ReactX

ReactX is an advertising platform that traffics "adaptive" advertising -- ad units are filled programmatically based on browser capabilities across devices and on the unused white space on a web site. 

Ars Datum was brought in to re-architect their server infrastructure in AWS to increase performance and uptime, while reducing ad delivery latency and costs, all while accommodating their rapid growth and wide variance in platform and bandwidth usage during various ad delivery campaigns.  Ars Datum's architecture allowed the platform to idle at low cost and spin up to deliver terabytes of video advertising within minutes as campaigns required.
