Core Network Theory to Finish by Memorizing - Application
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!
I have created a course where anyone can build their own service!
Hello, students. This is Hosing Choi, the "Leisurely Developer."
I have refined and created the Vibe Coding lecture until I reached the conclusion that it was sufficient by my own standards. However, now that it's finished, it seems that it has effectively become an AWS lecture rather than a Vibe Coding lecture.
If you want to create your own service based on AWS, I believe this course will be sufficiently helpful. In fact, the nullnull.co.kr service I created is being operated with the following structure.
The AWS Amplify frontend is connected to GitHub for automated deployment, and security is ensured by combining S3 bucket storage and ALB through CloudFront with WAF attached. Lecture videos are converted for streaming using the MediaConvert service, uploaded to a Private S3 bucket, and provided as a streaming service via the Pre-signed URL method. The backend runs on an EC2 instance based on 2 vCPUs + 2GB RAM. Finally, the PostgreSQL DB is being served through RDS.
You can think of this course as covering everything in this diagram except for MediaConvert. I can confidently say that if you truly need your own service or a production-grade portfolio that works properly, you should not miss this course!
I hope this post serves as helpful information rather than just an advertisement, and I will continue to greet you with great lectures in the future. Thank you always. 😄
