I completed all the intermediate courses following the introductory courses. I now have a clear understanding of the roles and connection relationships of AWS network components. Thank you.

I'm a major in this field, but I didn't have a clear understanding of the terminology and concepts. However, your easy explanations help me understand everything perfectly. By learning the theory and doing the practical exercises, I was able to gain a clear understanding. Totally recommend this course!!

This Chuseok, I feel like I've been continuously learning with instructor Jaeseong, and through this AWS course, I experienced "Amazon Web Services" which allows you to easily do on the web what you used to do by typing config commands on routers and switches in actual networks... The kind explanations and multiple repetitions were so good. I'll continue with Jaeseong's next lecture since there's still some holiday time left!

강의상세_배울수있는것_타이틀

  • How to configure a VPC network essential for service operations

  • Methods for improving security using Private Subnets

  • How to prevent server failures using Availability Zones

  • How to configure security groups using the principle of least privilege

  • AWS infrastructure architectures frequently used in the industry

  • VPC, Subnet, Internet Gateway, NAT Gateway, Route Table


🥹 I sincerely thank all the students who supported me 🥹

It's already been a year since I created the introductory AWS course. Before first launching the course, I had many worries, such as whether my explanations were too difficult or what I would do if the students weren't satisfied.

Fortunately, many people took the introductory AWS course, and I remember breathing a sigh of relief after hearing feedback that they were able to understand AWS easily and apply it in practice.

And thanks to the students who encouraged me to keep creating courses, I gained the confidence to create an Intermediate AWS course as well.

In this intermediate AWS course, I will teach you how to improve network security using VPC and how to build infrastructure that increases availability and reduces the probability of server failure.

In the professional world, security is critical, so AWS infrastructure is essentially built by establishing a VPC. The fact that VPCs are used in the field means that you must understand VPC concepts to have a better advantage in employment and to quickly adapt to tasks once you are hired.

In this lecture, I won't just show you how to build a VPC and leave it at that; I will help you understand each concept necessary for building a VPC so that you can apply them to your own project situations. Then, using those concepts, we will build a VPC in the same way it is done in the industry.

I sincerely hope that through this course, you will gain a deeper understanding of AWS and become a developer recognized in the industry. I'll see you in the lectures.



✨ 4 Key Points Focused on While Creating the Course

In the field of development, it is important to prioritize learning knowledge that can be used in the workplace—that is, techniques that are frequently utilized in practice. Therefore, I have structured the course using only concepts that are frequently used in the industry.

If you don't know how to apply what you've learned in practice after finishing the course, then it's a poorly made course. I have structured this course so that you can immediately apply the concepts you've learned to real-world situations after completing it.

I believed that if you cannot apply what you've learned in practice even after finishing the course, then it is a poorly designed course. I tried to structure the course to be practical and immediately applicable to real-world work, rather than taking an academic approach of deeply studying theory.

I didn't create this course by simply showing how to use or implement things without any explanation. I will provide theoretical explanations so that you can build while understanding the principles and concepts. This way, you will be able to apply what you've learned to your own specific project situations.

👍 This course is recommended for the following people!

Those who have watched YouTube or blogs but
are having difficulty with in-depth learning of AWS

Those who are non-majors and
slow to understand difficult
concepts and terminology

Those who want to directly
introduce and utilize AWS
in the field

🙊 What will you achieve after completing this course?

You will be able to configure a secure network using AWS VPC. Additionally, you will learn how to increase availability and reduce the probability of server failure.

Notes

If there are any parts you don't understand while studying, please ask questions immediately using the Q&A board or the 1:1 open chat room😊

🚨 Be sure to check what kind of person the educator is!

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

Due to poor education, you may end up at a company you don't want, receive a lower salary than expected, and suffer for the rest of your life as a result. Not only that, but the poor education you received can even be passed down to your children.

I believe that education can truly change a person's life for the better, but on the other hand, it can also completely ruin a person's life. That is why I believe education carries such a heavy responsibility.

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

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

Hello!

I started studying development as a non-major. Somehow, I've already become a developer in my 6th year! Recently, I served as CTO at two companies while working as a developer. Whenever I had spare time, I've been doing coding lectures, corporate development consulting, and speaking engagements.

The number of students I have taught has already exceeded 24,000 (as of July '25)! As I feel every time I teach my many students, I can never forget the sense of fulfillment that comes from education, so I plan to continue providing courses here on Inflearn.
(* Produced successful applicants for Kakao Pay, Yanolja, and Woowa Bros among students)

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

For these reasons, I hope that by giving and sharing what I have gained through my efforts, those people can live a slightly better life.

Thank you!

            I've come to leave a review after completing the entire jscode roadmap ~~ I was first shocked at how well I understood the AWS introductory course and CI/CD course, and how well I could apply and absorb the knowledge 😊😊 After taking all the courses within a month and studying with amazement each time, I'm finally leaving this review!! As a quasi-major, I had been anxiously studying specific concepts in a haphazard way through project activities without overall understanding, and hastily developing and debugging through blogs and searches without a solid foundation. But after taking Jaesung's courses, I realized that my study method was not efficient 😊😊 I truly consider you a benefactor in my development career The courses were neither excessive nor insufficient, really substantial and perfectly aligned with the course topics and goals, so I enjoyed every moment of listening. I loved that it saved time, was easy to understand, immediately applicable, and didn't make me anxious. Also, I could see how much time and passion you put into every course, always admiring how you covered compact yet detailed elements so well!! I've taken various courses, but unlike other instructors who teach while working full-time jobs, this course where you poured your passion solely into education had incredibly high satisfaction :) I hope you stay healthy always, and I would be grateful if you continue to produce future courses without overexertion 🙇🏻‍♂️
