BUTSNS 有缺點

AWS SNS

Notify in near-real-time to a subscriber that a message has been published. However, SNS can only guarantee a single delivery to each subscriber of a given topic. This means that if there was a bug or a problem processing the message and there was no specific code to save it somewhere, then the message lost.

How to makr it more reliable

SQS ＋ SNS to send identical copies of a message to multiple queues in parallel for simultaneous processing.
