All my projects are on the company intranet where I work.
LDAP
Phone directory
Real Server
Custom Data mining
Data warehousing
The team is me and one other senior developer, and one junior developer and one gopher. My Boss is the idea guy and the interface to sales / marketing / engineering.
We do everything on:
Linux
Apache
PHP
Postgresql
OpenLDAP
RealServer (the new one, helix server)
On a pair of boxes.
Storage requirements run into the hundreds of gigabytes, and mostly the data sits on the NAS machines in the background.
Our Postgresql database is only about 1 Gig of data when backed up, and runs on local store for speed and reliability.
right now we're trying to get Squid going so we can present many machines (mainframe, legacy boxes etc...) on the web without actually having to expose them.
