There is a rapid increase of data streams being generated by applications, devices, the wide web, processes and enterprises which need to be processed, stored and analyzed securely and at scale. There are many technologies to address these event streams, but the key is to recognize that event-driven action is the end goal of these event streams. You can think of event-driven workflows in ERP, CRM and HCM that have event flows, which were traditionally using JMS messaging. Or they could be streaming news, sensor data or social media posts sent to various sets of Apache Kafka subscribers.
