마이크로서비스 워크플로 구축
전형적인 안티패턴입니다. 그렇게 만들면 결국 오케스트레이터와 워커 서비스 간의 워크플로
비즈니스 로직이 여기저기 흩어져 캡슐화가 잘 안 되고 경계 콘텍스트가 잘못 정의돼서 워크플
로 서비스의 소유권을 여러 팀으로 확장시키기가 어려워집니다. 오케스트레이터는 워커 서비
스에게 완전히 책임을 위임하고 자신이 수행하는 비즈니스 로직은 최소화하는 게 좋습니다.

오케스트레이션 워크플로 모니터링
구체화 상태를 쿼리하면 오케스트레이션 워크플로를 가시화할 수 있어 특정 이벤트의 진행 상
황 및 워크플로에서 발생 가능한 이슈를 파악하기 쉽습니다. 또 오케스트레이터 레벨에서 모니
터링, 로깅을 구현하면 워크플로 장애를 유발하는 이벤트를 탐지할 수 있습니다.

은 둘 이상의 마이크로서비스에 걸쳐있는 트랜잭션을 말합니다.
마이크로서비스는 각자 트랜잭션에서 자신의 분량을 처리하되 트랜잭션이 중단되어 되돌아갈
경우 처리한 내용을 되돌립니다. 이러한 이행

로직은 반드시 동일한 마이크
로서비스 안에 두어야 합니다. 그래야 롤백을 할 수 없을 경우에도 새 트랜잭션이 시작되지 못
하게 할 수 있고 관리 목적으로도 필요하기 때문입니다.
