Simple Queue Service (SQS) Basics | AWS Cloud Computing Tutorial for Beginners

These days, a lot of applications use a microservices architecture, where the different components are decoupled from each other. But with things decoupled, how do the different parts communicate with each other? The answer is the Simple Queue Service, or SQS. When you think “decoupled” in Amazon Web Services (AWS), think SQS.

In this video, I’ll introduce you to the core concepts of SQS, using an example of a photo processing application. Then in a hands-on tutorial, we’ll create a new queue through the AWS Console, and send and receive a few messages. I’ll also demonstrate how to work with the visibility timeout feature, which prevents messages from being processed more than once.

Thank you - this entire channel is a newly discovered goldmine for me; I just passed with certified practitioner cert and was trying to implement some of the basic features to prepare for dev associate. Very clear explanation, super clear audio, no complex technical jargon I didn't understand as with some other videos.

This is the best explanation of SQS I’ve seen so far in the whole of YouTube.. thanks you 🙏🏾

Thanks Madam ! Pretty clear and concise - All the Message Queue jargon to the point
- Visibility timeout, FIFO, Dead letter queue, Message Payload, Long polling, Max retention.

thanks for the video! it's amazing!

[zeeshanulhaq]

Thank you so much for such and concise and clear explanation. Would love to have a video in SNS also 🙏

Please continue posting and how to contact you if we have any doubts?

Very good explanation. I never seen SQS on youtube. Your is the first video. You explained VPC very well due to which I came to this video, but you really explained it well.

Im preparing for AWS solution architech exam and I failed it last time. So to pass it this time, Im trying to attend the videos.

SQS is a important topic. Can you put more real life examples?

[kakolisen]

Thank you for the wonderful series. Have a question though- why is the receive count for each message increasing every time we poll it? Is that because retention period is 4d?

Your tutorials are amazing. The diagrams are very intuitive. Do you have a course for aws certifications on Udemy?
