AWS アーキテクチャを最も簡単に学ぶ — 基本CSから実務ベースのAWSハンズオン実習

Docker, a technology stack used by over 20 million developers worldwide! We'll study Docker and container concepts, which have become essential technology stacks for countless developers, by following the official documentation! I think you might have been intimidated before even starting when looking at the thick Docker books among the technical documents available in the market. This course is structured with a solid curriculum focused on hands-on practice, highlighting core content based on Docker's official documentation. I promise that this course will help you quickly apply Docker in real-world scenarios! After completing the course, you'll be able to use Docker in various practical ways!

I've created an introductory CI/CD course that's easy for non-majors to grasp and immediately applicable in practice!

🎉2025 Lecture Renewal with New Videos🎉 We will explore the detailed functions and options of AWS's most basic and essential key services. By gradually implementing cloud architecture using these services, we aim to foster an understanding of infrastructure structure and operational principles, along with the capability and confidence to build cloud infrastructure directly.

This course is a practical-focused learning program for JWT-based token authentication and security enhancement techniques that are essential in modern web service environments. Using Spring Boot 3, Spring Security 6, and React, you'll implement secure login systems and cover comprehensive security practices including XSS·CSRF countermeasures, HTTPS implementation, token reissuance and revocation strategies, and secure secret key management. Additionally, you'll practice real service-level environment configuration through AWS build·deployment and performance optimization using Redis, and the complete project source code provided in the course can be directly applied to real-world work.

It explains almost everything surrounding the cloud in an easy-to-understand manner. If you listen to it before the actual practice, you will be able to understand development or infrastructure cloud well.

This course covers core computer science knowledge such as networking, multi-threading, and operating systems, and teaches MMORPG technology by building a game server from the ground up. It provides a comprehensive overview of the knowledge that a new server programmer should know, building a foundation that allows them to adapt to any project without feeling overwhelmed.

It is configured to allow you to learn programming languages (Python, Terraform) for the cloud. You can directly create and apply simple yet tedious repetitive tasks, track when and how you deployed, and implement your company's unique policies that specific solutions cannot address. Specifically, we will apply a security architecture using Terraform, the most popular IaC (Infrastructure as Code) application, and also proceed with creating an ultra-simple dashboard using Python!

Starting with java.io, you can learn how to develop high-performance input/output systems based on NIO and NIO.2. Most importantly, the moment you master file I/O, we'll enable you to master high-performance server development as a bonus!

You can quickly experience the process of deploying an example e-commerce service to AWS and continuously improving it into a robust and efficient environment.

You can learn about IAM, the foundation of AWS Zero Trust, from the basics to the details. This will help you understand what parts are actually vulnerable and where you need to pay more attention.

"AWS deployment tutorials - have you ever followed them without knowing 'why' you're doing it?" If you've launched services by following the countless deployment tutorials on the internet but are only performing repetitive tasks, the next step of designing entire systems might feel overwhelming. We don't just learn how to use AWS, but study the CS (Computer Science) principles that form the foundation of cloud services, including VPC, NAT, load balancing, and MSA. Upon completing the course, you'll be able to answer the clear 'Why' behind each action you perform in the cloud. You'll no longer be a junior developer performing simple repetitive tasks, but will take your first step toward becoming a senior architect who designs fault-tolerant and scalable systems.

Linux is an operating system widely used on various platforms worldwide, including servers, the cloud, and IoT devices. Through this course, you can enhance your competitiveness in the IT field based on a deep understanding of Linux. Furthermore, by acquiring expertise in open-source technology, you can prepare for the future technological landscape and stand out in a high-demand job market.

This course is for those who want to develop packet analysis programs like Wireshark and various network solutions using the Npcap library.

This lecture introduces serverless systems through AWS Lambda, and creates an image processing end system with OpenCV, an image processing library, and expands it with an API.

This is a course where you study core computer science knowledge such as networking/multithreading/operating systems and learn MMORPG technology by building a game server from scratch.

We will complete one full cycle of a backend service using Spring Boot, MySQL, Docker, AWS EC2, and RDS. Gain a sense of accomplishment through application deployment, and cover issues server developers face in real-world API development and their solutions.

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.

This course covers the essential knowledge that every 0.5 to 3-year C# application developer should have.

We foster capabilities to prepare for future technological changes by learning from the basics related technologies that are at the core of 4th Industrial Revolution technologies, such as ICBM (IoT, Cloud, Big Data, ML), autonomous vehicles, and the metaverse.

This course covers how to actually publish the websites I've created to the world. From basic hosting using Dothome to hosting on git and cloud deployment through AWS, it's structured so you can easily follow along while experiencing hosting step by step. Rather than just stopping at writing code, you can build confidence as a web developer through various hosting experiences and actually operate real services.

CS knowledge lectures on design patterns, networks, operating systems, databases, etc. from the author of the #1 book in Korea, "CS Major Knowledge Notes for Interviews"! Covers all the concepts needed for CS interviews and the latest past questions!
