CloudNet@ - AWS Networking Fundamentals

This course covers the basics of Amazon EKS, an AWS-managed Kubernetes service, designed for beginner Amazon EKS users.

This is an extended Amazon EKS course covering a wide range of topics that Amazon EKS users should definitely know.

Understand the security configurations of major AWS services through architecture diagrams, and gain a practical understanding of how they work by verifying them firsthand through hands-on exercises and security scenarios.

This is the "Network Model" episode, the first step of the basic network lecture series that you can learn even if you don't know the first thing about networks.

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

Learning Network Basics through Stories, You Can't Learn Network Basics Easier Than This. It's a really easy network basics lecture. And if you take all the lectures, you'll have a basic understanding of networks!

This course is designed to guide those who have completed the "Mastering Core Network Theory through Memorization: Basic Course" to understand more advanced theories. It covers deeper concepts such as NAT technology, which is the operating principle of internet routers, as well as load balancing system principles and VPN technology principles. The goal of this lecture is also to finish by "memorizing" it all! You can do it!

This is Part 1 of a roadmap course that neatly organizes, in a short amount of time, the essential computer science (CS) knowledge you need to excel at development and data. This course has also been used for years as an in-house course at top companies in Korea. Based on 20 years of experience in the field, ranging from systems software to web and app development and data science, this course systematically and thoroughly covers the core concepts you need to excel at development and data—while keeping them easy to understand.

Directly assess various threats that may arise in AWS security environments, and expand your security operations capabilities by experiencing monitoring, detection, and response processes through hands-on exercises and security scenarios.

We will explore the detailed features and options of AWS's most fundamental and core services, and by implementing cloud architecture step-by-step using these services, we will understand the structure and operating principles of infrastructure while building both the capability and confidence to directly construct cloud infrastructure.

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!

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

This course is designed to help learners build solid AWS cloud engineering and architecture skills through hands-on projects and practical demonstrations. Students will learn how to build secure AWS environments, manage scalable computing infrastructure using EC2 and Auto Scaling, configure networking via VPC and Load Balancers, and implement cloud-native storage and database solutions using S3, Aurora, and MySQL. Throughout the course, I will guide students step-by-step using hands-on labs, architectural explanations, and real-world deployment scenarios commonly used in modern cloud environments. I focus on simplifying complex AWS concepts into easy-to-understand lessons while helping students avoid common mistakes made during cloud deployment, security configuration, and infrastructure scaling. By the end of this course, students will not only gain the confidence to design secure, scalable, and cost-effective solutions on AWS but will also be prepared for the AWS Solutions Architect Associate certification exam.

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.

⚓ Kubernetes CKAD Certification! 🙇‍♀️Are you still hesitating? 🚢Board the Ilpro-ho! We will guide you through the optimal route.

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.

Creating a simple Omok game using Unity and a C# server

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.

How do the sites we access every day work? Before we start studying data in earnest, let's take some time to learn about servers and the Internet, which are the background knowledge of IT.

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.
