Let's leverage AWS's key networking services to build everything from simple, basic networks to multi and hybrid networks, understand traffic flow in the architecture, and develop the skills and confidence to implement real cloud networks ourselves.

This is a hands-on introductory course for AWS cloud beginners that follows and learns basic AWS cloud network knowledge.

This is a course where you create a mini RPG 2D game to learn 2D development techniques, and then learn the process of converting the completed game into a network game by transitioning it to Netcode for GameObject. It covers various essential tilemap functions for 2D games, and is designed to naturally help you learn clean code writing techniques that adhere to SOLID principles. Additionally, this is a lecture that builds the foundation for network games using the updated Netcode API in the latest Unity 6 version.

The most difficult thing when malware is distributed is script obfuscation. Understand the obfuscation technique and analyze the malware executable file that is distributed after decrypting it.

I want to launch a side project as a real service and study Kubernetes, but managed services from AWS/GCP (EKS, GKE, etc.) are too expensive. On the other hand, running it only on a local computer makes it difficult to experience network configurations or actual deployment environments. We will utilize the "Always Free" tier of Oracle Cloud (OCI), which offers the most powerful free benefits among existing public clouds. By installing the lightweight yet powerful k3s, we will build a Linux server and Kubernetes environment capable of hosting actual services from scratch—all at zero cost. After taking this course, you will gain a general understanding of cloud networking and possess your own Kubernetes cluster infrastructure where you can deploy and operate your applications for free.

This course is Part 3 of the Full Stack lecture series, designed to help you solidly master the latest server technologies and Docker. The course is structured to enable you to practically incorporate Docker into your tech stack by meticulously testing Docker's various options, learning related technologies such as Linux that are necessary for understanding Docker, and building actual complex services.

Learn about the network multiplayer framework, also known as the other Unreal Engine. Learn the key concepts, inner workings, and optimization techniques you need to know when creating a network multiplayer game, then create a hack & slash type PvP battle game.

This course will help you understand the value of IoT and how it changes our lives and society. You will learn the basics of IoT device programming, IoT device connection technology, big data analysis, and automation. You will understand digital transformation and its impact on businesses and society.

You'll gain a very clear understanding of what diagnostic communication is in automotive SW roles, and what a diagnostic communication practitioner does and how! This lecture provides content specific enough for practitioners to immediately start work with actual spec documents.

This is Part 1 of a roadmap lecture that concisely organizes the essential computer science (CS knowledge) needed to excel in development and data, in a short period. This lecture has also been used as an in-house lecture at top domestic companies for several years. Based on 20 years of experience in actual practice, from system SW to web, app development, and data science, this lecture systematically yet easily organizes the essential core knowledge needed to excel in development and data.

We have gathered all the essential network theories that those planning to operate services in an AWS environment must know. Through this course, you can understand the principles of how AWS VPC (Virtual Private Cloud), composed of private networks using Private IPs, works and gain a detailed understanding of the roles of services such as ALB and NLB.

This training will help you understand the world-famous cloud, build your own cloud environment, and strengthen your ability to use it easily.
