Google Cloud Pub/Sub
Google Cloud Pub/Sub is a fully managed, real-time messaging service that allows independent applications to send and receive messages asynchronously. It provides reliable, many-to-many, asynchronous messaging between applications, decoupling senders (publishers) from receivers (subscribers). It is designed for high throughput, low latency, and global scalability, supporting event-driven architectures and streaming analytics.
Developers should use Google Cloud Pub/Sub when building distributed systems that require reliable, scalable, and real-time message passing, such as in microservices architectures, IoT data ingestion, or event-driven applications. It is particularly useful in scenarios where you need to process high volumes of events with low latency, integrate with other Google Cloud services like Dataflow or BigQuery, or implement decoupled communication between services across different regions.
