  5. 5. Working definition of Cloud Computing<br />Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. <br />
  6. 6. Cloud Computing<br />“PAY AS YOU GO”<br />
  7. 7.
  8. 8. Cloud Service Models<br />Cloud Software as a Service (SaaS)<br />---Use provider’s applications over a network <br />Cloud Platform as a Service (PaaS)<br />---Deploy customer-created applications to a cloud <br />Cloud Infrastructure as a Service (IaaS)<br />---Rent processing, storage, network capacity, and other fundamental computing resources<br />
  9. 9. Cloud Deployment Model<br />Private cloud <br />- enterprise owned or leased<br />Community cloud<br />- shared infrastructure for specific community<br />Public cloud<br />-sold to the public, mega-scale infrastructure<br />Hybrid cloud<br />-composition of two or more clouds<br />

  12. 12. Virtualization<br />Abstract computing platform<br />Hypervisor<br />intercepts and emulates instructions from VMs, and allows multiple OS to run on a host computer<br />
  13. 13. Statistical study of Cloud Computing<br />
  14. 14. Advantages of Cloud Computing <br />Document<br />Unlimited<br />Storage<br />capacity <br />Format<br />Compatibility<br />Reduced software <br />Costs<br />Device<br />Independence<br />Cloud Computing<br />Instant software<br />updates<br />24 /7 support<br />Increased data<br />reliability<br />Flexible<br />Pricing<br />
  15. 15. Role of Open Source<br />Open source software plays an important role in cloud computing by allowing it basic software elements — virtual machine images and appliances — to be created from easily accessible components<br />Open source is shaping cloud - by providing the raw material upon which many private and public clouds are built.<br />
  16. 16. Cloud Vendors<br />
  17. 17. Are you in Cloud?<br />Google Docs: Online word processing,<br />spreadsheet, presentations and collaboration software.<br />Picasa: photo sharing site<br />YouTube: Online storage of videos.<br />Webex: Online meetings.<br /> Gmail: Online email account<br />Gliffy: Online diagram drawing.<br />Yahoo! Calendar: An online calendar.<br />Linkedln: Social networking for business.<br />The business answer to MySpace and FaceBook.<br />Picnik: Online photo editing.<br />Blogger: A service for online publishing blogs.<br />Google: search engine<br />Flickr: photo sharing site<br />And many more…..<br />
  18. 18. Requires constant<br />Not secure<br />internet<br />connection<br />Data can be<br />lost<br />Disadvantages<br />Limited<br />Features<br />Data<br />Lock in<br />Speed<br />
  19. 19. Future Work<br />With Saas, Iaas, Paas the model “Everything as a service” is on the verge of development.<br />
  20. 20. At the moment, this is not clear which kind of <br />measures, tools are taken to guarantee the privacy of data<br />There is still hindrance in the path to achieve cloud computing due to non availability of tools<br />There should be scenario for automatic adjustment of bandwidth as traffic increases<br />
  21. 21. Distributed Hybrid Cloud Architecture<br />
  22. 22. Conclusion<br />Benefits of Highly Professional Computing made available to all sizes of Business.<br />No upfront investment – Encourages innovation. <br />Innovators are free to focus on the innovation rather than the logistics of finding and managing resources that enable the innovation.<br />Key Opportunity for application and infrastructure <br />vendors.<br />Environmental Friendly.<br />
  23. 23. Cloud Computing – Tomorrow…<br />All IT companies throwing resources into cloud<br />computing .It will affect all levels of computational<br /> system, from casual user to software developers, <br />IT managers, even hardware manufacturer. <br />It seems like much of world’s digital information will<br />be living in clouds<br />Technology will evolve from services into full<br />fledged operating systems<br />
