어떻게구축하시겠습니까?

필요할때수동으로… AWS Management Console AWS CLI(Command Line Interface)

조금더생산적인방법으로… Scripting language 사용 : AWS CLI 포함 Boto library 를사용하여 Python application 개발

AWS CloudFormation

AWS CloudFormation은 개발자와 시스템관리자가 관련 AWS 리소스 모음을 쉽게 생성및 관리하고, 이를 순서에 따라 예측 가능한방식으로 프로비저닝하고 업데이트할 수 있는간편한 방법을 제공합니다.

2010년 첫 출시

AWS CloudFormation

애플리케이션 실행에 필요한 AWS 리소스는물론 기타 관련 종속성 또는 런타임파라미터에 대해설명하는 템플릿

AWS CloudFormation

일반적으로 사용자는 AWS 서비스를프로비저닝해야 하는 순서나 종속성을

기억할 필요가 없습니다.

AWS CloudFormation

일단 배포한 다음에는 예측 가능한 방식으로AWS 리소스를 수정하거나 업데이트할 수있습니다. 즉, 소프트웨어의 버전 관리와

동일한 방식으로 AWS 인프라의 버전 관리가가능합니다.

AWS CloudFormation

CloudFormation이대신 처리합니다.

AWS CloudFormation

AWS CloudFormation에는 추가 요금이없으며 애플리케이션 실행에 필요한

AWS 리소스에 대해서만 요금을지불하면 됩니다
