  3. Cloud Computing What is CloudComputing? Cloud Computing offers the ability to access software or information that can be delivered on-demand over the internet ,without the need to store it locality [1,3,4].

  4. Cloud Computing Why Cloud Computing? If you use online photo storage or word processing or online e-mail or an online spreadsheet or online data storage or any other internet-based application, you use “Cloud Computing” [5].

  5. Cloud Computing Cloud’s Services • Software as a Service (SaaS): Any web application is a Cloud application service in the sense that it resides in the Cloud[4,6]. • Google • Amazon • Facebook • Twitter • Flickr

  6. Cloud Computing Cloud’s Services(Cont’d) • Platform as a Service (PaaS): One step up from pure utility computing are Cloud platform services, which hide virtual machine instances behind higher-level APIs[4,6]. • Google Apps • Google AppsEngine • Salesforce’s force.com

  7. Cloud Computing Cloud’s Services(Cont’d) • Infrastructure as a Service (IaaS): Provides raw virtual machine instances, storage, and computation at pay-as-you-go utility pricing, and is currently the leading provider in this category[4,6]. • Amazon Elastic Compute • Cloud(EC2) • Amazon Simple Storage • Service(S3)

  8. Cloud Computing Cloud’s Service Providers

  9. Cloud Computing Types of Clouds • There are three types of clouds[1]: • Private Clouds • Public Clouds • Hybrid Clouds

  10. Cloud Computing Virtualization in Cloud • Virtualization refers primarily to platform virtualization, or the abstraction • of physical IT resources from the users and applications using them[6]. • Virtualization allows servers, storage devices, and other hardware to be • treated as a pool of resources rather than discrete systems[6]. • Virtualization is used to, physical resources into multiple virtual sources • and logic are, as more users can simultaneously use the resources[6].

  11. Cloud Computing Virtualization in Cloud(Cont’d)

  12. Cloud Computing Virtualization Benefits • Higher Utilization Rates: Workloads can be encapsulated and transferred to • idle systems[6]. • Lower Power Usage/Costs: Using virtualization to consolidate makes it • possible to cut total power consumption and save significant costs[6]. • Space Savings: Virtualization can alleviate the strain by consolidating many • virtual systems onto fewer physical systems[6].

  13. Cloud Computing Cloud’s Stack Model

  14. Cloud Computing Compare Clouds & Grids • Architecture: Cloud Grid

  15. Cloud Computing Compare Clouds & Grids(Cont’d)

  16. Cloud Computing Compare Clouds & Grids(Cont’d)

  17. Cloud Computing Cloud’s advantages • Computer costs less • Developed performance • Software costs less • Rapid and permanent improvement • software • More compatible format documents • Unlimited storage capacity

  18. Cloud Computing Cloud’s advantages(Cont’d) • More reliability data • Global access to documents • Having latest version • Group cooperation easier • Independent of hardware

  19. Cloud Computing Cloud’s disadvantages • Need a permanent connection to the Internet • With low speed Internet connection is not • working • Can be slow • Features may be limited • The data stored may not be adequate • security

  20. Cloud Computing Conclusion In summary, we can say that cloud computing model to process the huge volume of information that benefits due to its high computational model as most internet and computer world are discussed.
