Google Cloud Pub/Sub
Global, real-time messaging for applications and data integration.
Overview
Pub/Sub is an asynchronous and scalable messaging service that decouples services producing messages from services processing those messages. It allows services to communicate asynchronously, with latencies on the order of 100 milliseconds, and is used for streaming analytics and data integration pipelines.
✨ Key Features
- Global availability and scalability
- At-least-once delivery
- Push and pull message delivery
- Message filtering
- Schema enforcement
- Dead-letter topics
🎯 Key Differentiators
- Global by default, simplifying cross-region architectures
- Combines queuing and fan-out (pub/sub) capabilities in one service
- Tight integration with Google's data analytics and serverless platforms
Unique Value: Provides a simple, globally scalable, and fully managed messaging service that enables reliable, asynchronous communication between applications.
🎯 Use Cases (4)
✅ Best For
- As an event source for Argo Events, triggering workflows when messages are published to a Pub/Sub topic.
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Applications requiring strict message ordering across all messages (Kafka partitions offer stronger ordering guarantees).
🏆 Alternatives
Its global nature and combined queue/pub-sub model can simplify architectures that would require multiple services (like AWS SQS + SNS) in other clouds.
