74 효율적인 코드형 인프라의 원칙, 패턴, 실행법

코드형 인프라IaC는 소프트웨어 시스템에서 사용되는 증명된 코딩 기술을 인프라로 확장하는 접근 방식이다.1 IaC는 핵심 데브옵스 실행법 중 하나로, IaC를 사용하면 특히 클라우드에서 규모가 큰 인프라 제공과 소프트웨어 구동을 빠르고 안정적으로 실행할 수 있다.
¦ 핵심 원칙 ¦
IaC 핵심 원칙 두 가지는 멱등성과 불변 인프라immutable infrastructure다.
• 멱등성은 IaC를 몇 번 수행하든지 최초 상태와 최종 상태는 항상 동일하다는 의미다. 인프라 프로비저닝을 단순화하고 불일치 결과 발생 확률을 줄인다. 멱등성은 테라폼(Terraform)2과 같은 선언적 언어(declarative language)와 상태 저장 도구를 사용해서 달성할 수 있다. 테라폼을 사용하여 원하는 최종 상태를 정의하면 테라폼의 잡이 달성해야 할 최종 상태가 된다. 최종 상태가 되지 않는다면 실패한다.
• 불변 인프라는 기존 인프라를 변경하기보다는 새로운 인프라로 대체한다는 의미다. 새로운 인프라를 매번 프로비저닝해서 구성을 재현할 수 있고, 시간에 따른 드리프트를 피할 수 있다.
