경량 프레임워크 마이크로서비스
레임워크와 잘 버무리면 요즘 마이크로서비스에 필요한 애플리케이션 배포/관리 기능은 대용
량 프레임워크보다 오히려 더 낫습니다.

상태 처리와 체인지로그 활용
경량 프레임워크의 기본 작동 모드는 이벤트 브로커에 저장된 체인지로그를 기반으로 내부 상
태를 사용하는 것입니다. 내부 상태를 이용하면 각 마이크로서비스가 배포 구성에 따라 획득한
리소스를 스스로 제어할 수 있습니다.
TIP
경량 애플리케이션은 각자 완전히 독립적으로 움직입니다. 필요에 따라 고성능 로컬 디스크에서 인스턴스를 실
행할 수도 있고, 속도는 느리지만 용량이 매우 큰 하드 디스크 드라이브에서 인스턴스를 실행할 수도 있습니다.
다양한 스토리지 엔진도 끼워넣을 수 있어서 모델과 쿼리 엔진이 다른 외부 상태 저장소를 이
용할 수 있습니다. 경량 프레임워크가 가진 모든 이점을 충분히 누리면서 그래프 데이터베이스

같은 옵션도 동시에 사용할 수 있습니다.
대용량 프레임워크의 체크포인트 모델과 달리, 경량 프레임워크는 내부 상태 저장소를 사용하
며 이벤트 브로커를 이용해서 체인지로그를 저장합니다. 체인지로그는 확장 및 장애 복구에 필
요한 보존성을 제공합니다.
