"We noticed DataStax was, of course, on top of Cassandra. I wanted to do the benchmark using Cassandra or DynamoDB. That started the story. We saw that for our volume of traffic, DynamoDB was more convenient for lower traffic, but for the volume of traffic we are aiming to, Cassandra was much more convenient. So after a certain point, the DataStax solution was not only more effective in terms of performance, but also cheaper in terms of cost."

The Opportunity

An American mass media company with more than 164 million consumers across 19 brands, including WiredVogueGQ, and Vanity Fair, Condé Nast saw a chance to improve audience engagement using the vast array of user behavior flowing into its databases.

To learn how to better engage its customers, Condé Nast launched a multivariate testing initiative with the goal of fully understanding its user base and the types of content, web layouts, and visual displays that appeal to each target segment.

Condé Nast also wanted to leverage the data gathered in its multivariate testing initiative to provide personalized content and recommendations to web visitors, which they hoped would translate to a more engaging experience and increased online subscribers.
