Is the fanout pattern using AWS SNS ans SQS reliable?

Question

AWS blog says that it supports the fanout messaging pattern. To do that, I subscribe SQS queues to a SNS topic.
Now my question is, is the publishing of message to SQS by SNS reliable? As in, is it guaranteed that the SNS will always successfully post a notification (message) on all SQS queues that are subscribed, upon every post to SNS?

Answer 1

I believe this is a guaranteed service, at least that's what I was told last time I met with the SNS/SQS team. We make use of SNS->SQS bindings quite heavily
