    • 17. Simple management & quotas
    • 18. Time spent on science rather than engineering
  • A 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.
    • 19. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.
    • 20. It is all about outsourcing your infrastructure and applications to run on a remote resource.
  • Grid to Cloud Evolution
    Cloud Computing
    SaaS Computing
    • Next-Generation Internet computing
    • 21. Next-Generation Data Centers
    • 22. Network-based subscriptions to applications
    • 23. Gained momentum
    in 2001
    Utility Computing
    • Offering computing
    resources as a metered service
    • Introduced in late 1990s
    • 24. Solving large problems
    with Parallel computing
    • Made main stream By
    Global Alliance
  • 25.
  • 26. Hosting vs. Cloud Computing
  • 27.
  • 28. 3 Cloud Service Models
  • 29. SaaS
    Software as a Service
    • SAAS –Software as a service
    ▫The major service given as part of Cloud-Computing services.
    ▫The first service
    ▫Most Known and used
    •The application itself is provided by the service provider.
    •Examples:
    ▫Enterprise: SalesForce.Com, Webex, OfficeLive
    ▫User Mail: Gmail, Hotmail
    ▫User Pics: Flickr, Picasa
  • 30. PaaS
    Platform as a Service
    •PAAS –Platform as a Service
    • This is the application development platform that enables the runtime environment for cloud applications.
    • 31. Provides a high-level integrated environment to design, build, test, deploy and update online custom applications.
    •Examples:
    • Google’s AppEngine
    • 32. Sales force apex
  • IaaS
    Infrastructure as a Service
    • IAAS –Ifrastructure as a Service
    • 33. The delivery of computing on demand as a shared service, avoiding the cost of investing in, operating and maintaining the hardware.
    • 34. Delivery of resources such as servers, storage and network components as a service.
    • 35. Removes the need for investing in and maintaining
    the ever evolving hardware & network components.
    • Examples:
    AmazonEC2, Joyent, GoGridRackspace
  • 36. 3 Cloud Service Models
  • 37. SaaS
    Software as a Service
    Advantages
    • low total cost of ownership (TCO).
    • 38. more scalability in using the software.
    • 39. users don’t have to put any effort into installing and upgrading the applications.
    • 40. it can easily and quickly be accessed from anywhere with a web browser.
    • 41. The network issues such as data redundancy, data backup and recovery are also planned and managed by the vendors.
  • SaaS
    Software as a Service
    Examples
    Commercial Services:
    • Salesforce.com
    • 45. emailcloud
  • PaaS
    Platform as a Service
    Advantages
    • It facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers.
    • 46. Easy and quick development
    • 47. Provider manages upgrades, patches and other routine system maintenance.
    • 48. Pay per use
  • PaaS
    Platform as a Service
    Examples
  • IaaS
    Infrastructure as a Service
    Advantages
    1. allows resource Sharing 2. On Demand basis(dynamic)3. Rapid Deployment 4. Location Independent 5. Pay for Use (Cost is greatly reduced) 6. Scalability 7. Uncomplicated Maintenance
  • 51. IaaS
    Infrastructure as a Service
    Examples
  • 53. 4 Cloud Deployment Models
  • Private cloud Deployment Models
    • Private cloud
    • 57. enterprise owned or leased
  • Communitycloud Deployment Models
    • Community cloud
    • 58. shared infrastructure for specific community
  • Hybrid cloud Deployment Models
    • Hybrid cloud
    • 59. composition of two or more clouds
  • Public cloud Deployment Models
    • Public cloud
    • 60. Sold to the public, mega-scale infrastructure
  • BENEFITS OF CLOUD COMPUTING
    • Reduced CostCloud technology is paid incrementally, saving organizations money.
    • 61. Increased StorageOrganizations can store more data than on private computer systems.
    • 62. Highly Automated No longer do IT personnel need to worry about keeping software up to date.
    • 63. FlexibilityCloud computing offers much more flexibility than past computing methods.
    • 64. More Mobility Employees can access information wherever they are, rather than having to remain at their desks.
    • 65. Allows IT to Shift FocusNo longer having to worry about constant server updates and other computing issues, government organizations will be free to concentrate on innovation.
  • DISADVANTAGES OF CLOUD COMPUTING
  • 66. Security Is the Major Challenge
    • Security:
  • DISADVANTAGES OF CLOUD COMPUTING
    • Special customization not possible.
    technological innovation pace is dictated by CSP.
  • 67. Common Security Requirements
  • 68. Conclusion
  • 69. Why Cloud Computing ?
    • Cloud computing is an efficient way to store and maintain data bases, and is an especially helpful tool for businesses who do a lot of sales.
    • 70. Using a platform on the cloud for your business helps everyone who uses it by streamlining data and procedures into one central location.
    • 71. Cloud computing solutions are often less expensive than their software counterparts, another reason why they are a becoming a popular choice among businesses. Pricing is often offered on a per-user basis, so businesses pay a flat fee based on the number of people who use it.
