What is Rabbit MQ? And what makes it one of the most popular message brokers out there?
In this lightboard video, Whitney Lee with IBM Cloud, answers these questions and much more as she visually shows the flexibility RabbitMQ provides enterprises as the move their messages through a system as well as the benefits of it being cloud friendly.

#RabbitMQ #MessageBroker #IBMCloud - วิทยาศาสตร์และเทคโนโลยี
**Summary**
*Background:*
- A message queue will help in *decoupling* two components (e.g. checkout and inventory)
- Components can *scale* based on demand
- Queue sits on a different machine and can offload some of the work of components and make it more *performant*
*RabbitMQ:*
- It is based on the AMQP message model.
- Producer produces the message to exchange instead directly to the queue.
- exchange can be connected to many queues
- Queues are connected to the consumer by a binding key
- Flexibility is a large part of the model
- Different types of exchange
- Fanout
- the message is duplicated to all the queues
- Routing Key
- sends to queue matching the exact binding key
- Topic
- matches based on topic e.g. message is sent from routing key "ship.shoes" and binding key "ship.any"
- Header
- messages are moved through the system-based header
- Default (specific to RabbitMQ not part of AMQP)
- matches the routing key with the name of the queue e.g. "inv" routing key matches the "inv" queue name.
- the consumer has the control, not the message broker, they define the message metadata
- it is cloud-friendly
- easy to get started
- can be deployed in a container e.g. docker
- can run on the cluster (fault-tolerant, highly available and high throughput)
- It has good library support in many languages.
- It has good security supports FASL, LDAP and TLS.
- It supports message acknowledgements
- Good management and plugins.
Are Headers and Labels the same thing?
IBM's transparent chalkboard lecture are always the best.
she really is writing mirrored letters? 😶
She is right handed btw 🤷
@@Suraj-tz3oq thats insane
The board is actually towards themselves. So in the end they mirror the screen.
Yeah transparent. Even the writing is transparent. Can't see anything.
This is a really concise, and well explained introduction to RabbitMQ. Thank you Whitney!
I like this style of teaching, old school with a modern chalkboard. Well done!
The explanation is so simplified that even a non-IT person will grasp the whole concept of message handling. Well done!!
I wanted to learn the basics of RabbitMQ and this video is just great for that. I value the fact that the instructor went over the basics of the messaging queue and the underling aspects such as the exchange and how that relates to the queues that are named with a tag. Other videos talk about asynchronous communications and then jump into a code example. You can explain the concepts of something without going immediately into one of many implementations. Thanks.
Glad it was helpful!
Whitney your hard work reflects in the content and explanation. I wish I could have you as my cloud trainer
Thanks, Whitney and the entire production team. I really like these videos that explain the crux of the stuff in less time. I'm interested in learning more about this. Can you recommend books or any other sufficiently complete resource(s)?
These videos always look so cool
I don’t know who had the idea to design them that way but it was genius, they always stand out
This is a great and concise source for getting to know RabbitMQ but I'm more impressed by the fact that she can inversely on a transparent whiteboard so that a camera on the other side can read it.
thanks for the concise explanation. been confused about this message queueing system for a while.
Haha, I was going to bed planning to check this out the next morning ... and here I am watching your new video. Thank you, IBM team for the another video which is both on point and on time.
So did I haha!
so am I hhh
This is very concise and amazing. I love the video. Never knew when I got to the end of it. 😄. Thank you to the entire production team.
Hey there! Thanks a lot for your feedback, glad you enjoyed it! 😃
awesome presentation. Today I got it completely, my confusion was about how it's handled lots of messages, but now it got resolved. Thanks, Whitney
Whitney makes it sound so easy.
Finally I've found a video that well explains message queues
This is perfect! I didnt even know what a message broker was and after this, I have something solid to start with. Thank you Whitney!
You're welcome, thanks for watching! 👍
Nice explanation, nice presentation. I like how these whiteboard talks are evolving -- they now have animations -- cool.
One of the best explanations about RabbitMQ ever!
Very good overview and precise to the point explanation! I really like all IBM cloud videos. Great for learning and to get started!
That is some serious spatial awareness. Good job for writing mirrored and backward. Great content.
lol they just mirror the video :p
Just the right level of detail for refreshing/preparing for an interview, thanks!
Glad this was helpful, good luck with your interview! 🤞 💪
Thank you very much Whitney. I enjoyed this video very much. It is very informative and has all the relevant details in 10 minutes. Very concise and well explained.
Very good explanation. To understand the necessity to use a message broker in a microservice enviroment and in a scalable enviroment
my favorite channel. always come here to learning new stuff
Really appreciate use of different colors for better understanding...thank you for the video👌
Love this explanation and now have better understanding of producer/sub model. Thank you.
great example of excellent left handed minds and artists, both artistic & technical, righting back-to-front.
very well explained , thanks to IBM and Whitney for enabling and explaining this good
Thank you for the very clear and concise introduction!
My first thought to this was - wow, she's really good at writing mirrored text!
concise, to the point explaination!! awesome. loved it :)
oh my god! I was just searching for rabbitMq in IBM this morning.
Wow!! Such a nice explanation. I want to learn every topic from you. Thank you for such a great video.
This was one of the best educational video I have ever seen. thanks!
Thanks for this fantastic explanation of RabbitMQ!
Excellent explanation. Really precise and concise.
I cant believe how casual she's writing backwards .. well explained ! Thx
Lol, Initially I thought the same. But that's called a "Lightboard". They write on a glass and the Video is then mirrored. Check these out:
th-cam.com/video/VhtEmcNWtyg/w-d-xo.html
th-cam.com/video/wCOuu0-o5YI/w-d-xo.html
She is not writing backward. She is using lightboard.
Outstanding! Really loved this, great explanation :)
Wow. Very easy to understand, incredible job.
Thanks: nice way of presentation. Thorough and concise.
Nice 10 min intro for RabbitMQ video to share with team.
Excellent overview! Thank you, Whitney.
Good explanation with positive vibes that cached me. Thanks
Finally good and full explanation
Thanks for clear and understandable explanation!
Super clear explanation! Thanks!!
Crystal Clear. Thank you.
Very concise tutorial, thank you.
very useful info within 10min. thank you!
Just loving your videos! :)
thank you, it's really concise and easy to understand
In which scenarios, use of rabbitMQ is necessary? Should call to other api should be done via rabbitMQ or just direct http request without the broker?
perfect explanation! thanks for creating this!
This such an amazing explanation. Thanks
Good explanation. Thank you!
Thanks for the video. A comparison of message queues and other publish/subscribe systems (e.g. Apache kafka) would be very helpful for beginners like me.
Thanks for the feedback, let us think about it. Stay tuned! 🙂
Amazing tutorial!
Great explanation!
That fact that she is writing inverted so fast is mind-blowing.😄
Or they just flip the entire video afterward
This is awe....some!!! Love it! Thank you!
When I seriously listening to this video I thought mouse is moving around my room.thank u for clear explanation
That was a great video, have little knowledge of MQTT. This helped.
a valuable 10 mins video. thanks for sharing
that's really amazing information.. so clearly explained..
Amazing explanation, thank you!!
Thank you and can't help thinking how this chalkboard works，does the demonstrator need to write reversely？
Good explanation! Could we have an "What is IBM MQ?" next?
This is great overview. As I have got to know. working on that is not east at all.
Execllent overview, thank you!
Very well explained,thanks a lot.
Amazing work. Thank you!
Thanks a lot! Very helpful video 👌
Excellent overview Madam. Thank you very much.
very clearly explained!
very well explained. thank you
Brilliant stuff team. So on point
HHHM! Nice teaching. I can enroll in all her courses.
Awesome overview.
Very good explanation
nicely explained!
I love this explanation , thank you for saving me lot of time
You're welcome, Santhosh, glad you found it useful! 😀
love this lecture...
Awesome. Now I have a great RabbitMQ intro-video to hand-out to my team ;-) Just one tiny thing: The topic part could confuse some people since the usage of "wildcards" is not mentioned (only implicitly). Or maybe I have overseen something? Thank you for the great work!
So do you write reverse? Or some sort of video processing magic? I am trying to figure out if I want to make such videos for some of the kids I teach, how can I do it?
I imagine all you need is a transparent board in between the camera and yourself, and you write normally, then in post-production, you flip the video horizontally such that it will appear you are left-handed when you are right-handed for example (as is the case in this video).
Notice she writes with her left hand. Most likely, the video was horizontally flipped.
Great video, thank you!
Nicely explained.
Thanks for the video .. Info is very clear and crisp
Thanks for watching! 🙌
please how are these kinds of video presentations made, I really love them
No wonder I got wrong part delivered. It turns out it wasn’t available in inventory. Even though, displayed as available.
So all those messages flowing between systems with outdated information. So, what it is scalable? You cannot guarantee information integrity with messaging.
Thank you for such great video
Amazing content. Keep it up!
If both the inventory and the shipping consumers subscribe to the same queue as described than will they both receive all messages? I think the answer is that they will not because RabbitMQ is designed to load balance between consumers. So inventory will receive one message and shipping will get the next message. So how can we ensure that multiple subscribers can get the same message?
Hello, I would liketo ask if it is a good practice to have a message consumer in frontend web app?
I suppose no, because in this way the rabbitmq server's credentials could be seen by everyone and so anyone could consume your information as well, right?
you are awesome lee :)
Awesome job
Is RabbitMQ really so cloud friendly. Surely it needs persistent volumes to hold onto all those messages if deployed on Kubernetes or Docker Swarm? I would hope those messages are not persisted within a local docker container file system, as containers needed to be treated like cattle. We need to b assured that no data is lost even if there are container and pod runtime failures.
Relates RabbitMQ to JMS or no? Queue/topic are industrial standard. Implement RabbitMQ it?
Fantastic explanation, even for a non-programmer like myself
We're glad you found it useful and easy to understand, Adam! 👍
This is really great
