Thanks for the guide, as others have said this is good introductory reading for new engineers. I know I really only learned about dedicated message queues 1-2 years into my career and felt really dumb for not having known/thought about message queuing before. One thing you might consider adding are more examples for different popular queuing systems and how they differ from one another. The software I always reach for is nsq (https://nsq.io/ https://nsq.io/) because it's meant to run co-located with the message producers and readers are supposed to connect to multiple instances where the messages are produced (using a lookup daemon). This is quite different from the queues on your list, so much so that I'd consider adding it just because it works so differently.
