"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.

Understanding the 'Why' of deployment workflows: Beyond simply using the AWS console, understanding the fundamental CS principles and design intentions behind all infrastructure actions performed in the cloud, such as VPC, NAT gateways, load balancing, etc.
Design highly fault-tolerant infrastructure: Develop the capability to directly build systems that operate without interruption during failures and are securely isolated from external threats by utilizing **AZ separation, routing table rules, and two-tier firewalls (SG/NACL)**.
We establish a foundation for service expansion: Recognizing the limitations of monolithic architecture, we can proactively design scalable system structures that prepare for explosive traffic growth through load balancing, auto scaling, and CDN caching strategies.
Gain confidence in technical interviews and architecture reviews: Acquire practical knowledge to confidently answer senior-level system design questions such as MSA, RDBMS/NoSQL strategies, Subnetting, etc., based on clear CS knowledge and design intent.
Who is this course right for?
A junior developer who only repeated "deployment tutorials": Someone who knows how to use AWS but lacks understanding of the CS principles behind each configuration and how to handle failure situations, making the next steps feel overwhelming.
Developers contemplating the next step in their implementation skills: Those who want to go beyond simple coding and learn how to view the entire system from network, security, and scalability perspectives to design stable architecture.
For those who want to break down the boundaries between infrastructure and applications: Those who want to integrate knowledge of front/backend development and infrastructure operations in cloud environments to build comprehensive problem-solving capabilities.
Those who want to demonstrate cloud capabilities in technical interviews (system design).
