Deliver event data wherever you need it

Cloud Pub/Sub is a simple, reliable, scalable foundation for stream analytics and event-driven computing systems. As part of Google Cloud’s stream analytics solution, the service ingests event streams and delivers them to Cloud Dataflow for processing and BigQuery for analysis as a data warehousing solution. Relying on the Cloud Pub/Sub service for delivery of event data frees you to focus on transforming your business and data systems with applications such as:

• Real-time personalization in gaming
• Fast reporting, targeting and optimization in advertising and media
• Processing device data for healthcare, manufacturing, oil and gas, and logistics
• Syndicating market-related data streams for financial services

Build multi-cloud and hybrid applications on open architecture

Syndicate data across projects and applications running on other clouds, or between cloud and on-premises apps. Cloud Pub/Sub easily fits in your existing environment via efficient client libraries for multiple languages, open REST/HTTP and gRPC service APIs, and an open source Apache Kafka connector.

Scale responsively and automatically

Scale to hundreds of millions of messages per second and pay only for the resources you use. There are no partitions or local instances to manage, reducing operational overhead. Data is automatically and intelligently distributed across data centers over our unique, high-speed private network.

Bring reliability and security tools to real-time apps

Use Cloud Pub/Sub to simplify scalable, distributed systems. All published data is synchronously replicated across availability zones to ensure that messages are available to consumers for processing as soon as they are ready. Fine-grained access controls allow for sophisticated cross-team and organizational data sharing. And end-to-end encryption adds security to your pipelines.

Cloud Pub/Sub Features

At-least-once delivery

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

Exactly-once processing

Cloud Dataflow supports reliable, expressive, exactly-once processing of Cloud Pub/Sub streams.

No provisioning, auto-everything

Cloud Pub/Sub does not have shards or partitions. Just set your quota, publish and consume.

Integrated

Take advantage of integrations with multiple services, such as Cloud Storage and GMail update events and Cloud Functions for serverless event-driven computing.

Open

Open APIs and client libraries in seven languages support cross-cloud and hybrid deployments.

Global by default

Publish from anywhere in the world and consume from anywhere, with consistent latency. No replication necessary.

Compliance & security

Cloud Pub/Sub is a HIPAA-compliant service, offering fine-grained access controls and end-to-end encryption.

“Cloud Pub/Sub makes it simple for us to decouple our background data and event processing from the code that handles user-facing requests. This lets us analyze data in real-time with lower code complexity and without impacting the performance of our site.”

- Colin Fuller, Khan Academy

“We are very excited about the productivity benefits offered by Cloud Dataflow and Cloud Pub/Sub. It took half a day to rewrite something that had previously taken over six months to build using Apache Spark.”

- Paul Clarke, Director of Technology, Ocado

“As one of the earliest Google partners to develop a set of reusable tools, reference architectures and methods for accelerating IoT products to market, we’ve been impressed with Cloud Pub/Sub, a durable, low-latency and scalable service for handling many-to-many asynchronous messaging.”

- Agosto
