Prompt Title: event-driven application

Here is a high-level architecture diagram for an event-driven application:

                      |Event Broker(s)|

                              | Events

                  |Event Consumer(s) /      |
                  |Stream Processing Engine |
                  |  (e.g. Apache Flink)    |
                  +-----------+------------+
                              | Results / Output
                              |
                              |
                  +-----------v------------+
                  |     Database / Storage  |
                  | (e.g. MongoDB, S3, etc.)|
                  +------------------------+

In this architecture, events are produced by various sources such as webhooks or sensors, and then fed into an event broker such as Apache Kafka. Event consumers, which could be stream processing engines like Apache Flink, consume events from the event broker and process them in real-time. The processed results are then output to a database or storage system such as MongoDB or Amazon S3.

This architecture allows for a scalable and decoupled approach to building applications, where components can be added or removed without disrupting the overall flow of data. The event-driven approach also allows for real-time processing and quick response times, which can be particularly useful in scenarios where data is constantly changing or requires immediate action.
