First-come, first-served event architecture 🚩
Many services often run events like "Special discount coupons for the first 300 customers." This leads many backend developers to implement first-come, first-served event systems for their business domains. However, without actual experience implementing such systems, it's difficult to grasp how to design them.
I, too, had questions about how to design first-come, first-served events when I was preparing for employment, but it wasn't until a long time after I got a job and began building my career as a developer that I finally found the answer.
So, in this lecture, we'll explore potential problems and solutions when building a first-come, first-served event system. To help novice backend developers who, like me, have similar questions, I've designed this lecture to provide hands-on experience developing a simple first-come, first-served coupon event system, allowing you to directly experience the challenges you'll encounter in real-world work. So, let's explore together!

💡You will learn about the problems that can arise when implementing a first-come, first-served system and how to solve them.
What is the cause and how can I fix it?
How can we prepare in advance?
So, you can do things like this!
- ✅ As you gradually build a first-come, first-served event system, you will learn what problems arise at each stage and how to solve them .
- ✅ Configure Redis and Kafka in a Docker environment and practice the commands mainly used in the project.
Q&A 💬
Q. I've learned the basics of Java. Can I still take this course?
This course is intended for those who have experience working on a project using Spring + Java.
Therefore, we recommend that you take the course after working on a project such as a bulletin board.
Q. I only have experience developing with Node.js and JavaScript. Can I still take this course?
This course is based on Spring + Java and does not provide additional explanations about Spring or Java.
However, as long as you can understand Spring + Java-based code, you can take the course.
Q. How in-depth is the coupon system?
While this lecture covers the topic of coupons, it doesn't delve into them in depth. Please note that this is primarily intended as an example of a first-come, first-served event.
💾 Please check before taking the class.
- I am using macOS and IntelliJ as my practice environment.
- This course is intended for those who have experience creating a bulletin board or simple project using Java, Spring, and JPA. (Java, Spring, and JPA will not be covered in detail.)
A great lecture to watch together 📺

100% enrolledThe lecture is good, but it is only an introductory class. Please purchase it knowing this. If you are someone who uses Ladies and Kafka in practice, you probably don't need to purchase it, and if you don't know anything at all, you can just buy it to skim the introductory course. And if you are a job seeker, if you write this much and write one line on your resume, you will be able to avoid in-depth questions during the interview. You should study separately.

hallo, thank you for your detailed course review! As you said, this course uses Redis and Kafka at an introductory level, so if you want to use it in practice, I recommend you study it in depth! Thank you for your kind words :)

100% enrolledI've quit the company now, but... When I actually ran the first-come-first-served 100 coupon event, the DB died... Whenever someone tried to issue a coupon and order, it took 5 seconds to load the page... I remember the chaos.. In the end, I had to deal with it by increasing the temporary ec2 instance and the db server, but if I had seen this lecture before, I would have suggested it and reflected it myself.. I could have had a good experience.. Now that I'm trying to test it myself.. The server cost is not cheap, and I'm very sorry.. I hope this lecture spreads widely so that people like me won't have regrets... I listened to the lecture well. Thanks to you, I became interested in Redis and Kafka, and I want to study more. Thank you.

100% enrolledI am so grateful that you taught me difficult content with practical code! It was a neat lecture! It would be better if you uploaded Notion as a lecture material all at once. It was a bit cumbersome to go into each lecture when reviewing. However, the lecture content is very informative. It is the best.

Thank you for the course review, Soyoung Choi! I will take the time to organize the lecture materials and upload them. Thank you!

100% enrolledI learned new knowledge, and I think I can get additional direction through this. It was good that only the key points were explained in one hour, but I was disappointed that the concept was briefly covered at the end.
- 169developer9973Instructor
Thank you for your course review, Mr. Lee Jin-woo! I tried to convey it in a short period of time, so I think it was a little lacking. If you ask questions on the Q&A board about the parts that were lacking, I think I can answer any questions you have!
