AWS Messaging Comparison

This lesson is part of AWS · All levels

Summary

This lesson compares AWS messaging services: SNS for publish/subscribe patterns that push messages to multiple recipients, SQS for queues that consumers pull at their speed, and EventBridge for event buses with filters and scheduling. Understanding the differences helps to choose the right service to suit architectural needs. A combination of SNS and SQS is often used for reliable fan-out patterns.

Key points

SNS pushes messages across the subscriber topic
SQS holds messages until they are pulled by the consumer (pull)
EventBridge excels at complex filters and task schedules
The SNS+SQS pattern allows fan-out to many systems
