  2. 2. DEFINITON <br />Cloud Computing<br /><ul><li>Internet and central remote : servers to maintain data and applications.
  3. 3. Applications without installation and access their personal files at any computer with internet access.
  4. 4. Centralizing storage
  5. 5. Memory, Processing, Bandwidth. </li></li></ul><li>CLOUD COMPUTING<br />Infrastructure-as-a-Service (IaaS)<br />Platform-as-a-Service (PaaS)<br />Software-as-a-Service (SaaS)<br />
  6. 6. Infrastructure-as-a-Service(IaaS)<br /><ul><li> Amazon Web Services  virtual server instances</li></ul> unique IP addresses <br /> blocks of storage on demand. <br /><ul><li> Application program interface (API) </li></ul>start, stop, access and <br /> configure their virtual servers and storage. <br /><ul><li> Fuel and water consumed
  7. 7. Utility computing. </li></li></ul><li>Platform-as-a-Service (PaaS)<br /><ul><li> Hosted on the provider's </li></ul> infrastructure. <br /><ul><li> Developers create applications
  8. 8. eg: Force.com, GoogleApps
  9. 9. Not allow software created by </li></ul> customers been move<br />
  10. 10. Software-as-a-Service (SaaS)<br /><ul><li>Interacts with the user through a front-end portal.
  11. 11. Broad market.
  12. 12. From Web-based email
  13. 13. Hosts both the application and the data
  14. 14. free use the service from anywhere.</li></li></ul><li>CLOUD COMPUTING SERVICE PROVIDER<br />Amazon<br />Salesforce<br />Google <br />Microsoft<br />
  15. 15. Example:<br />
  16. 16. Deployment Models<br />
  17. 17. Types of Cloud Computing<br />HYBRID CLOUD<br /><ul><li>Multiple internal and / external providers.

  19. 19. Multiple cloud services users may ease the transition to public cloud services while avoiding issues such as PCI compliance.</li></ul>Private Cloud<br />Public Cloud<br />
  20. 20. Private Cloud<br /><ul><li> also known as internal cloud
  21. 21. Neologism
  22. 22. hosted services to a limited number of people behind a firewall.
  23. 23. wants more control over their data</li></li></ul><li>Public Cloud<br /><ul><li> also known as external cloud.

  25. 25. Self-service basis</li></li></ul><li>SECURITY<br /><ul><li> Strong incentive to maintain trust.
  26. 26. The Cloud Security Alliance </li></ul> non-profit organization formed to promote <br /> the use of best practices for providing <br /> security assurance within Cloud <br /> Computing<br />
  27. 27. Sustainability and Sitting<br /><ul><li> Assumed as green computing.
  28. 28. Siting servers affects the environmental</li></ul> effects of cloud computing.<br /><ul><li> Climate favors cooling, lots of renewable</li></ul> electricity is available, <br /> thus environmental effects will be more<br /> moderate.<br /><ul><li> Countries with favorable conditions, </li></ul>eg; Finland,Sweden and Switzerland<br />
