History
John McCarthy (1927~2011)
Time-Sharing Technology
• “The ubiquitous availability of high
 capacity networks, low cost
 computers and storage devices as
 well as the widespread adoption of
 virtualisation, service-oriented
 architecture, autonomic, and utility
 computing have led to a tremendous
 growth in cloud computing.”

  26. 역사?\n
  27. 존 맥카시(1927-2011)\nLISP, ALGOL 언어 개발.\n튜링상 수상\n
  28. 시분할 기술(하나의 장치를 둘 이상의 목적 또는 많은 사용자을 위해 시간대를 나누어서 사용함. 예를 들면 같은 컴퓨터를 몇 개의 다른 프로그램에 대해서 시분할적으로 사용) 제안. \n컴퓨터와 망이 수도와 전기처럼 사용.\n클라우드 컴퓨팅, 그리드 컴퓨팅의 기반.\n
  29. 1960년대 이후로 지지부진하다가(성능의제약, 펜티엄?)\n최근 클라우드의 폭발적인 발전.\n모바일디바이스, 망, 저장매체, 데이터 주고받는일이 늘어나\n\n
  30. 1960년대 이후로 지지부진하다가(성능의제약, 펜티엄?)\n최근 클라우드의 폭발적인 발전.\n모바일디바이스, 망, 저장매체, 데이터 주고받는일이 늘어나\n\n
  31. 1960년대 이후로 지지부진하다가(성능의제약, 펜티엄?)\n최근 클라우드의 폭발적인 발전.\n모바일디바이스, 망, 저장매체, 데이터 주고받는일이 늘어나\n\n
  32. 1960년대 이후로 지지부진하다가(성능의제약, 펜티엄?)\n최근 클라우드의 폭발적인 발전.\n모바일디바이스, 망, 저장매체, 데이터 주고받는일이 늘어나\n\n
  33. 좀 더 자세히\n1.언제든 접근 가능한 고속망(3g, lte, wifi)\n2.컴퓨터와 저장매체의 가격 하락.\n(3.가상화)\n
  34. 저장기능(n드라이브, 유클라우드, 다음클라우드) 파일저장 혹은 동기화, 백업\n작업장(iCloud, google docs, Prezi etc) 여러곳, 기기에서 문서작업\n
  35. 클라우드 서비스 모델의 종류:\nInfrastructure as a Service (IaaS)\n순수 저장, 서버 등등\nPlatform as a Service (PaaS)\n가상호스팅, 런타임, DB....\nSoftware as a Service (SaaS)\n일반적인 서비스(웹, 문서, 게임 등)\n
  36. 장점?\n
  37. 컴퓨터 비의존적 - 어느 컴퓨터에서도 똑같은 작업 가능.\n여러사람이 올렸다 내렸다(구글독스)\n저비용, 친환경\n보안높다\n\n
  38. 단점?\n
  39. 인터넷 기반 - 인터넷 빼면 시체(끊기면 못씀)\n정보유출을 배제 x (회사 먹튀, 다른사람 먹튀)\n저성능 - 망의 한계\n망 독점 - 무제한데이터 통화불가, 디미고 토렌트 (QoS)\n
  40. 인터넷 기반 - 인터넷 빼면 시체(끊기면 못씀)\n정보유출을 배제 x (회사 먹튀, 다른사람 먹튀)\n저성능 - 망의 한계\n망 독점 - 무제한데이터 통화불가, 디미고 토렌트 (QoS)\n
  41. \n
