PlatformEventBus

Custom EventBridge bus. Most services publish to the shared environment bus instead; use PlatformEventBus.fromPlatform(scope) to import it from the SSM contract.

Defaults

• Name from the platform naming, removal policy from the stack
• Optional archive (archive: { retention, eventPattern? }) for replay

Helpers

• grantPutEvents(grantee)
• eventBusMetric(bus, metricName) for custom widgets and alarms

Alarms

alarms.failedInvocations().

Example

const bus = new PlatformEventBus(this, "Domain", { archive: { retention: Duration.days(30) } });
bus.grantPutEvents(handler);
const shared = PlatformEventBus.fromPlatform(this);
