The 3 Tier Model

One of the most proven and stable Web Infrastructures used over the last few years is the 3 tier model.
This simply comprises of a database tier, a application server tier and a webserver tier.

And for many years this proved quite successful.

One of the best combinations for stability and reliability was:

Oracle Database

Weblogic Server

Apache Webserver

The operating system of choice was normally unix (Sun / HP-UX).

Since Apache and oracle both ran so well on Unix Solaris and the Sun Sparc based Hardware was
to make this a great combination.

Great in such ways as - Uptime was fantastic -- sun boxes almost never need a reboot
Performance - great!

Configuration -- Nightmare!
