Note on Content Creation

• This course contains the use of artificial intelligence.

• I originally wrote the course scripts in Korean and then translated them into English myself. The voice you’ll hear is generated with text-to-speech, so it sounds clear and consistent throughout the lessons for a smooth and comfortable learning experience.

• It was hard work, but I was also excited to share this course with students from all around the world.

About the course

• Master AWS by building a complete cloud architecture from the ground up.

• In this fully hands-on course, you will start with nothing and finish with a complete architecture with networking, compute, storage, security, scaling, and hybrid connectivity.

• Unlike theory-heavy tutorials, this course focuses 90% on practical labs that mirror real-world deployment scenarios.

• You will not only learn how to use each AWS service, but also how these services connect and interact to form a fully functional cloud infrastructure.

• Step by step, you will deploy VPCs, launch web servers, secure your network, configure load balancers, set up databases, and implement auto scaling.

• You will also experience advanced architectures such as private networks, cross-VPC communication, and hybrid connectivity with on-premises systems.

• By the end of the course, you will have the confidence to design, build, and manage AWS environments that are reliable, scalable, and ready for real-world use.

• Whether you are a beginner or someone preparing for AWS certifications, this course gives you the practical foundation you need to succeed.

What You’ll Build

• A custom VPC with public and private subnets

• A public EC2 web server with LAMP stack

• Network security with Security Groups and NACLs

• Elastic IPs and Elastic Network Interfaces for flexible networking

• A shared file system using Amazon EFS

• Application Load Balancer with path-based routing and sticky sessions

• Private networking with Bastion Host and NAT Gateway

• A Multi-AZ RDS setup with read replicas and failover testing

• Auto Scaling groups with real scaling tests

• VPC Endpoints for private access to AWS services

• Cross-VPC communication using Peering and Transit Gateway

• A Hybrid network using Site-to-Site VPN with Libreswan
