If so, I would play with it to see how it fits our needs.
LVS has several advantages over nginx, the principal one being that it *isn't* a webserver. It's a load-balancing framework, pure and simple. Whether you want web, mail, DB, SSH, some_other_app is irrelevant - it can probably be done. It isn't a proxy, it's an application-agnostic router with features allowing several different types of load balancing algorithm, method, and scheduling. > [Is it correct that LVS provides failover semantics as well?
