“We have to be ready for disaster recovery all the time. It’s great that Cassandra allows for active-active multiple data centers where we can read and write data anywhere.”

Case Study: eBay
Industry: All
eBay is the world’s largest online marketplace, enabling the buying and selling of practically anything. Founded in 1995, eBay connects a diverse and passionate community of individual buyers and sellers, as well as small businesses. Today, eBay serves around 171 million customers with one billion live listings.

One of the keys to eBay’s extraordinary success is its ability to turn the enormous volumes of data it generates into intuitive and intelligent searches and useful insights for its customers. To accommodate eBay’s explosive data growth—its data centers perform billions of reads and writes each day—and the increasing demand to process data at blistering speeds, for billions of live listings, eBay needed a solution that did not have the typical bottlenecks, scalability issues and transactional constraints associated with common relational database approaches. The company also needed to perform rapid analysis on a broad assortment of the structured and unstructured data it captured.
