What is the difference between Amazon SNS and Amazon SQS?

Question

Please explain the main difference between Amazon SNS and Amazon SQS and where can I use these as I'm a bit confused about the exact places for using them.

Answer 1

SNS: In aws sns the messages are pushed to subscribers as they were sent from publishers to SNS. It is also known as distributed- subscribe system.

                                  SNS

SQS: It does not push messages to receivers and they have a poll to receive messages. Messages aren’t received by multiple receivers simultaneously. This is also known as distributed queuing system.

                                   SQS
