  • 4. Evolution of Computing
    Evolution of cloud computing
  • 5. Working definition of Cloud Computing
    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.
  • 6. Cloud Computing
    “PAY AS YOU GO”

  • 8. Cloud Service Models
    Cloud Software as a Service (SaaS)
    ---Use provider’s applications over a network
    Cloud Platform as a Service (PaaS)
    ---Deploy customer-created applications to a cloud
    Cloud Infrastructure as a Service (IaaS)
    ---Rent processing, storage, network capacity, and other fundamental computing resources
  • 9. Cloud Deployment Model
    Private cloud
    - enterprise owned or leased
    Community cloud
    - shared infrastructure for specific community
    Public cloud
    -sold to the public, mega-scale infrastructure
    Hybrid cloud
    -composition of two or more clouds

  • 15. Role of Open Source
    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
    Open source is shaping cloud - by providing the raw material upon which many private and public clouds are built.
  • 16. Cloud Vendors

  • 19. Future Work
    With Saas, Iaas, Paas the model “Everything as a service” is on the verge of development.
  • 20. At the moment, this is not clear which kind of
    measures, tools are taken to guarantee the privacy of data
    There is still hindrance in the path to achieve cloud computing due to non availability of tools
    There should be scenario for automatic adjustment of bandwidth as traffic increases
  • 21. Distributed Hybrid Cloud Architecture
  • 22. Conclusion
    Benefits of Highly Professional Computing made available to all sizes of Business.
    No upfront investment – Encourages innovation.
    Innovators are free to focus on the innovation rather than the logistics of finding and managing resources that enable the innovation.
    Key Opportunity for application and infrastructure
    vendors.
    Environmental Friendly.
  • 23. Cloud Computing – Tomorrow…
    All IT companies throwing resources into cloud
    computing .It will affect all levels of computational
    system, from casual user to software developers,
    IT managers, even hardware manufacturer.
    It seems like much of world’s digital information will
    be living in clouds
    Technology will evolve from services into full
    fledged operating systems
