  10. 10. How’d That Cloud Get There?
  11. 11. How’d That Cloud Get There? <ul><li>Computers & networks got faster, cheaper, more accessible & powerful, leading to… </li></ul><ul><li>An explosion in mobile/remote computing and platforms, </li></ul><ul><li>High levels of (desire) collaboration and sharing amongst users, </li></ul><ul><li>Pressure on Data Centres to be always on, always available. </li></ul>Now 60’s-70’s 80’s-90’s 40’s-50’s Future?
  12. 12. How’d That Cloud Get There? <ul><ul><li>Data centres are idle 85% of the time! </li></ul></ul><ul><ul><ul><li>Over-provisioning? </li></ul></ul></ul><ul><ul><ul><li>Redundancy is a must… </li></ul></ul></ul><ul><ul><ul><li>What if that natural disaster never happens? </li></ul></ul></ul><ul><ul><li>This new model offers significant advantages for fast-paced startups, SMBs & enterprises alike. </li></ul></ul><ul><ul><li>Cost effective solutions to key business demands. </li></ul></ul><ul><ul><li>Move workloads to improve efficiency. </li></ul></ul>

  15. 15. There’s Nothing New Under the… Cloud! <ul><ul><li>The “Cloud” is really a metaphor for the Internet . </li></ul></ul><ul><ul><li>Users don’t have or need knowledge, control or ownership of the IT infrastructure. </li></ul></ul><ul><ul><li>Users simply rent or access the infrastructure, “ paying ” only what they use. </li></ul></ul>
  16. 16. There’s Nothing New Under the… Cloud! <ul><li>Cloud computing is using the Internet to : </li></ul><ul><li>… access someone’s software/code/app </li></ul><ul><li>… running on someone else’s hardware </li></ul><ul><li>… in someone else’s data centre </li></ul><ul><li>… while paying for what you use ! </li></ul><ul><li>Client-server? </li></ul><ul><li>New clients, same servers! </li></ul><ul><li>Same distributed computing! </li></ul><ul><li>Same distributed storage! </li></ul><ul><li>How do you pay for Gmail? </li></ul>
  17. 17. What Kind Of Clouds Are Out There?
  18. 18. Definition of Cloud Computing <ul><li>The “cloud model” promotes availability. </li></ul><ul><li>Composed of: </li></ul><ul><li>5 essential characteristics </li></ul><ul><li>4 deployment models </li></ul><ul><li>3 service models </li></ul>Characteristics Deployment Models Service Models
  19. 19. 5 Essential Characteristics <ul><li>On-demand self-service </li></ul><ul><li>Broad network access </li></ul><ul><li>Resource pooling </li></ul><ul><ul><li>Location independence </li></ul></ul><ul><li>Rapid elasticity </li></ul><ul><li>Measured service </li></ul>
  20. 20. 4 Deployment Models <ul><li>Internal (Private) Cloud : The cloud infrastructure is operated within the organization. </li></ul>Main Office + Branches Data Centre
  21. 21. 4 Deployment Models <ul><li>Community Cloud : The cloud is jointly owned by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). </li></ul>Stakeholders Data Centre Internet or Extranet
  22. 22. 4 Deployment Models <ul><li>Public Cloud : The cloud infrastructure is owned by an organization selling cloud services to the general public/companies. </li></ul>Public MegaCorp Data Centre Internet
  23. 23. 4 Deployment Models <ul><li>Hybrid Cloud : Two or more clouds (internal, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability. </li></ul>Main Office + Branches Internal Data Centre Stakeholders MegaCorp Data Centre Internet or Extranet
