+# Lambda VPC 설정과 NAT 없이 구성
+
+- [일반적] VPC가 필요한 서비스들(ex: backend-api)은 외부 필요없도록 구성.
+- [외부용] 외부 연결(https포함) 필요시 VPC없이 돌아가도록
+
+주의! `VPCE` 구성이 필요함.
+
+----------------------
+## 구성 방법
+
+1. Prepare a `Public Subnet` like `public-2a/2c`
+    - 기존 subnet에서 2가지를 고름 (+ 이름 지어주기)
+
+1. Create a `Security Group` like `lemon-services-api`
+    - add in-bound for all traffic from self
+
+1. Create `Endpoints` in VPC for accessing internal AWS
+    - create a security group as `infra-services`.
+        - allow all traffics from `lemon-services-api`
+
+    - add each for `kms`, `sns`, `sqs`, and `execute-api`
+        - security-group: `infra-services`
+        - subnets: `public-2a/2c`
+
+        * kms: `com.amazonaws.ap-northeast-2.kms` w/ `Interface`
+        * sns: `com.amazonaws.ap-northeast-2.sns` w/ `Interface`
+        * sqs: `com.amazonaws.ap-northeast-2.sqs` w/ `Interface`
+        * lambda: `com.amazonaws.ap-northeast-2.lambda` w/ `Interface`
+        * dynamodb: `com.amazonaws.ap-northeast-2.dynamodb` w/ `Gateway`
+
+
+----------------------
+## 배포후 테스트하기
+
+see `lemon-templates-api`, and check `/hello/echo`.
