🥹 I sincerely thank all the students who supported me 🥹

It's already been a year since I created the AWS introductory course. Before I first opened the AWS course, I had many concerns such as whether I explained it too difficultly and what to do if the students were not satisfied.

Fortunately, I remember sighing in relief after hearing many people take the AWS introductory course and leave reviews saying that they were able to easily understand AWS and apply it in practice.

And thanks to the students who cheered me on and said they wanted me to continue making lectures, I was able to confidently create an intermediate AWS lecture .

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

When you go to the field, security is important, so VPC is essential to configure AWS infrastructure. The fact that VPC is being built and used in the field means that you should also know the concept of VPC to be a little more advantageous in employment, and it also means that you can quickly adapt to work when you get a job .

In this lecture, we will not simply teach you how to build a VPC and end it there . We will teach you each concept necessary to build a VPC so that you can apply it to your project situation. And we will use those concepts to build a VPC in the same way that it is built in the field .

I sincerely hope that through this lecture, you will be able to understand and handle AWS in more depth, and become a developer recognized in the field. Then, I will see you in the lecture.



Four points I paid attention to while creating the lecture

In the field of development, it is important to first learn practical knowledge, that is, skills that are widely used in the field. Therefore, I organized the lectures by utilizing only concepts that are frequently used in the field .

If you don't know how to apply the concepts in real life after listening to the lecture, then it is a poorly made lecture. The lecture is structured so that you can immediately apply the concepts you learned in real life after listening to the lecture .

I thought that if you can't apply what you've learned in class, then it's a bad class. I tried to structure the class so that it's practical and can be applied directly to the field, rather than an academic style that focuses on learning theories in depth .

I did not create the lecture in a way that simply shows how to use it or how to implement it without any explanation. I will provide theoretical explanations so that you can build it while understanding the principles and concepts . That way, you can apply it to your project situation.

You will learn how to build a secure network by leveraging AWS's VPC. You will also learn how to increase availability and reduce the probability of server failure .

Note

If you come across any part you don't understand while studying, please use the Q&A board or 1:1 open chat room to ask questions right away 😊

🚨 Be sure to check who is teaching you!

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

Due to wrong education, you may end up going to a company you don't want to work for, receiving a salary that is lower than you expected, and living a life of suffering because of it. Not only that, but because of the wrong education, your children will also inherit the wrong education.

I think that education can really change a person's life in a positive way, but on the other hand, it can also completely destroy a person's life. I think that's why education is such a heavy responsibility.

Therefore, please check who the person teaching you is, what kind of person they are, and what path they have taken, and then make a careful decision.

👋 Hello!
Now I introduce myself ( ⸝⸝•ᴗ•⸝⸝ )੭⁾⁾

hello!

I started studying development as a non-major . I have already been a developer for 6 years! Recently, I have been working as a developer while serving as CTO at two companies . Whenever I have free time, I have been giving coding lectures, consulting on company development, and giving lectures.

The number of students I have taught so far has already exceeded 24,000 (as of July 25th) ! I feel this every time I teach many students, but I cannot forget the sense of pride I feel in education, so I will continue to provide education at Inflearn.
(* Among the students, there are those who passed the exams at Kakao Pay, Yanolja, and Woowa Brothers)

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

For these reasons , I hope that by sharing what I have worked hard to obtain, I can help those people live a slightly better life.

thank you!

        A four-year developer wanted to move to the next level and was studying cloud computing. Starting with AWS from scratch felt too overwhelming and difficult. I liked the approach of teaching only the essential concepts without unnecessary details, then immediately applying them through hands-on practice to engrave them in my mind. Also, after each hands-on exercise ended, you explained every single termination method step by step, so there was no worry about billing charges 😊😊
