When publishers are saddled with inventory they can’t sell to advertisers, they often turn to ad exchanges, where advertisers bid for online ad space. Real-time bidding for online ad impressions occurs in milliseconds. For this reason, Ad Tech companies, which are essentially brokers for the advertisers and the web publishers, need to be able to write applications that can execute on extremely large data sets in near real time. With low-read latency during high-write rates and increased throughput, Aerospike is the winning bid for the best price/performance ratio and cost-effective scaling.
