Cloud Pub/Sub
Cloud Pub/Sub is a fully managed, real-time messaging service provided by Google Cloud Platform (GCP) that enables asynchronous communication between independent applications. It allows publishers to send messages to topics, which are then delivered to subscribers who have registered interest in those topics, supporting decoupled, scalable, and reliable event-driven architectures. It is designed for high throughput, low latency, and global availability, making it suitable for streaming analytics, data integration, and microservices communication.
Developers should use Cloud Pub/Sub when building distributed systems that require reliable, scalable messaging for event-driven patterns, such as in microservices architectures, real-time data pipelines, or IoT applications. It is particularly valuable in GCP environments for integrating services like Dataflow, BigQuery, or Cloud Functions, where decoupling components and handling high-volume data streams is essential. Learning it is crucial for roles involving cloud-native development, data engineering, or serverless computing on Google Cloud.
