IBM's transparent chalkboard lecture are always the best.

**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.

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!!

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

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.

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, 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 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.

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

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

One of the best explanations about RabbitMQ ever!

Whitney makes it sound so easy.

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!

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

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

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.

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

Thanks for this fantastic explanation of RabbitMQ!

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

Thank you for the very clear and concise introduction!

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

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

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

Thanks for clear and understandable explanation!

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

Excellent explanation. Really precise and concise.

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

Crystal Clear. Thank you.

my favorite channel. always come here to learning new stuff

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

Amazing tutorial!

Wow. Very easy to understand, incredible job.

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

Thanks: nice way of presentation. Thorough and concise.

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

Excellent overview! Thank you, Whitney.

Good explanation. Thank you!

a valuable 10 mins video. thanks for sharing

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

Good explanation with positive vibes that cached me. Thanks

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

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

Outstanding! Really loved this, great explanation :)

perfect explanation! thanks for creating this!

Finally good and full explanation

Very concise tutorial, thank you.

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

Super clear explanation! Thanks!!

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

Execllent overview, thank you!

Amazing work. Thank you!

Amazing explanation, thank you!!

Very well explained,thanks a lot.

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

very well explained. thank you

This such an amazing explanation. Thanks

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!

Great explanation!

Excellent overview Madam. Thank you very much.

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

very useful info within 10min. thank you!

Brilliant stuff team. So on point

Thanks a lot! Very helpful video 👌

Just loving your videos! :)

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

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.

very clearly explained!

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

Amazing content. Keep it up!

love this lecture...

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?

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

Nicely explained.

Great video, thank you!

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

Thank you for such great video

nicely explained!

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

Very good explanation

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

Awesome overview.

Well explained

This is really great

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

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?

This is Great 💯

Thank you!!

Awesome job

This is really good

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

you are awesome lee :)

great overview

AAhh....perfect!!

Fantastic explanation, even for a non-programmer like myself

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