Messaging and integrations 🚀☁️ #87

Customer Managed Key support to rule filter patterns and input transformers on EventBridge

Sep 30, 2025

In the previous issue, Refactor with the CDK CLI 🚀☁️ #86 we looked at the new update with CDK Refactor

In this issue, we look at the messaging and integration services on AWS - EventBridge, SQS, SNS, MSK, which help with stitching the complete “event-driven-architectures” with Event Buses, Queues, Topics or Streams that are all purposed for sending messages/events from the producer to subscribers. These services also help with decoupling and ensuring the messages/events are routed to the right subscribers. Speaking about routing, filter patterns are very crucial; now with Customer Managed Key support to rule filter patterns and input transformers on EventBridge.

If you are still worried, when do I use SQS or SNS? This blog post should help you understand it better.
