What is RabbitMQ? 

IBM's transparent chalkboard lecture are always the best.

I wish 10% of technical videos of this kind were as good as this one. Content, pace, delivery, and relevance were all exemplary. No nonsense "X in 100 seconds" approach. Good to see there are still great teachers who only need a board to draw on to explain things well and effectively. Thank you, you have a new subscriber.

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

This is one of the best explanation of general messaging systems & RabbitMQ so far! Great job!

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

**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.

the calmness when explaining is appreciated

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

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.

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

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

Finally I've found a video that well explains message queues

Whitney makes it sound so easy.

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 perfect! I didnt even know what a message broker was and after this, I have something solid to start with. Thank you Whitney!

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

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

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

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

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

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)?

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

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

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

Crystal Clear. Thank you.

I cant believe how casual she's writing backwards .. well explained ! Thx

One of the best explanations about RabbitMQ ever!

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

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

Thank you for the very clear and concise introduction!

a valuable 10 mins video. thanks for sharing

very useful info within 10min. thank you!

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

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

That fact that she is writing inverted so fast is mind-blowing.😄

Concise and well explained. Thanks

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

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.

Great explanation!

Anyone noticed she's actually writing the mirror image ?

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

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.

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

Good explanation with positive vibes that cached me. Thanks

Thanks: nice way of presentation. Thorough and concise.

Excellent overview! Thank you, Whitney.

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

Thanks for this fantastic explanation of RabbitMQ!

This such an amazing explanation. Thanks

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

Very concise tutorial, thank you.

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

perfect explanation! thanks for creating this!

Thanks a lot! Very helpful video 👌

I'm mesmerized more on how easily she writes backwards from her perspective.

really well explained !!

Excellent overview Madam. Thank you very much.

Super clear explanation! Thanks!!

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?

Excellent explanation. Really precise and concise.

Good explanation. Thank you!

Well explained

Very good explanation

How the heck did you learn to write backwards - nicely done 😊

Very good explanation👌👌

Is she writing backwards or is there some tech sorting that out? Mind Blown.

Outstanding! Really loved this, great explanation :)

Awesome overview.

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".

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?

Wow. Very easy to understand, incredible job.

#Explain Like I’m 5! Awesome explaination Whitney.

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

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

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

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.

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

Great explained, Can you please also make video on "jenkins" ? It will be very helpful

She proposed three benefits of RabbitMQ decouple scalable performant In 2023 when I can deploy containers to something like AWS ECS, how much of and issue is “scalability” and “performance”?

great overview

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

Fantastic explanation, even for a non-programmer like myself

Whitney needs to be in the Guinness book of record for her excellent teaching skills. well articulated

This is really great

Awesome job

Good overview

Innovative old school teaching.

This is really good

Thanks for clear and understandable explanation!

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

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?

Brilliant stuff team. So on point

Just loving your videos! :)

Very well explained,thanks a lot.

Amazing tutorial!

This is Great 💯

Thank you for such great video
