  • Read replica
    • async로 데이터가 master가 싱크되는 read replica를 만들 수 있음
    • db 종류에 따라 몇개까지 read replica를 만들 수 있는지 결정됨
      • maria db, postgre : ~ 5
      • aurora : ~ 15
    • 읽기 로드를 offload하면서 성능 up
    • 장애가 발생해도 for high durability, read replica를 master로 승격시켜서 빠르게 복구 가능
    • 그때그때 throuhput에 따라 수평적인 확장 가능 (select문)

    • e. rdbms 사용자 정의: 직접 디비를 ec2에 install해야 효율적
