Basic Linux (Ubuntu) knowledge for developers

The Practical Guide covers overall infrastructure as well as shell scripting. We structured it focusing mainly on practical scenarios and troubleshooting (problem resolution) that is frequently handled in practice!

This course is Part 3 of the Full-Stack course series, designed to help you thoroughly master the latest server technologies and Docker. To enable you to genuinely incorporate Docker into your tech stack, the course meticulously tests Docker’s various options, covers related technologies such as Linux that you need to understand for Docker, and is structured so that you can even build complex real-world services.

This lecture will teach you the basic commands required for performance analysis of Linux servers, how to use the tcpdump command to solve network problems, and troubleshooting methods based on cases. Through this lecture, you will be able to solve various performance problems that occur on Linux servers.

I have created a 'Linux for Beginners' course that is easy for non-majors to understand and can be applied in practice immediately!

This is a 'Practical Linux Troubleshooting Course' where you analyze and solve problems together with generative AI, based on a Docker practice environment that reproduces 5 representative failures that occur in actual Linux operating environments. Even those who were overwhelmed about where to start examining problems can learn the problem-solving approach and thought process of field engineers through AI guidance.

If you study the main concepts of Linux, you can handle Linux more easily and more powerfully. I hope you build a solid foundation from the beginning!! :D

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 covers how to use Linux. The part that beginners find particularly difficult is how to control the computer using commands. This course covers the most common rules that beginners need to use commands.

The curriculum was created with commands that actual developers use. It does not cover complex concepts related to OS installation or management. You can quickly learn the basics of Linux usage in 2 hours.

In this course, you will learn how to have a free Linux server worth 20,000 won per month, how to use it, and how to utilize it.
