DevOps Interview Preparation: Master your interview preparation for Cloud, CI/CD, Infrastructure as Code, Monitoring, Linux, Docker, and Kubernetes.

This is a practice-oriented course where you will learn how to manage and automate AWS infrastructure as code using Terraform. In this course, you will learn step-by-step, from the basic concepts of Terraform to the process of directly creating key AWS resources (EC2, VPC, Subnet, etc.). Additionally, you will conduct hands-on exercises to easily deploy infrastructure and verify results using a SaaS platform without the need for separate installations. Through the experience of directly creating and managing infrastructure in a real AWS environment—rather than just theory—you can develop infrastructure automation skills that can be applied immediately in the field.

This is a 'practice-oriented course' where you will build and deploy infrastructure for a system tailored to the appropriate environment.

Running MongoDB on Kubernetes is different from simply putting it in a container. There are many things you can only learn by dealing with storage, networking, permissions, and high availability firsthand. This course covers the entire process of configuring and operating MongoDB using the PSMDB (Percona Server for MongoDB) Operator in an AWS EKS environment. The goal is to directly build a production-ready configuration, from cluster setup to Replica Set configuration, backup, and monitoring.

"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.

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.

It was created to solve the "overwhelming problem of not knowing where or how to start with Kubernetes." Based on hands-on experience operating financial infrastructure, it is designed to help you understand the actual build and operation flow rather than just simple theory. Through a learning process that covers the relationship with Docker, YAML, Pods, Deployments, and Services, learners will master Kubernetes not just as a "concept," but as a "usable skill."

This book contains all the know-how of a person who majored in physical education and started studying development at the age of 29, becoming a top-tier developer at a company with a salary of 40 million won at the age of 30, 60 million won at the age of 31, and more than x million won at the age of 32!

I've created a course on 'How to Write a Developer Resume/Portfolio' that can help even non-majors pass the document screening stage!

What should you do if you want to appeal to your "development capabilities" rather than just your "specs" during the developer document screening process? This lecture focuses on teaching you how to write a resume that can increase the pass rate for developers who have excellent "development capabilities" but struggle to get interview opportunities. We will show you how to document your "development capabilities" in your resume, including SI company experience, academy courses, and personal portfolios.

This is a lecture on subnetting, which is necessary when creating or reading network diagrams.

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 the fundamentals of the web, networks, and HTTP that every developer should know, in a code-based, real-world, data-driven way.

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

AWS CLF (Certified Cloud Practitioner) is an introductory course that allows you to build basic knowledge of the cloud. By increasing your understanding of AWS cloud technology and services through this certification, you can move on to more specialized certifications in the future and build the basic capabilities necessary for cloud-based development and operations.

You can learn UIkit, a representative CSS Framework along with Bootstrap, from the basics to advanced usage. A well-made personal portfolio website is essential for getting a job as a publisher. In order to show your portfolio results in a sophisticated way on your personal portfolio website, you can learn the detailed usage of UIkit components such as Slideshow, Slider, Lightbox, Full Screen Modal, Filter, and publishing skills and know-how to use them in actual production.

From HTTP basics to data requests, real-time communication, security, and performance optimization, learn the network knowledge web developers must know.

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.
