NewsForge, the Linux and open source newspaper, has a story about the technical underpinnings of eHarmony.
Choice tidbits from Mark Douglas, vice president of engineering and operations:
eHarmony.com chooses open source software for its quality, not for its price.
11 million registered users
Down time on our site costs over $1,000 per minute
eHarmony uses Hyperic’s HQ server management product to keep tabs on 140 servers in its data center.
eHarmony’s Web sites run on open source Tomcat, JBoss, and Apache.
New builds of the site twice a week.
Uses Oracle as a database.
I have previously written about the infrastructure Under The Hood at Match.
