What is RabbitMQ? 

**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.

IBM's transparent chalkboard lecture are always the best.

This is a really concise, and well explained introduction to RabbitMQ. Thank you Whitney!

The explanation is so simplified that even a non-IT person will grasp the whole concept of message handling. Well done!!

I like this style of teaching, old school with a modern chalkboard. Well done!

thanks for the concise explanation. been confused about this message queueing system for a while.

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)?

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.

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 your hard work reflects in the content and explanation. I wish I could have you as my cloud trainer

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

Very good overview and precise to the point explanation! I really like all IBM cloud videos. Great for learning and to get started!

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.

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.

Nice explanation, nice presentation. I like how these whiteboard talks are evolving -- they now have animations -- cool.

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.

One of the best explanations about RabbitMQ ever!

Whitney makes it sound so easy.

Love this explanation and now have better understanding of producer/sub model. Thank you.

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.

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!

Really appreciate use of different colors for better understanding...thank you for the video👌

Very good explanation. To understand the necessity to use a message broker in a microservice enviroment and in a scalable enviroment

Just the right level of detail for refreshing/preparing for an interview, thanks!

Wow!! Such a nice explanation. I want to learn every topic from you. Thank you for such a great video.

very well explained , thanks to IBM and Whitney for enabling and explaining this good

my favorite channel. always come here to learning new stuff

Thank you for the very clear and concise introduction!

Thanks for this fantastic explanation of RabbitMQ!

concise, to the point explaination!! awesome. loved it :)

great example of excellent left handed minds and artists, both artistic & technical, righting back-to-front.

oh my god! I was just searching for rabbitMq in IBM this morning.

Thanks: nice way of presentation. Thorough and concise.

Excellent explanation. Really precise and concise.

Wow. Very easy to understand, incredible job.

This was one of the best educational video I have ever seen. thanks!

Thanks for clear and understandable explanation!

Excellent overview! Thank you, Whitney.

Outstanding! Really loved this, great explanation :)

My first thought to this was - wow, she's really good at writing mirrored text!

Good explanation with positive vibes that cached me. Thanks

thank you, it's really concise and easy to understand

Very concise tutorial, thank you.

Super clear explanation! Thanks!!

Just loving your videos! :)

very useful info within 10min. thank you!

That is some serious spatial awareness. Good job for writing mirrored and backward. Great content.

Thank you and can't help thinking how this chalkboard works，does the demonstrator need to write reversely？

Crystal Clear. Thank you.

that's really amazing information.. so clearly explained..

This is awe....some!!! Love it! Thank you!

perfect explanation! thanks for creating this!

This such an amazing explanation. Thanks

Great explanation!

Finally good and full explanation

Good explanation. Thank you!

Amazing tutorial!

That was a great video, have little knowledge of MQTT. This helped.

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?

Very well explained,thanks a lot.

a valuable 10 mins video. thanks for sharing

Execllent overview, thank you!

Amazing work. Thank you!

Amazing explanation, thank you!!

Excellent overview Madam. Thank you very much.

Thanks a lot! Very helpful video 👌

very well explained. thank you

This is great overview. As I have got to know. working on that is not east at all.

please how are these kinds of video presentations made, I really love them

very clearly explained!

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!

HHHM! Nice teaching. I can enroll in all her courses.

Good explanation! Could we have an "What is IBM MQ?" next?

Great video, thank you!

Brilliant stuff team. So on point

Nice 10 min intro for RabbitMQ video to share with team.

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.

nicely explained!

Very good explanation

Nicely explained.

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?

Awesome overview.

love this lecture...

Amazing content. Keep it up!

Thank you for such great video

I was monitoring for some time MQ servers years back, you know alert, admin log in, check services running, restart them if are down, but I was now-years old when I learned how MQ works, back then it was "just another app that had to stay up".

When I seriously listening to this video I thought mouse is moving around my room.thank u for clear explanation

This is really great

great overview

you are awesome lee :)

Relates RabbitMQ to JMS or no? Queue/topic are industrial standard. Implement RabbitMQ it?

This is really good

Thanks for the video .. Info is very clear and crisp

I love this explanation , thank you for saving me lot of time

Well explained

Awesome job

Hi Can you please make a video on difference between kafka and rabbitMQ ?

This is Great 💯

Thank you!!
