GCP Pub/Sub Pricing (2026)
Updated Apr 4, 2026GCPServerless
Managed message queue services enable asynchronous communication between distributed application components. They decouple producers from consumers, improving system resilience and enabling event-driven architectures at scale. Pub/Sub delivers global, real-time messaging with automatic scaling and at-least-once delivery guarantees. Starting from $0.0100/hr ($7.30/mo) for Inter-region data delivery from North America to North America.
Key Features
- ✓Guaranteed message delivery with at-least-once or exactly-once semantics
- ✓Dead-letter queues for handling failed messages
- ✓FIFO ordering and message deduplication
- ✓Automatic scaling to handle variable throughput
- ✓Server-side encryption and access control
Common Use Cases
Microservices Communication
Decouple services by passing messages through queues, ensuring reliability even when downstream services are temporarily unavailable.
Task Processing
Distribute background tasks like image processing, email sending, or report generation across worker fleets.
Event-Driven Architecture
Build event-driven systems where components react to messages published to topics or queues.
On-Demand Pricing
Pay-as-you-go pricing with no upfront commitment. You are billed per hour of usage and can start or stop at any time. Hourly rates start at $0.0100/hr ($7.30/mo) for Inter-region data delivery from North America to North America.
