Cloud Pub/Sub
Cloud Pub/Sub is a fully managed, real-time messaging service provided by Google Cloud that enables asynchronous communication between independent applications. It allows publishers to send messages to topics, and subscribers to receive those messages via subscriptions, supporting high-throughput, low-latency data streaming and event-driven architectures. It is designed for scalability, reliability, and global availability, making it suitable for distributed systems and microservices.
Developers should use Cloud Pub/Sub when building decoupled, scalable applications that require reliable message delivery, such as in microservices architectures, real-time analytics, IoT data ingestion, or event-driven workflows. It is particularly valuable for scenarios where you need to handle high volumes of data with low latency, ensure message durability across regions, or integrate with other Google Cloud services like Dataflow or BigQuery for processing.
