Netezza Corporation (NYSE: NZ), the global leader in data warehouse and analytic appliances, today announced that AppNexus is using the Netezza data warehouse appliance to power its innovative real-time ad buying platform. By choosing Netezza, AppNexus was able to get to market quickly with a 92 percent reduction in operating costs. With rapid analytics enabled by Netezza, AppNexus advertisers can run an intensive data analysis for every ad impression purchased in real-time, which leads to dramatic increases in advertising performance metrics. 

The Netezza-powered AppNexus real-time ad buying platform facilitates transactions between aggregators of publisher ad inventory and leading buyers of online advertising. Ads are placed based on up-to-the-moment information about what ad content, placement and timing generates the highest response and revenue. After installing the Netezza data appliance, AppNexus was able to rapidly go from processing 1.5 million requests each day to more than 400 million requests per day. The Netezza system is scalable to serve tens of billions of advertising impressions per month for AppNexus, at a rate of 30,000 per second.

Netezza's data appliance is a key factor in AppNexus's success. Watched as one of the most respected up-and-coming companies in the demand-side platform (DSP) market, AppNexus was founded by Brian O'Kelley and Mike Nolet, the technical team behind the world's first and most successful ad exchange, Right Media, which sold to Yahoo! in 2007 for $850 million.
