Broker Tour: Google Cloud Pub/Sub

Pub/Sub has topics and subscriptions. Subscribers must ack; otherwise Pub/Sub redelivers. It aims to avoid delivering the same message to multiple subscribers of the same subscription simultaneously, and deletes acknowledged messages asynchronously.

Use cases: global fan-out, event ingestion, push/pull subs in managed form.
