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 is a course on developing microservice applications using the Spring Cloud suite from the Spring framework. You will learn how to use and configure Spring Cloud as a Cloud Native Application.

Through Zabbix, you will learn how to integrate with the in-house infrastructure environment (Windows, Linux, network, storage). Starting from the basic principles of Zabbix, we will teach you monitoring automation through Grafana and Slack integration.

"Enter the world of Cloud Infrastructure Automation!" Terraform, an infrastructure automation tool, is used to provision and manage resources in a cloud environment. Now, you too can define and automate your cloud infrastructure as code to quickly and consistently configure an infrastructure environment!

This 'Core Practical Linux' course is designed for those new to Linux, as well as those looking to enhance their practical Linux skills. It covers core basic Linux content and focuses only on essential and frequently used features from a backend developer's perspective.

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.

The ultimate goal of this course is to go beyond programming using IPC tools and to "develop the ability to appropriately select and design/implement IPC tools that fit software requirements."

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.

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.

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.

Building a Springboot Monitoring System (Prometheus + Grafana) | Teaching how to set up and utilize Building a Springboot Monitoring System (Prometheus + Grafana) from setup to application.

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.
