A post after almost a year. But finally I have something new to post.
Linux Virtual Server is commonly employed for load balancing between multiple servers. The load balancer and real servers share a common IP address called virtual IP.
There are three methods for using LVS – Direct Routing, NAT and Tunnelling. The first two methods require direct link between your machines and you should be able to control the routers. There’s no such restriction in the tunnelling method – the servers can be even spread over WAN many kilometres apart.
