# Lambda 함수

## 리소스 유형

`AWS.Lambda.Function`

## 리소스 ID 형식

Lambda 함수의 경우 리소스 ID는 ARN입니다.

`arn:aws:lambda:us-west-2:123456789012:function:example-function`

## 배경

AWS Lambda는 서버를 프로비저닝하거나 관리하지 않고도 코드를 실행할 수 있게 해주는 컴퓨팅 서비스입니다.

## 필드

| 필드    | 유형    | 설명                                                            |
| ----- | ----- | ------------------------------------------------------------- |
| `정책`  | `맵`   | 다음 항목을 포함하는 매핑 `정책` (리소스 기반 정책) 및 `RevisionId` (정책의 현재 개정판) 키 |
| `환경`  | `맵`   | 함수의 환경 변수와 오류 상태                                              |
| `런타임` | `문자열` | 예를 들어 함수의 런타임 환경인 `go1.x` 또는 `python3.x`                      |
