1. AWS SAM(Serverless Application Model)

AWS Serverless Application Model (AWS SAM)는 코드형 인프라(IaC)를 사용하여 서버리스 애플리케이션을 구축하기 위한 오픈 소스 프레임워크입니다.

테라폼(Terraform), CDK(Cloud Development Kit)과 같은 코드형 인프라 프레임워크다. AWS SAM을 사용하면 YAML이나 JSON 형식으로 선언된 리소스들을 AWS 클라우드포메이션(CloudFormation) 리소스를 통해 AWS 클라우드 배포할 수 있다. 템플릿 형식은 기호에 따라서 선택하면 된다.

SAM을 사용하면 AWS에서 제공하는 람다(lambda), DynamoDB 같은 서버리스(serverless) 리소스들을 연계 및 관리하기 쉽다. 로컬 환경에서도 람다 같은 서버리스 애플리케이션을 실행하고 테스트 할 수 있다.

2. Install AWS SAM CLI

CLI 명령어 도구를 설치해 간단한 AWS SAM 프로젝트를 만들고 로컬 환경과 클라우드 환경에 배포해보자. 우선 CLI 명령어 도구를 설치한다. 홈브루는 공식 저장소(homebrew/core)에서 패키지를 설치한다. AWS에서 제공하는 패키지를 설치하기 위해 홈브루(homebrew) 탭(tap)을 등록한다.

aws/tap 탭을 등록한다.

AWS SAM CLI 도구를 설치한다.

$ brew install aws-sam-cli

3. Create AWS SAM project

이번엔 AWS SAM 프로젝트를 만든다. sam init 명령어를 통해 프로젝트를 초기화한다. 간단한 예제이므로 AWS에서 제공하는 템플릿을 활용한다.

AWS Quick Start Templates을 선택한다.
Hello World Example with Powertools for AWS Lambda 선택한다.
python3.13 런타임 선택한다.
기타 설정은 기본 값 사용한다.
프로젝트 이름은 action-in-blog으로 지정한다.

$ sam init

파이썬 코드는 AWS SAM 배포와 관련해서 크게 중요하지 않다. AWS 배포를 위해 살펴볼 파일들은 다음 두 가지다.

samconfig.toml
- sam deploy --guided 등을 실행할 때 사용자가 입력한 값을 자동 저장하는 설정 파일이다. 이후 sam deploy만으로도 동일 설정을 반복 실행할 수 있도록 한다.
template.yaml
- AWS 리소스(Lambda, API Gateway, DynamoDB 등)를 정의하는 인프라 코드다. AWS 클라우드포메이션을 기반으로 작성되며, SAM이 이 템플릿을 해석해 인프라를 생성한다.

리소스를 정의하는 template.yaml 템플릿 코드를 보면 다음과 같은 섹션들로 나뉜 구조를 갖는다.

Transform
- SAM 템플릿임을 CloudFormation에 알리는 선언이다. 이 줄이 있어야 CloudFormation이 SAM 템플릿 문법을 해석할 수 있다.
Globals
- SAM 템플릿에서 반복되는 설정을 공통(global)으로 지정할 수 있다.
- AWS::Serverless::Function, AWS::Serverless::Api, AWS::Serverless::SimpleTable 리소스들에 대한 공통 속성을 지정할 수 있다.
Description
- 템플릿 또는 스택에 대한 간단한 설명이다.
Parameters
- 템플릿에 전달할 외부 입력 값을 정의한다. 재사용 가능한 템플릿을 만들거나, 배포 시 값을 동적으로 변경하고자 할 때 사용한다.
Mappings
- 키-값 쌍을 미리 정의해 두고 조건적으로 값을 참조할 수 있게 한다. 예를 들어 리전에 따라 다른 AMI ID를 사용할 수 있도록 맵 객체를 정의한다.
Conditions
- 리소스 생성 여부를 조건으로 제어할 수 있게 한다. 보통 Parameters와 함께 사용한다.
Resources
- 실제 AWS 리소스(Lambda, API Gateway, S3 등)를 정의하는 섹션이다.
Outputs
- 스택 생성 후 외부로 출력하고 싶은 값을 정의한다. 예를 들어 Lambda 함수 ARN, API Gateway URL 등이 있다.

이제 AWS에서 제공하는 템플릿 코드를 살펴보자. 위 템플릿 구조를 대입해보면 AWS 람다를 하나 배포한다는 것을 유추할 수 있다. 배포가 완료되면 API Gateway 주소와 AWS 람다 ARN(Amazon Resource Name)을 출력한다.

4. Build AWS SAM project

sam build 명령어로 빌드를 수행한다. 빌드 결과는 프로젝트 .aws-sam 경로에 생성된다.

$ sam build

4. Run AWS SAM project in local environment

AWS SAM CLI를 사용하면 서버리스 애플리케이션을 로컬에서 테스트할 수 있다. 몇 가지 명령어가 있지만, 이번 포스트에선 로컬에서 HTTP 서버를 사용해서 AWS 람다 함수를 실행하는 sam local start-api 명령어를 사용한다.

sam local start-api 명령어로 람다를 실행한다.
8080 포트 번호로 변경한다.

$ sam local start-api -p 8080

No current session found, using default AWS::AccountId
Initializing the lambda functions containers.

You can now browse to the above endpoints to invoke your functions. You do not need to restart/reload SAM CLI while working
on your functions, changes will be reflected instantly/automatically. If you used sam build before running local commands,
you will need to re-run sam build for the changes to be picked up. You only need to restart SAM CLI if you update your AWS

cURL 명령어로 로컬 환경에 배포된 엔드포인트를 호출하면 AWS 람다 함수가 실행된다.

$ curl http://127.0.0.1:8080/hello

{"message":"hello world"}%

5. Deploy AWS SAM project

이번엔 AWS SAM 프로젝트를 클라우드 환경에 배포한다. AWS 클라우드에 배포하기 위한 키, 시크릿, 토큰 정보를 터미널 세션에 준비한다.

export AWS_ACCESS_KEY_ID="YOUR_AWS_ACCESS_KEY_ID"
export AWS_SECRET_ACCESS_KEY="YOUR_AWS_SECRET_ACCESS_KEY"
export AWS_SESSION_TOKEN="YOUR_AWS_SESSION_TOKEN"

sam build --guided 명령어로 빌드 결과를 클라우드에 배포한다.

$ sam deploy --guided

배포 결과를 보면 API 게이트웨이 경로와 AWS 람다 ARN 값을 확인할 수 있다. API 게이트웨이 경로로 호출하면 로컬 환경에서 테스트한 것과 동일한 응답을 받는다.

변경 사항이 있다면 재빌드 후 배포한다. 이후 배포에는 --guided 옵션 없이 명령어를 수행한다. 최초 명령어를 수행할 때 지정한 값들은 samconfig.toml 파일에 저장되어 재사용된다.

배포 시 아래처럼 어떤 부분들이 변경되는지 확인 후 배포할 수 있다. 아래 예시는 /hello 경로를 /hello-world 경로로 변경하는 작업이었다.

AWS::ApiGateway::Deployment 리소스는 기존 리소스가 삭제되고 신규 리소스가 생성된다.
이 외 AWS::Lambda::Function, AWS::Lambda::Permission, AWS::ApiGateway::Stage 리소스 등은 변경이 일어난다.
