Two essential tasks of event streaming platforms are reliably storing and fast processing of streams of events. These platforms must successfully manage high volume of messages (millions per second) and must support all types of event sources (databases, IoT sensors, mobile devices, cloud services, software applications…)
Event streaming helps you get all the information you need, when you need it, providing constant data flow. This enables software architecture and model for application design called event-driven system: all components in a system of this kind are producing messages or reacting to messages in an event streaming platform.
