Microservice Application (MSA) Development with Spring Cloud
This is a course on developing microservice applications using the Spring Cloud suite from the Spring framework. You will learn how to use and configure Spring Cloud as a Cloud Native Application.
Build a cloud native architecture, Take on the challenge of developing microservice apps! 🚧
In IT systems, numerous technologies emerge and disappear every year. It takes a long time for newly released concepts, technologies, and methodologies to become established as stable systems through numerous references.
1960s~1980s
The 1960s to 1980s were the mainframe era, when hardware was the center. It was a time when services were built according to hardware specifications or characteristics rather than software, and because the hardware and systems themselves were quite expensive, it was quite difficult to modify or change the functions of the service. In this period, called Fragile, changing a system once it was built was not an easy task, and it required a lot of money and time.
1990s~2000s
The 1990s and 2000s were a time when the keyword was distribution. This period was called Robust and Distributed. Thanks to the system being stabilized/distributed, it was possible to build a system that could maintain stability and performance even when there was a certain degree of uncertainty or change in the service.
From 2010 to present
Since 2010, the system has been built with Resilient, Anti-Fragile, which is the opposite of Fragile, and Cloud Native. Virtualization technology has been introduced, and the IT environment and system of the company have been moved to the cloud, and scalability and stability have been further strengthened. Even if there are continuous improvements and changes from customers, the systems have been built to be processed quickly and operated flexibly.
Currently
Cloud technology is considered essential to the IT environment. Building IT systems in this Cloud environment can be called Cloud Native Architecture, and applications that run in the Cloud environment can be called Cloud Native Applications.
Suitable for cloud environment Why IT system construction is necessary.
CNCF (Cloud Native Computing Foundation), a Linux-affiliated organization, has mentioned the following four key components of Cloud Native Applications:
• CI/CD • DevOps • Microservices • Containers
Among these, Microservice is the core of Cloud Native Application and implements the service logic of the business domain. Microservice Architecture is a development method that is different from the monolithic method that deploys all components such as Front-end, Back-end, and Database in a single system environment. It refers to an architecture that develops and operates services by separating them by the well-divided boundaries that the application constitutes. For applications developed based on Microservice Architecture, Java, Spring Framework, and Spring Cloud can be used.
Spring Cloud is a development tool and development platform that provides the development environment and services required to develop distributed system configurations and applications, as well as development and configuration-related patterns, to enable rapid development of microservice applications for Cloud Native Architecture.
It provides basic boilerplate patterns to easily use technologies such as configuration management, service discovery, circuit breakers, intelligent routing, micro-proxy, control bus, one-time token, global locking, leadership election, distribution, etc. for microservice applications, and the developed applications and services maintain excellent compatibility so that they can work well in any distributed environment including the developer's local environment's laptop, bare metal data center, and management platform such as Cloud Foundry.
Objectives of this lecture
What is our ultimate goal ?
Using Spring Boot + Spring Cloud App designed with microservice architecture It's about designing and developing.
In this lecture, you will learn how to develop a Microservice application with Spring Cloud's products (subprojects) and how to build an operating environment. You will also learn how to configure the Gateway, Service Mesh, and Runtime that make up the Microservice Architecture, and the process of building and deploying for operation.
Those who take this course will be able to understand the basic Microservice Architecture and develop Spring Boot and Spring Cloud applications using IntelliJ, an integrated development environment for Java. They will also be able to practice deploying and operating them in local environments and container virtualization.
You can check out the practical examples used in the lecture below.

저는 IT 엔지니어입니다. 언젠가 직업란에 "회사원?", "개발자?", "강사?" 어떤 단어를 선택해야 할 지 고민이 되었던 때가 있었습니다. 그러다가, IT 엔지니어라는 표현이 제가 잘 어울리는 직업명이라는 생각이 들어 지금까지도 직업란에는 "IT 엔지니어"라고 적고 있습니다.
직업이라는 것은 자신의 일을 나타내는 것이고, 일이라는 것은 재미있고, 도움이 되는 일이면 좋겠다는 생각을 가지고 있습니다. 누구나 다 원하는대로 일을 하며 살수는 없지만, 저는 제가 하는 있는 이 일을 좋아하는 있고, 잘하고 싶어하는 사람입니다. 개발자로써, 강사로써, 컨설턴트로써의 역할을 해 오면서, 매번 새롭게 출시되고 변화하는 IT 신기술을 따라가기에 급급하지만, 그래도, 남들보다 조금이라도 먼저 접하고, 전파하고, 사용하고 싶은 사람 중 한명입니다.
최근 관심을 가지고 있는 분야는 온라인 교육 컨설팅입니다. 그리고 관심있는 기술은 Cloud Native Architecture, Blockchain, Machine Learning, Kafka, Kuberbetes 등입니다. 이러한 기술은 실제로 강의도 하고 있고 업무에 적용해서 사용도 하고 있습니다. 하지만, 워낙 방대한 주제이다 보니, 아직까지도 계속 공부하고 있습니다.
머리속에 가지고 있는 것은 진정한 지식이 아니라고 합니다. 저는 제가 가진 지식과 경험을 다양한 방벙을 통해 공유하려 합니다. 그리고, 새로운 분야, 새로운 기술에 계속 도전하고 있는 IT 엔지니어가 될 것입니다.
강사님 좋은 강의를 만들어 주셔서 감사합니다.
이 강의를 듣기 전까지 클라우드, 마이크로 서비스 등등 관련 책도 보고 얘기는 수도없이 많이 들었고, 만들어도 보았지만, 단편적인 지식들이 머릿속에서 뒤죽박죽이었답니다.
이 강의를 들을수록 머릿속이 깔끔하게 정리되는 느낌입니다. 아직 30%밖에 못들었지만, 계속 다음이 궁금해져 새벽까지 듣곤 합니다.
강의 구성은 챕터별로 왜? 어떻게? 무엇을 해야할지 처음에 명확하게 설명을 해 주신후 실제 코드로 구현해 주십니다.
필요한 엑기스만 뽑아서 해 주시고, 동영상 길이도 적당합니다. 구현 후에도 의도적으로 조금씩 수정을 해 주시면서 중요한 부분을 반복할 수 있도록 유도 해 주시네요.
아직 30% 밖에 못 들었지만 이 강의 후속으로
처음에 강사님이 그리셨던 그림대로 CI/CD, Cluster(쿠버네티스), 모니터링까지 준비해 주시길 간곡히 부탁드립니다. 감사합니다.
정말 찬사를 보내고 싶은 명강의입니다.
저는 신입 개발자로 사수없이 혼자서 MSA 구축하라는 업무지시 받고나서, 진짜 단순하고 작은 문제 하나에서도 2-3일씩 헤매느라 진도가 매우 느렸습니다.
그런데 이 강의 하나로, 제가 고민하던 문제 30개, 50개 이상을 단번에 치고 나갈 수 있었습니다.
강사님께 정말 감사의 말씀을 드리고 싶네요. 제 입장에선 100만원 이상의 값어치를 했습니다.
스프링과 도커 컨테이너 기반 마이크로 서비스에 대한 전반적인 내용을 체험 할 수 있게 해주는 알찬 강의 입니다.
시중에 판매 되고 있는 스프링 마이크로 서비스 관련 책들을 보는것보다 훨씬 더 유익한 강의 라고 생각 됩니다.
AWS , GCP, AZURE 와 같은 클라우드에 private docker repository 구축 및 사용과 쿠버네티스 강의도 있었으면 하는 바램 입니다.
좋은 강의 만들어 주셔서 감사합니다.
