위 글과 연결되는 글임.

NAT Gateway 뿐만 아니라 

아래의 모든 것들을 신경 써주어야 함

EC2 뿐만 아니라 아래 모든 것을 종료해줬어야 했음

Snapshot, AMI, LB, Elastic IP, ECR Repository, EC2 중지 -> 삭제, Nat Gateway

route53 - alb - eip - ec2 이렇게 흘러들어가는 구조였던 것 같음

아래는 서비스 설명

ECR Repository - 컨테이너 이미지를 S3에 저장하는 것 같음

Elastic IP - 고정 IP를 할당해주는 건데, EC2가 중지되었음에도 EC2에 연결되어 있어서 비용이 청구되는 듯.

LB(로드밸런서) - 부하분산 처리. 리소스가 여유 있는 EC2로 요청을 라우팅

AMI - 템플릿 이미지. 이미지를 사용하면 같은 환경으로 EC2들을 여러 대 쉽게 복제 가능함.

Snapshot - 인스턴스의 특정 시점을 백업한 형태. 파일 형태로 저장되어 있음. Snapshot으로 AMI를 만들어서 EC2 복제 등에 활용할 수 있음.

Nat Gateway - VPC에서 인터넷에 연결되지 않은 Private Subnet이 있을 경우, Private Subnet과 인터넷 혹은 다른 AWS 서비스들과의 통신을 도와줌. Nat Gateway에 Elastic IP 할당되어 있어야 함.

참고로 환불 해달라고 했더니

환불 해준단다.

역시 한국산 떼법은 미국놈들한테도 통하나보다

Hi there, Thank you for reaching out to AWS Billing and Accounts team. As discussed on our chat, the charge was related to EC2 NAT Gateway, Elastic Load Balancers and EC2 Container Registry (ECR) .Please note although your account is under free tier, these services are not covered and or exceeded the free tier limits which caused the charge. For more information on the pricing, please see our pricing pages here: https://aws.amazon.com/vpc/pricing/ https://aws.amazon.com/elasticloadbalancing/pricing/?nc=sn&loc=3 https://aws.amazon.com/ecr/pricing/ That being said, I can confirm the above resources have been successfully deleted and you will not receive any further charges. Regarding the billing adjustment, I will need to monitor the account for 24 hours to make sure there is no charge increase. Once that is confirmed, I will look into the billing for the month of December and January period for you. Thank you for your patience and understanding while I work on this for you.
