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.

Using SQS is that it requires polling which introduces a certain delay between the time a message is published and until it is processed. That delay can be small, a couple of seconds, but can easily be up to 30 seconds and more.
