Google Cloud Pub/Sub is one of 18 APIs that [Events](https://apis.io/providers/events/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Bus, Cloud, Google Cloud, and Managed. The published artifact set on APIs.io includes API documentation and an API reference.

Google Cloud's asynchronous and scalable messaging service that decouples message producers from consumers with typical latencies around 100 ms. Uses per-message leasing (not partitions) for parallel processing. Topics and subscriptions (push and pull), schemas (Avro and Protobuf), ordering keys, dead-letter topics, snapshots, and seek. Pub/Sub Lite offers a cheaper zonal/regional partitioned variant for high-volume workloads.
