AWS EventBridge¶
What it is¶
AWS EventBridge is AWS's serverless event bus service for routing events between AWS services, SaaS applications, and custom applications. It enables event-driven architectures by matching events against rules and routing them to targets (Lambda, SQS, Step Functions, etc.).
Roles in Slack's Shipyard¶
EventBridge serves two distinct roles in Shipyard:
- Image pipeline triggers: When slack-zero finishes baking successfully, EventBridge fires an event → Lambda automatically triggers downstream service image pipelines in service-owner accounts.
- Fleet inventory substrate: Peekaboo consumes EC2 lifecycle events (launch, terminate, state changes) via EventBridge for near-real-time fleet visibility.
