The Event Mesh: A Primer

An event is a change, action, or observation in a system that produces a notification. Events are triggered by changes such as master data entity updates like a customer billing address change, or an action like a new order or a trade approval. Other triggers are more basic, like a battery charge level threshold being met or a periodic temperature reading from a sensor. It is common to refer to the notification as the “event.” Rather than use the term trigger, software architects often say “send an event” when a specified condition occurs.
