What you will gain after the course

  • Query Performance Optimization Methods You Can Apply to Your Project

  • Frequently Used Redis Utilization Methods in Practice

  • Redis Basic Usage

  • How to Utilize Redis's Caching Feature

  • Performance Comparison Using Load Tests


Notice (25.08.11.)

Hello! This is Park Jaesung from JSCODE :)

After taking the Redis course, from the perspective of some students

It seems that disappointment often occurs when things don't meet expectations 😭

I hope that fewer people will be disappointed through the lectures

So you can make a wise purchase, before buying the course

I've compiled some content that would be good for you to check!


  1. Structure of the Course
    This course is not a lecture that deeply explores Redis concepts.This course focuses on the basic usage of Redis and is designed to concentrate on how to apply and deploy Redis in actual projects. It also includes the process of verifying through load testing whether performance has truly improved when Redis is applied.

    Just in caseI recommend that you definitely check the curriculum before purchasing the course, as the content you're expecting may not be included in that particular course.We're giving it to you!

    (Next time, I'll create an additional lecture focused on Redis, so you can learn in-depth concepts and application methods of Redis in a focused way! 😭😭)



  2. Lecture Time


    This course is relatively short compared to other courses I've created3 hours of content's lecture.



  3. Price Adjustment
    I believe this course is priced too high relative to its content volume. Therefore, for those who purchase it in the future, please use the link below to get a 30% discount coupon before making your purchase!

The lectures that come after this will be given a bit more attention

A course that can satisfy as many students as possible

I will do my best to make it possible!


Thank you.

JSCODE Park Jaesung's regards.




🤬 Damn it, I can't do this anymore!

I'm Park Jaesung, who started development as a non-major and worked as CTO at various companies, and am currently working as an educator. I also started development as a non-major and had a time when I was studying Redis.

When I first tried to study Redis, I was overwhelmed about where to start. Most books and lectures explain Redis data structures (string, list, hash, Set, sorted Set, etc.) and endlessly go through countless commands (SET, GET, EXISTS, DEL, HSET, etc.). So I couldn't shake the question from my mind: 'When will I ever learn all of this, and how do I actually use it in real-world situations?'

Somehow I thought 'I should try using Redis to improve performance' and introduced Redis. It definitely seems like the speed has improved, but I wondered how much faster it got, how to test it, and whether I applied it properly. As a result, I lost confidence in applying it to actual projects.

Since I also went through a period of experiencing such anxiety and difficulties, I thought I should create a Redis course that non-majors can easily apply directly in real-world situations.

✨ 4 Points I Focused on While Creating the Course

Once we've learned the concepts, we need to directly experience applying Redis in practice using those concepts. Therefore, I've structured the course so you can directly experience the most commonly used Redis cases in the field.

We'll teach you only the essential core concepts you need when using Redis to improve query performance. Just knowing a few frequently used concepts is enough to master Redis and improve performance. We won't teach you unnecessary concepts. Learning this way, you can truly learn quickly and apply it immediately in real-world situations.

I thought that if you can't apply what you've learned in real situations even after completing the entire course, then it's a poorly designed course. I tried to structure it as a practical course that can be immediately applied to real work, rather than an academic approach that focuses on deep theoretical learning.

We won't just explain theory, but will show you step by step how to improve performance using Redis with examples. By showing you this improvement process, you can easily learn what steps to take to improve performance using Redis in real-world situations.

👍 Great for people like this to take!

Those who are having difficulty
learning Redis by watching YouTube or blogs

Someone from a non-major background who
has slow understanding of
difficult concepts and terminology

Those who want to introduce Redis in their work
and improve performance

🙊 What happens after you finish listening to this entire lecture?

You will be able to learn basic concepts about Redis. Additionally, you will learn how to optimize query performance using Redis in real-world applications.

Reference Notes

The class proceeds under the assumption that you have basic knowledge of Spring Boot. Therefore, I recommend taking this course after learning basic Spring Boot. However, even if you don't know Spring Boot well, you should be able to learn sufficiently by utilizing the 'annotation study method' that will be explained in the lecture. If you encounter any parts you don't understand while studying, please feel free to ask questions immediately using the Q&A board or 1:1 open chat room😊

🚨 Make sure to check what kind of person is providing the education!

If you meet the wrong doctor, you might face death because your illness can't be cured at that moment. But death ends with the pain of that moment. However, if you meet the wrong teacher and receive poor education, you will suffer throughout your entire life.

Wrong education can lead you to an unwanted company, receive a smaller salary than expected, and potentially suffer for the rest of your life as a result. Not only that, but the wrong education you received can also be passed down to your children, perpetuating the cycle of poor education.

Education can truly change a person's life in a positive way, but on the other hand, it can also completely ruin a person's life. That's why I believe education carries such heavy responsibility.

Therefore, please check who is providing the education, what kind of person they are, and what path they have walked, and make a careful judgment.

👋 Hello!
I'm finally introducing myself now ( ⸝⸝•ᴗ•⸝⸝ )੭⁾⁾

Hello!

I started studying development as a non-major. Before I knew it, I've already become a 6-year developer! Recently, I've been working as a developer while serving as CTO at two companies. Whenever I have time, I've been doing coding lectures, company development consulting, and presentations.

The number of students I've taught has now exceeded 24,000 (as of July 2025)! Every time I teach various students, I always feel the same way - I can't forget the sense of pride in education, so I plan to continue providing education consistently on Inflearn.
(* Among students, successful candidates for Kakao Pay, Yanolja, and Woowa Brothers have been produced)

Just as I received a lot of help during difficult and challenging times, I wanted to become someone who could help many other people as well. And I felt most proud and happy when the value I created through development had a positive impact on others.

For these reasons, I hope that by giving and sharing what I have worked hard to achieve, those people can live a little better life.

Thank you!

    It has the advantage that you can quickly learn the basic usage of Redis, performance testing, and even AWS related settings. However, the disadvantage is... frankly, the price is a bit steep compared to the lecture time.

      Thanks to Jaeseong, I learned how to use AWS + Docker + Redis(ElastiCache)! Now I'm going to learn more about Redis mode, failover, Transaction, pub/sub, etc. Thank you~!!
