SQS

When EventBridge cannot deliver a message to a target, there are several ways to get notified. In this blog we discuss an approach of using a dead letter queue

When EventBridge needs to deliver messages to SQS, depending on cross account or cross region, the solution is different.

SQS supports both in-transit and server side encryption. For serverside encryption, you can from SSE-SQS or SSE-KMS. What exactly is suitable for you depends on your requirement. In this blog, I focus on how to choose the correct SSE method for cross account access.

Step Functions - one of the main Serverless services offered by AWS for workflow orchestration - does not support dead letter queues natively. This is how we can work around to use DLQ with Step Functions.

This explains a way to implement custom retry logic with SQS and Lambda.

In this blog, it is discussed how Lambda concurrency is determined when a SQS FIFO queue is configured as the trigger.

In this blog post, explains how a Lambda based Serverless application reacts to the errors and attempts to re-drive messages to the origin in a controlled manner.

This blog post shows how we can split messages in a SQS queue into mulitple queues usint Amazon EventBride
