The document discusses the architecture of modular monoliths using Spring, emphasizing the benefits of a single project structure, straightforward infrastructure, and independent service deployment. It outlines a systematic approach to modularization, encapsulation, and context boundaries, supported by various references and resources. Additionally, it highlights that modular designs allow for better organization and specialized problem-solving capabilities.

7. SpringApplication application = new SpringApplicationBuilder()
.sources(MonolithsApplication.class)
.child(FirstServiceConfiguration.class)
.sibling(SecondServiceConfiguration.class)
.sibling(ThirdServiceConfiguration.class)
.build();
application.run(args);

21. ✔ 단일 프로젝트에 모든 코드가 모여있다
✔ 시스템 구조가 간결하고, 빠르게 구축할 수 있다
✔ 테스트 및 배포 파이프라인 구성이 간단하다
✔ 인프라스트럭처 구축와 운용이 간결하다

22. ✔ 시스템을 조직 구조에 맞게 더 적절히 정렬 할 수 있다
✔ 서비스를 독립적으로 배포 또는 확장 할 수 있다
✔ 서비스 장애가 시스템 전체 장애로 전파되지 않는다
✔ 문제 해결에 특화된 다양한 기술을 도입할 수 있다
