Apache HTTP Server vs Unicorn: What are the differences?

What is Apache HTTP Server? The most popular web server on the Internet since April 1996. The Apache HTTP Server is a powerful and flexible HTTP/1.1 compliant web server. Originally designed as a replacement for the NCSA HTTP Server, it has grown to be the most popular web server on the Internet.

What is Unicorn? Rack HTTP server for fast clients and Unix. Unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels. Slow clients should only be served by placing a reverse proxy capable of fully buffering both the the request and response in between Unicorn and slow clients.

      We use httpd in front of our Tomcat web server. Apache terminates the TLS connections and forwards to the embedded Tomcat server(s) for request processing. We also use it as load balancer for multi-server deployments.
