+# IaC를 이용한 인프라 구성 / 자동 배포 / 배포 로그 수집
+## CloudFormation 인프라 구성 / CodeDeploy 자동 배포 / CloudWatch 로그 수집
+## 전제사항
+* CloudFormation을 사용할 수 있는 IAM 계정 존재
+* CodeDeploy, CloudWatch Agent 설치된 AMI
+    * AMI 없이 UserData로 설치 가능
+* 빌드 파일을 실행하기 위한 요소(Node or Java)가 설치된 AMI 존재
+    * AMI 없이 UserData로 설치 가능
+* 프로젝트에 CodeDeploy 스펙을 정의한 appspec.yml 파일 존재
+
+## 자동 배포 진행 과정
+
+1. CloudFormation으로 LoadBalancer, Autoscaling Group, CodeDeploy 등 인프라 구성
+2. 배포하고자 하는 프로젝트 빌드 파일을 S3로 전송
+3. CodeDeploy를 사용하여 빌드된 프로젝트 파일 배포
+

+
+## 자동 배포 진행 과정
+
+1. CloudFormation으로 LoadBalancer, Autoscaling Group, CodeDeploy 등 인프라 구성
+2. 배포하고자 하는 프로젝트 빌드 파일을 S3로 전송
+3. CodeDeploy를 사용하여 빌드된 프로젝트 파일 배포

+## 자동 배포 진행 과정
+

+2. 배포하고자 하는 프로젝트 빌드 파일을 S3로 전송
+3. CodeDeploy를 사용하여 빌드된 프로젝트 파일 배포

+* 프로젝트에 CodeDeploy 스펙을 정의한 appspec.yml 파일 존재
+
+## 자동 배포 진행 과정
+
+1. CloudFormation으로 LoadBalancer, Autoscaling Group, CodeDeploy 등 인프라 구성
+2. 배포하고자 하는 프로젝트 빌드 파일을 S3로 전송
+3. CodeDeploy를 사용하여 빌드된 프로젝트 파일 배포

+# IaC를 이용한 인프라 구성 / 자동 배포 / 배포 로그 수집
+## CloudFormation 인프라 구성 / CodeDeploy 자동 배포 / CloudWatch 로그 수집
+![cloudformaion.png](./img/cloudformation.png)
+## 전제사항
+* Nodejs 프로젝트 존재
+   * 꼭 Nodejs일 필요는 없으나 Java Spring이나 Django로 바뀌게 될 경우 초기 설정이나 쉘 스크립트 수정이 필요
+* CloudFormation을 사용할 수 있는 IAM 계정 존재
+* CodeDeploy, CloudWatch Agent 설치된 AMI
+    * AMI 없이 UserData로 설치 가능
+* 빌드 파일을 실행하기 위한 요소(Node or Java)가 설치된 AMI 존재
+    * AMI 없이 UserData로 설치 가능
+* 프로젝트에 CodeDeploy 스펙을 정의한 appspec.yml 파일 존재
+
+## 자동 배포 진행 과정
+
+1. CloudFormation으로 LoadBalancer, Autoscaling Group, CodeDeploy 등 인프라 구성
+2. 배포하고자 하는 프로젝트 빌드 파일을 S3로 전송
+3. CodeDeploy를 사용하여 빌드된 프로젝트 파일 배포
+
+# CloudFormation 인프라 구성
+
+## json 또는 yaml 형식으로 인프라 정의
+* ### Parameters
+      * Parameters의 경우 프로젝트마다 다른 설정값이 필요하거나 입력이 필요한 변수에 대한 정의
+      * 예를 들면 subnetId, keyName, autoscaingMaxSize/Minsize 같은 경우에는 사용자마다 다른 ID나 설정값이 필요
+      * 각각 자신의 설정에 맞게 변경
+```yaml

+    MaxLength: 15
+    MinLength: 2
+    Type: String
+```
+* ### Resource
+    * Resouces에서는 인프라에 대한 세부사항 모두 정의 
+      * VPC부터 시작해서 모든 인프라 세부 요소에 대해서 정의를 할 수 있고 기존에 있는 리소스를 가져와서 사용할 수도 있다.
+* Role 설정
+   * codedeploy가 loadbalancer와 autoscaling을 이용할 수 있도록 하는 설정
+   * Instance가 cloudwatch와 codedeploy를 이용하고 s3로부터 코드를 가져올 수 있도록 하는 설정
