Hulu Relies on Cassandra to Stream Video to More Than 6 Million Subscribers without Interruption

Industry: Digital Media

The massive increase in the usage of multiple devices, particularly mobile, to provide real-time access to content has fueled the growth of video streaming services like Hulu. As the number of devices and subscribers to Hulu’s service increases, so does the volume of user-generated data, which adds enormous stress on an application infrastructure not built to support this level of data load and velocity of scale. Read to find out how Hulu relies on Apache Cassandra to deliver engaging streaming service to more than 6 million subscribers.
