RabbitMQ Explained - Use Cases

Let's take a closer look at some RabbitMQ use cases. Mainly to help you get a better understanding of the benefits of using a Message Queue.

RabbitMQ is a traditional pub-sub message broker (publish-subscribe), meaning one part of the system is communicating with another part of the system through a Message Queue.

Some use cases we will go through in this video include:

- Using RabbitMQ to make reliable backups
- Using RabbitMQ to scale images
- Using RabbitMQ to scan uploaded files
- Using RabbitMQ to generate PDFs

Outro: (4:07)

By using a Message Queue you allow your application to respond to requests quickly and save the heavy lifting for later. Thanks to this queue the application is not being forced to perform resource-intensive tasks immediately - something that would heavily affect the response time.

RabbitMQ allows Producers and Consumers to be located at completely different servers. And a message can be requested from an application built in one programming language, which is later handled by a microservice written in another programming language. So basically, the different parts of the system will only communicate through the message queue. This RabbitMQ architecture results in low coupling between the services which in turn makes the application more robust, easier to scale, develop and maintain.

RabbitMQ is a perfect middleman/broker between microservices.

Finally a true use cases of RabbitMQ, thanks

[codeaperture]

Kindly continue maintaining this YouTube channel. We have less resources on microservice architecture

Finally video where we could hear some real time examples : ] not all heroes wear cape :D

Shield maiden Lagertha teaching us RabbitMQ, What a time to be alive :D

[abdurahmanmohamed]

I’m glad to say that I finally know where I can use RabbitMQ.
Thanks a lot 😃

[jimcollins]

Excellent. I always said "this sounds cool, but when would you use it?" . TIL!

[KARTHIKPRABHUN]

simple and straight forward explanation, Thanks

[hasanaydemir]

Finally got it. Thanks for clear expression :)

[jasonm]

Thank you for providing these examples!

[shaddydxd]

This was really helpful! :) Thanks a lot, and keep up the good work :D

[wolfgang]

thank you very much !! such a great explanation !!

[gabrielnzete]

thanks, simple and direct explanation.

[mikhaillynn]

Nice vid! I think Imma use rabbit in somma my arshitectures soon!

[Roozbeh]

thanks so much, it's good defenition

[elyu_vibes]

Can I use RabbitMQ for sending data from a mobile app into the server?

[kenjohnsiosan]

Really helpful...

Question: Message Queue is a WEB API design for high-intensive task? That when done synchronously will delay the request-response process?

Thank you.

[paulseebach]

Why don’t use Kafka instead of rabbitmq here?

[USONOFAV]

You site step by step coding instruction doesn't have java?

[BemusedSoliloquy]

that's what i call marketing, gg :D
