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 decouples senders (publishers) and receivers (subscribers) to enable scalable, reliable, and low-latency communication across distributed systems. It supports both push and pull delivery models and integrates seamlessly with other Google Cloud services for data processing and analytics.
Developers should use Google Cloud Pub/Sub when building event-driven architectures, microservices, or streaming data pipelines that require high throughput and global scalability. It is ideal for use cases such as real-time analytics, IoT data ingestion, log aggregation, and decoupling components in cloud-native applications, as it ensures message durability, at-least-once delivery, and automatic scaling without infrastructure management overhead.
