예를 들어 설명해 보자…새로 살 집을 찾는다면…

두 가지 선택 :1. 집을 짓는다2. 집을 빌린다

III - 4

집을 짓는다면커스터마이징이 필요하다

tileflooring

Rooffloor plan

landscaping

windows

lighting

짓고 나서는 , 유지보수도 필요하다

III - 5

빌린다면 , 원하는 조건을 찾아 계약한다

골치 아픈 일들이 , 간편해 진다

나중에 낮은 평수로 바꾸거나 높은 평수로 이사하거나…

III - 6

유지 보수 비용이 필요 없고

월세와 전기세 , 수도세…정원사 , 전기기사 , 하수도 공사에 신경 쓸 필요가 없어진다

III - 7

이와 마찬가지로…

우리 주변에는 이미 많은 Cloud 서비스가 존재하며 리소스를 빌려서 이용하기도 한다 .....

High Reliability 서비스무제한 저장 공간

Connecting, Sharing

Cloud 의 장점들…

III - 12

III - 13

누가 서비스해 줄 수 있을까 ?

아무 데이터나 클라우드에 올려 놓을까 ?: Private Cloud 의 필요성

Public Cloud 를 제공할만한 능력을 갖춘회사는 제한적임

호스팅 업체나 컨설팅 전문가가 제공

사용한만큼 지불연단위 계약

Disaster Recovery

실제적으로 무제한 저장 공간과 계산 능력 제공

관리나 복구 회복 환경을 본인이 구축함

용량을 늘리기 위해서는 개인이 서버를 설치
