Eventbridge

EventBridge is AWS's serverless event bus that connects your applications through events instead of direct API calls. You'll reach for this when building event-driven architectures, whether that's reacting to S3 uploads, routing custom application events between services, or triggering Lambda functions on a schedule. The skill covers the essential patterns: creating custom event buses, writing event pattern matching rules, publishing events with proper structure, and wiring up targets. One thing worth knowing is that rules can have up to 5 targets, which makes fan-out straightforward. The scheduler section is helpful for both cron-style recurring tasks and one-time future events. The event design guidance about keeping payloads under 256KB and using correlation IDs will save you debugging time later.

Core Concepts

Event Bus

Channel that receives events. Types:

Default: Receives AWS service events
Custom: Your application events
Partner: SaaS application events

Rules

Match incoming events and route to targets. Each rule can have up to 5 targets.

Event Patterns

JSON patterns that define which events match a rule.

Targets

AWS services that receive matched events (Lambda, SQS, SNS, Step Functions, etc.).

Scheduler

Schedule one-time or recurring events to invoke targets.

Common Patterns

Create Custom Event Bus and Rule

AWS CLI:

# Create custom event bus
aws events create-event-bus --name my-app-events
