Source - https://www.openmaru.io/?p=3228 쿠버네티스를 이해하기 위해서 반드시 알아야 하는 개념이 불변의 인프라스트럭처 입니다. 불변과 가변의 인프라스트럭처에서 서버 운영 방법을 비교하여 개념과 장점을 설명 드립니다. 이제 IT 환경이 왜 머신 중심에서 애플리케이션 중심으로 전환되고 있는지에 대해서 살펴보겠습니다. 불변의 인프라는 고급 도자기 찻잔과 비유 될 수 있습니다. 일회용 종이컵은 한번 쓰면 버리고, 구매하는데도 큰 부담이 없습니다. 하지만 고급 도자기 찻잔은 어떨까요?애지중지 관리하며 깨지면 모든 것이 끝나게 됩니다.

• 컨테이너화는 데이터 센터를 머신 중심에서 애플리케이션 중심으로 전환 • 개발자와 운영팀에게 서버와 운영 환경에 대한 세부 사항을 추상화 • 운영 중인 애플리케이션과 개발자에 미치는 영향을 최소화하면서 새로운 하드웨어 또는 운영 환경을 업그레이드하여 인프라팀에게 유연성을 제공 • 서버의 CPU와 메모리 정보 뿐만 아니라 애플리케이션과 관련한 매트릭을 연결하여 오토 스케일링 머신 중심에서 애플리케이션 중심 인프라로 변화 Machine Centric Infrastructure Application Centric Infrastructure
운영자님. 아직도 서버를 애지중지 키우시고 계신 가요?
