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.

Most known webserver. We are using Apache due to his htaccess feature but its just a backedn to proccess PHP. In font of Apache we are using NGINX to server static files
Apache splits static traffic from application traffic, as well as providing a selection of tools to assist in running of the site (rewrites, logging etc).
Primary web server, delivers PHP-rendered pages as well as static HTML content. Ruby CGIs deliver objects to browser-side code using REST/JSON
modproxybalancer provides highly concurrent end-user browser connections, and manages session routing to the application cluster
Rolling deploys are awesome! We use Unicorn to keep downtime to a minimum as we iterate quickly for our clients.
