    • Evolution of Computing
      Evolution of cloud computing
    • 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.
    • Cloud Computing
      “PAY AS YOU GO”
    • 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
    • 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

    • Virtualization
      Abstract computing platform
      Hypervisor
      intercepts and emulates instructions from VMs, and allows multiple OS to run on a host computer

    • 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.
    • Cloud Vendors
    • Are you in Cloud?
      Google Docs: Online word processing,
      spreadsheet, presentations and collaboration software.
      Picasa: photo sharing site
      YouTube: Online storage of videos.
      Webex: Online meetings.
      Gmail: Online email account
      Gliffy: Online diagram drawing.
      Yahoo! Calendar: An online calendar.
      Linkedln: Social networking for business.

      And many more…..
    • Requires constant
      Not secure
      internet
      connection
      Data can be
      lost
      Disadvantages
      Limited
      Features
      Data
      Lock in
      Speed
    • Future Work
      With Saas, Iaas, Paas the model “Everything as a service” is on the verge of development.
    • 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
    • Distributed Hybrid Cloud Architecture
    • 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.
    • 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
    • Hmm… Cloud
      computing
      seems less cloudy now
