AWS Lambda + OpenCV

I have created an introductory CI/CD course that is easy to understand even for non-majors and can be applied immediately in practice!

I have created an introductory AWS course that is easy to understand even for non-majors and can be applied immediately in practice!

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.

A former AWS employee explains what a well-architected framework looks like within AWS. We will cover how to build an architecture that starts small and scales to handle massive traffic. You will learn various AWS services through a hands-on approach, solving the diverse challenges encountered when designing architectures for high availability and security.

We will inform you about all the security aspects of migration using MySQL and direct operation of DB Server.

This class covers the basics of using AWS (Amazon Web Services), a cloud service, and S3, which provides storage space for files.

Build a WordPress 3-tier infrastructure from VPC to HTTPS in 8 steps using YAML templates instead of console clicks. Starting with an empty AWS account, this hands-on course builds security groups, RDS, EC2, ALB, and Route53 layer by layer, culminating in a reusable set of templates. Develop practical IaC skills, from template syntax and passing values between stacks to safe deletion order.

I’ve created a cram course that can help you pass the AWS SAA-C03 (AWS Certified Solutions Architect - Associate) certification in just two weeks with exactly 163 questions!

You can quickly experience the process of deploying a sample e-commerce service to AWS and continuously improving it into a robust and efficient environment.

Let's look into how to deploy Abyss for non-majors!

You can learn about IAM, the foundation of AWS Zero Trust, from the most basic elements to the most detailed specifics. Through this, you can learn which parts may actually be vulnerable and where you need to pay more attention.

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.

This course covers how to actually publish the websites I've created to the world. From basic hosting using Dothome to hosting on git and cloud deployment through AWS, it's structured so you can easily follow along while experiencing hosting step by step. Rather than just stopping at writing code, you can build confidence as a web developer through various hosting experiences and actually operate real services.

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.

A 75-minute session for those who have built REST APIs with Spring but are unfamiliar with AWS serverless. We’ll clarify what Lambda, SQS, DLQ, S3, and DynamoDB each are and aren’t responsible for, and directly observe how messages are redelivered and isolated in a DLQ. Hands-on exercises are conducted locally without an AWS account.

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.

After learning SQL tuning, automate recurring tuning tasks. This hands-on project connects everything from collecting MySQL queries to AI diagnosis, empirical validation, handoff to the person in charge, and tracking recurrence.

A solo IT startup founder and solo entrepreneur's experience distilled into an honest, straightforward, intuitive, and deep React + Spring Boot course (Docker, AWS, GitHub Actions) I just unified everything into this one course.

This is a full-stack restaurant map tutorial that allows you to learn everything from front-end, back-end, Kakao Map API usage, and deployment all at once while creating a restaurant map of your favorite YouTuber.

‘Where and how should I store files that look like images? Should I store them in a database? Or on a server hard drive? How can I reduce server load? How can I quickly load many images without stuttering? AWS S3? CDN?! I just want to store and load images, so why are there so many elements? What role do each of these elements play, and how should they be combined?’ I will teach you all the necessary elements related to image files, from start to finish, as a full stack :)
