What's in this template
7 connected components you can rename, recolor, and extend with AI.
An event-driven architecture diagram shows how components communicate asynchronously by publishing and subscribing to events instead of calling each other directly. At the center sits an event broker or streaming platform: producers emit events into it, consumers react to those events, and an event store keeps an immutable log for replay and auditing. This decoupling lets services evolve and scale independently.
Architects, data engineers and backend teams use this diagram to design pub/sub systems, streaming pipelines and reactive microservices. It is especially useful for explaining eventual consistency, fan-out behavior, and how Kafka or a message queue routes events between many producers and consumers without tight coupling.
Great for
- Streaming pipeline design
- Pub/sub system planning
- Microservices decoupling
- Data engineering docs
- Architecture reviews

How to customize this template
- Open it in the canvas with Use this template.
- Put the component every request passes through, such as the gateway, broker or load balancer, in the center node, since every other node connects to it.
- Write the protocol into the label, for example Orders Service (gRPC) or Billing Events (async), so readers can tell calls from events.
- Swap generic icons for real vendor logos with the icon search, so the diagram matches the stack your team actually runs.
- Mark what you do not operate, such as third-party APIs, the CDN or a managed database, by adding (external) or (managed) to its label.
- Export a PNG or SVG for docs and slides, or a GIF or MP4 to keep the animation.
Frequently asked questions
What is event-driven architecture?+
It is a design where components communicate by producing and consuming events through a broker, instead of calling each other directly, which lets services stay loosely coupled.
What are the components of an event-driven architecture?+
Key parts are event producers, an event broker or streaming platform like Kafka, consumers that react to events, an event store for replay, and often a schema registry and stream processor.
What is the difference between events and messages?+
An event is a notification that something happened and may have many subscribers, while a message is often a directed command to a specific consumer. Brokers can carry both.
Why use a dead letter queue?+
A dead letter queue captures events that fail processing so they can be inspected and retried later without blocking or losing the rest of the stream.
