In my opinion, SQS shouldn't be on that list. You save a lot of time and resources just using SQS instead of setting up your own servers. And the lock-in is not as problematic as Lambdas etc. It doesn't require much code change to move to an alternative message queue (RabbitMQ etc.), so the lock-in is minimal. In my projects, I just need to change a few lines of configuration code and the actual message processing code should remain the same.
