Learn how to use fan-out messaging patterns with Amazon SNS to build decoupled and scalable distributed microservice architectures.

In this episode, join Sidhartha as he explores an end-to-end order processing application that leverages the pub/sub fan-out pattern using Amazon Simple Notification Service (SNS). You'll see how SNS enables asynchronous communication between microservices by "fanning out" messages to multiple subscribers in parallel.

Discover how AWS messaging services like SNS allow you to build highly decoupled yet cohesive distributed applications without worrying about complex messaging logic. Build resilient and scalable cloud-native apps using modern serverless patterns!
