Forrester names Google a Leader in The Forrester Wave™: Streaming Analytics, Q3 2019

High availability made simple

Synchronous, cross-zone message replication and per-message receipt tracking ensures reliable delivery at any scale.

No-planning, auto-everything

Auto-scaling and auto-provisioning with no partitions eliminates planning and ensures workloads are production ready from day one.

Advanced features, built in

Filtering, dead-letter delivery, and exponential backoff without sacrificing scale help simplify your applications

Key features

Stream analytics and connectors

Native Dataflow integration enables reliable, expressive, exactly-once processing and integration of event streams in Java, Python, and SQL.

In-order delivery at scale

Optional per-key ordering (beta) simplifies stateful application logic without sacrificing horizontal scale—no partitions required.

Cost-optimized ingestion with Pub/Sub Lite

Complimenting Pub/Sub, Pub/Sub Lite (beta) aims to be the lowest cost option for high-volume event ingestion. Pub/Sub Lite is zonal and puts you in control of capacity management. View all features What is Pub/Sub?

Use cases

Use case Stream analytics Google’s stream analytics makes data more organized, useful, and accessible from the instant it’s generated. Built on Pub/Sub along with Dataflow and BigQuery, our streaming solution provisions the resources you need to ingest, process, and analyze fluctuating volumes of real-time data for real-time business insights. This abstracted provisioning reduces complexity and makes stream analytics accessible to both data analysts and data engineers.

Use case Asynchronous microservices integration Pub/Sub works as a messaging middleware for traditional service integration or a simple communication medium for modern microservices. Push subscriptions deliver events to serverless webhooks on Cloud Functions, App Engine, Cloud Run, or custom environments on Google Kubernetes EngineorCompute Engine. Low-latency pull delivery is available when exposing webhooks is not an option or for efficient handling of higher throughput streams.
