Building a WordPress Service on AWS: Completing a Practical Infrastructure from VPC to HTTPS

I have created a 'Kubernetes Introduction/Practice' course that is easy for non-majors to understand and can be applied immediately in the field!

I have created an 'Introduction to Kafka' course that is easy for non-majors to understand and can be applied immediately in practice!

This is a practice-oriented course where you will learn how to manage and automate AWS infrastructure as code using Terraform. In this course, you will learn step-by-step, from the basic concepts of Terraform to the process of directly creating key AWS resources (EC2, VPC, Subnet, etc.). Additionally, you will conduct hands-on exercises to easily deploy infrastructure and verify results using a SaaS platform without the need for separate installations. Through the experience of directly creating and managing infrastructure in a real AWS environment—rather than just theory—you can develop infrastructure automation skills that can be applied immediately in the field.

I have created a course titled 'Introduction and Practice of Load Testing for Large-Scale Traffic Handling' that is easy for non-majors to understand and can be applied immediately in practice!

Master AWS networking completely! Learn VPC, subnet, routing, and security with a focus on practical application, and design secure and scalable cloud network architectures. Complete the core skills that every working engineer must know in a short period of time!

This is not just a lecture for memorizing commands. It is a practical introductory course designed to help you intuitively understand the "flow" of technology—why containers emerged and the principles behind how Docker creates and runs images. Even those new to Docker will be able to explain for themselves "why containers are a necessary technology" after taking this course.

It was created to solve the problem of “not knowing where or how to start with Kubernetes.” Based on hands-on experience gained from operating financial infrastructure, it is structured to help learners understand Kubernetes by following the actual process of building and operating it, rather than focusing on theory alone. Through a learning progression covering its relationship with Docker, YAML, Pods, Deployments, and Services, learners will internalize Kubernetes not as a “concept,” but as a “usable technology.”

This course provides a systematic learning experience, covering everything from basic JavaScript synchronous/asynchronous concepts to modern asynchronous processing methods like Promise and async/await, as well as practical HTTP communication.

Learn cloud infrastructure automation technology using AWS and Terraform, and practice efficient infrastructure management and deployment. Manage AWS resources as code through Terraform, and learn how to deploy consistent infrastructure across various environments.

Through this lecture, you can understand the security architecture of Naver Cloud and the expected operating costs.

If you want to work for a long time as a super developer who can handle the entire process of service development and operations alone, building a solid foundation in IT infrastructure knowledge is just as important as learning various programming languages!

For the sole purpose of passing the exam, we have summarized and organized the key contents of each exam area to prepare for the AWS (AWS Certified Solutions Architect-Associate) certification.

No more 'Question - Answer - Read-through' explanations! We explain all the knowledge related to how to solve AWS SAA certification exam questions!

This course focuses not simply on how to configure NGINX, but on solving the problems that arise in interviews and real-world work when you do not understand why these structures and configurations are necessary. Based on experience serving as an interviewer at Naver, Kakao, and Toss and evaluating countless candidates, the course explains, with hands-on practice, how to describe and use NGINX from the perspectives of performance, scalability, and operations. The core of this course is helping you develop a way of thinking that allows you to understand traffic flow and track down problems, rather than merely memorize configuration values.

This course is an introductory lecture prepared for those who are new to Terraform, an infrastructure automation tool. Instead of repeatedly performing manual configurations in cloud environments, you can learn how to easily and quickly build and manage infrastructure using code. It is specifically designed with easy explanations and hands-on exercises that even non-majors can follow, so that beginners who are encountering the concept of IaC for the first time can understand it.

I've created a cram course that will help you pass the AWS SAA-C03 (AWS Certified Solutions Architect - Associate) certification in just 2 weeks with only 163 questions!
