  2. Introduce to Cloud Computing • Cloud computing, one kind of distributed computing technology . • The term Cloud Computing derives from the common depiction in most technology architecture diagrams

  3. ARCHITECTURE

  4. CLOUD COMPUTING HISTORY • In the past computers were clustered together to form a single larger computer. •  the cluster management software ensured that the “best” CPU at that time was used to run the code.

  5. GRID COMPUTING • Grid computing - expands the techniques of clustering • Had to be jumped with the move from clustering to grid was data residency

  6. The Nuts • Storage management • Security provisioning • Data movement

  7. EMC plans • cloud will monitor data usage, and it automatically shunts data around to load-balance data requests and internet traffic, being self tuning to automatically react to surges in demand

  8. Advantages of Cloud Computing • Cloud computing infrastructures can allow enterprises to achieve more efficient use of their IT hardware and software investments. • Cloud computing can reduce computerized equipment cost. • Cloud computing can let user use system conveniently, user can use it anyplace and anytime by Internet.

  9. Advantages of Cloud Computing • Cloud computing can reduce time and human resources cost. • Cloud computing can apply high-speed operation in bioscience and linear programming. • Location of infrastructure in areas with lower costs of real estate and electricity.

  10. 3 LAYERS OF CLOUD COMPUTING • Application layer • Platform layer • Infrastructure layer

  11. AMAZON ELASTIC COMPUTE CLOUD • A commercial web service which allows customers to rent computers on which to run their own computer applications • Allows scalable deployment of applications • Instance -- a virtual private server use by EC2

  12. Google Technology • GFS (Google File System) 分散式資料系統 • Map Reduce 分散式計算系統 • Big Table 分散式儲存系統

  13. GOOGLE SERVICE – GMAIL • Ample mail storage • Integrated contact list • Mobile access

  14. GOOGLE SERVICE – GOOGLE CALENDAR • Sharing is built-in • Integrated contact list • Mobile access

  15. GOOGLE SERVICE –GOOGLE DOCS • Online document creation • Real-time collaboration • Revision history

  16. cloud computing in the future • Security issue • Programmer maintaining, educate employee
