Event Bridge

A practical example

Example: a single 'lead created' event published by the web form feeds the CRM, the lead-scoring service, and the analytics warehouse at the same time, with no extra wiring for each.

What to evaluate before investing

• Ask about delivery guarantees (at-least-once versus exactly-once) and clarify that exactly-once processing covers internal handling only, not external side effects such as CRM writes, which still need idempotent consumers.
• Check whether the bridge supports filtering, so consumers receive only relevant event types.
• Ask what happens when one consumer fails or slows down, including retries, dead-lettering, and backpressure.

Limitations and tradeoffs

Publish-subscribe decouples systems but hides dependencies: when an event schema changes, every consumer can break at once, so versioning events becomes essential.
