How to Build a Simple, Fast, and Robust Server Environment with AWS

Introduction to the lecture

• It contains only the core of the process of building a server in a cloud environment directly at a startup and improving it through trial and error .
• By going through a similar process to the lecture in the field, we were ultimately able to reduce costs by more than 20 percent and also significantly reduce operational overhead .
• In this lecture, we will practice using a virtual e-commerce service called Goopang .
  (You just need to download a project that has been pre-made with Spring Boot and distributed to GitHub.)
• With just this course, you will gain experience using more than 15 AWS services !
• You can experience first-hand the process of introducing AWS services one by one and gradually improving the Gupang service.
• This may be the answer for those who are concerned about adopting Kubernetes due to its learning curve or operational overhead .
• You may want to gain some experience with container orchestration before learning Kubernetes.
• To help you understand , I used many images like the ones below.

Lecture target

• Developers or students who want to gain experience in stable deployment and operation in a cloud environment
  
• Developers who want to reduce cloud operating costs
• Students who want to experience MSA (microservice architecture) and container orchestration
• A developer who operates on AWS but feels anxious every time he goes on vacation
• Developers who are wondering how to start introducing services other than EC2, S3, and RDS
• A developer who is solely responsible for cloud and backend development.
  

Course Objectives

• Running a cloud native environment locally
• Migrating from Monolithic Architecture to MSA
• Introducing Container Orchestration in an MSA Environment
• How to handle basic services for building services on AWS
• The lecture aims to improve the service structure and ultimately achieve maximum availability and scalability with minimal operational overhead and cost .
• The gif below is a diagram architecture that we will create while improving the Gupang service through practice.
  The diagrams may seem difficult now, but you will understand them all after taking the class.

Learning Materials

Server Application Project - The server application required for the practice is a pre-built project using Spring Boot that has been distributed to GitHub.
It also includes code and content for cloning the project to be used during the training, so even if you are not familiar with Spring Boot, it is not a problem.

PPT - The first video of the lecture section consists of the overall theoretical content of the section, and the last video consists of the summary content. The PPT of each lecture is uploaded as a PDF file, so please refer to it if you need it.

Expected Questions

• Q. Can I take the course even if I don’t know Spring Boot ?
• A. Yes. You will not be required to write any code in the lecture.
  All you have to do is download the Spring Boot project I've created in advance and adapt it to your needs.
  To aid understanding, simple code and function reviews are included in the lecture.
  
  
• Q. Can this course replace Kubernetes ?
• A. No. It is not a complete replacement, but you can experience operating a container orchestration environment like Kubernetes .
  And my personal opinion is that it has a lower learning curve than Kubernetes, can be simpler to operate, and has the advantage of lower cost .
  
  
• Q. So, would it be better to learn Kubernetes rather than taking this course?
• A. In practice, if the requirement is to introduce Kubernetes, then it may be possible.
  However , depending on the environment, Kubernetes may actually increase operational overhead .
  The environment ultimately built in this course will be of great help to aspiring developers who want to gain experience in an early stage startup or production environment with minimal operational overhead and a relatively low learning curve and cost.
  
  
• Q. Will taking this course help me learn Kubernetes ?
• A. Kubernetes is a container orchestration tool .
  In this course, you will use AWS's container orchestration service and perform basic operations .
  Therefore , I think it will be very helpful to learn Kubernetes after taking the course .
  
  

Things to note before taking the class

• Small costs may inevitably arise during the training!
• To save money, we recommend that you sign up for a new account to use the AWS Free Tier whenever possible.
• Although we use Spring Boot as a server application in the course, you won't be writing any code , so it's okay if you don't know Spring Boot .
• It would be nice to have some basic cloud service concepts , but it's not necessary.
• It would be nice to have basic network communication concepts (REST API, etc.), but it is not necessary.
• The lecture omitted basic membership registration and download guides .

Practice environment

• In the training, we tried to proceed in a way that was as unaffected by the OS or environment as possible, but please keep this in mind.
