High Performance Service Achetecture Survey - Frontend, Cache, and LoadBalancer for Web Services

Concept

We find a solution from reference 1.
nginx (for HTTP compression) -> Varnish cache (for caching) --> HTTP level load balancer (HAProxy, or nginx, or the Varnish built-in) -> webservers.

The Reference 2 says :
HaProxy is the best opensource loadbalancer on the market.
Varnish is the best opensource static file cacher on the market.
Nginx is the best opensource webserver on the market.
