Cloud Pub/Sub

Microservices are great for speeding up development and improving code quality. But as your service network grows, complex communication can slow things down. Integrating new teams becomes a meeting marathon, and scalability suffers.

Introducing Async Communication with Pub/Sub

The answer lies in asynchronous communication. Services can “publish” events to a central messaging system, and other services can “subscribe” to listen for those events. This decouples services, making them independent and highly scalable.

Enter Pub/Sub: Your Messaging Powerhouse

Pub/Sub is Google Cloud’s fully managed messaging service that offers two flavors:

• Pub/Sub: Perfect for real-time analytics, Pub/Sub delivers serverless, auto-scaling messaging and event ingestion. It allows geographically diverse publishers and subscribers (up to 10,000 per topic!) to connect and exchange information independently, with separate billing for each. Plus, it supports push delivery, making it ideal for communication between microservices.
• Pub/Sub Lite: Cost-conscious? Pub/Sub Lite prioritizes affordability, offering up to 90% cost savings compared to Pub/Sub. However, it requires you to manage capacity and offers less storage.
