SNS vs SQS Comparison? Whats the difference? | Learn with a practical example

I came looking for copper and found gold. Thanks.

Thank you sergio for such a kind comment!

same!

Much precious than gold

[@sf-spark129]

Good explanation!! As an active user of AWS myself, I would like to add one thing here. SQS is not error-proof/fault-tolerant by itself in the event of a failure. It guarantees to deliver all messages to the next microservice by having a back-up option, called DLQ(Dead Letter Queue). When the SQS fails to deliver a message to the next microservice whether due to a source side issue or a destination side issue, it sends that message to the DLQ(it is basically another SQS). Then, you get to re-drive(re-play) that message once you locate and resolve the issue in the system. One caveat is that there is a maximum 14-day message expiration period in DLQ. Also, SNS can be subscribed by a streaming service like Kinesis FH.

2:16 - 2:47 - That was a penny dropping moment for me. What an excellent way to describe the difference. Many thanks.

This video did so much that the AWS Academy did not in this regard, and I really appreciate that.

[@davidalexander8786]

SNS is a stateless message service and sqs is a state-full service that queue messages to decouple big APIS into a distributed system that can be resilient to lots of recurrent tasks

[@janithmalinga5765]

Very good practicle example.

[@cazino4]

Great video, clear concise and informative. Would like to see a video that compares SNS to Kafka....

[@markusfeljofsen8345]

What an awesome explanation! Love it.

[@HeavensMeat]

Not sure I understand 8:40 mark, you're saying if a lambda is subscribed to SNS, you can potentially lose the message if there is a problem with your logic whereas in SQS you do not... So what is the advantage to lambda? I'm guessing that it is that lambda runs right away vs waiting for some service to poll it to send that reminder service (which would take longer) Another question I have is, how do you ensure a message gets processed when it is decoupled? Let's say one of them didn't process, then wouldn't you have to repub the SNS topic which would send it to all the other processes subscribed and then you would have duplicate messages sent to the ones that didn't mess up which would just be a different assortment of issues?

[@BeABetterDev]

Hi HeavensMeat, Good questions! Regarding the first one (message loss via SNS -> Lambda): As per aws.amazon.com/sns/faqs/#Reliability - "If Lambda is not available, SNS will retry 2 times at 1 seconds apart, then 10 times exponentially backing off from 1 seconds to 20 minutes and finally 38 times every 20 minutes for a total 50 attempts over more than 13 hours before the message is discarded from SNS." Effectively this means your message could be potentially lost if your lambda starts failing. Regarding ensuring a message gets processed: You are quite right that if one of your subscribers fails, you potentially would need to republish to the source SNS which can cause problems for other clients as you described. In order to prevent this, clients should always be able to handle message de-duplication either by using timestamp comparisons or some kind of versioning system to ensure they can handle this situation. There are of course other options such as invoking the affected client manually through some kind of script with the backlog of data that they failed to process.
