DevOps 어려운 이유?

개발, 시스템과 아키텍처에 대한 깊은 이해 필요

높은 구축 비용

유지보수 문제

개발자의 저항감

• 업무 강도 향상

• 문서 vs. test

그래도 DevOps

Legacy

• 대규모 업데이트의 영향 최소화를위해 새벽에 배포

• 버그 추적과 전체 롤백의 어려움

• 문제점 파악 및 해결에 따른 부서간 반목

DevOps

• 효율적인 테스트 및 디버깅을 위해업무시간중 배포

• 문제 발생시 바로 롤백, 수정 및 재배포

• 팀원간 원할한 소통과 책임 분배

• 빠른 개발 및 적용

개발과운영의간극

개발• 아주 빠른 템포

• 문제가 생기면 밀고 새로..

• 새로운 환경에 익숙함

운영• 느린 템포

• 디비/앱은 증분 업데이트로

- 문제시 롤백!

• 권한 관리가 매우 중요
