servers? it should be public or private?

    • When load balancing for servers outside the same DO datacenter you would use only public IPs.

      For any droplets within the same datacenter you could use the private interface.

      • so I set the droplet IP to private and the external servers to public?

        • Sorry, let me clarify. If your load balancer is on a droplet and your other servers are outside DO you would only use public IPs for everything. DO private IPs only allow for communication between two droplets in the same datacenter.

          • alright thanks alot, am going to use the droplet as a load balancer for the external servers so there will be aren't any other configuration in this droplet

          • if the type of os of my external servers is centos 6.6, the type of the image for the droplet will be centos 6.7?

          • Since a load balancer simply routes traffic via HTTP/HTTPS it doesn't matter a lot what distro you use. If you're looking for consistency then, yes, it would make sense to go with the CentOS 6.x image we provide.

  • alright.. thanks alot
