Event Broker

Q: How does an event broker work?

An event broker receives events from producers and distributes them to subscribed consumers based on topics, routing rules, or filtering logic.

Q: Where are event brokers commonly used?

They are frequently used in microservices architectures, IoT platforms, streaming analytics, and systems that need to react to real-time changes.

Q: What platforms provide event broker capabilities?

Common examples include Apache Kafka, Solace, AWS EventBridge, Azure Event Grid, and Google Pub/Sub.

Q: How does CloudQix support event-broker-based designs?

CloudQix can subscribe to brokered events and trigger downstream workflows, ensuring each event updates the right systems, APIs, and data sources automatically.

Part of the CloudQix Glossary of of Integration Terms, this page explains what event broker is and how it supports modern integration and automation workflows.

Definition

An event broker is a system responsible for receiving, routing, and delivering event messages between producers and consumers. It enables event-driven architectures by ensuring events flow reliably across distributed services.

In-Depth Explanation

Event brokers manage the flow of events across decoupled systems, making sure producers and consumers do not need direct knowledge of each other. Applications publish events when something happens, and subscribers react only to the events they care about.

Unlike traditional request/response integrations, event brokers push updates when changes occur, which improves speed, scalability, and responsiveness. They can route events to many consumers at once, filter streams, or transform messages as they pass through.

Event brokers are commonly used in microservices, IoT, analytics, and real-time automation where low latency and high throughput are critical. They help organizations react quickly to business or system events.

CloudQix integrates with event brokers by subscribing to event streams and triggering automated workflows, ensuring that each new event can drive synchronized updates across connected systems.

Examples by Industry

Finance: Banks use event brokers to broadcast fraud alerts, transaction events, and regulatory notifications to multiple downstream systems.
Software: Engineering teams rely on event brokers to connect microservices that react to user actions, system health signals, or configuration changes.
Retail: Retailers publish events for new orders, inventory changes, and fulfillment updates so multiple applications stay in sync.
Transportation & Logistics: Logistics providers stream location updates, dispatch changes, and delivery events through event brokers for real-time visibility.

Why It Matters

Event brokers matter because they power real-time, event-driven architectures that can react quickly to changes. They reduce coupling between systems, improve scalability, and enable flexible routing patterns that support modern digital operations.
