AWS RDS

관리형 PostgreSQL을 운영한다. db.t4g.micro는 $0.016/시간에 스토리지가 추가되며 무료 혜택은 기간 한정이다.

1 무엇을 해주나 — RDS는 PostgreSQL 인스턴스의 설치·운영 작업을 관리형 서비스로 제공한다. 앱은 DB 접속 정보를 사용해 데이터를 읽고 쓴다.

2 무료로 어디까지 — 상시 무료 RDS 인스턴스는 없다. 2025-07-17 이전 계정은 대상 Single-AZ 인스턴스 월 750시간과 gp2 저장 20 GB·백업 20 GB/월을 12개월간 체험할 수 있다. 이후 계정은 신규 고객 크레딧 방식이다.

3 넘으면 얼마 — 2026-10 기준 us-east-1 PostgreSQL db.t4g.micro는 $0.016/시간, 730시간 $11.68에 스토리지 비용이 더해진다. 서울은 $0.025/시간, 730시간 $18.25에 스토리지가 별도다. 데모는 체험·저장·백업·송신을 제외한 인스턴스 시간만 계산한다.

언제 쓰나

PostgreSQL을 쓰면서 DB 서버 운영 부담을 줄일 때 쓴다. 시간 요금만 보지 말고 최소 저장·백업·송신 비용을 합산한다.
