    • 1. DISRUPTIVE INNOVATION & ENABLING TECHNOLOGY Cloud Computing Author: Tushprit Singh 0501323108 IT1 (7 th Semester)
    • 2. The “Cloud” = 10X Improvements
      • Ease of Use
      • Scalability
      • Risk
      • Reliability
      • Cost
    • 3. Ease of Use
      • Deploy infrastructure with a mouse or API
        • No cabling, screwdrivers, racking, unboxing, buying
        • Middle of the night
        • Do it yourself remotely from anywhere anytime
    • 4. Scalability
      • See Ease of Use
      • Control your infrastructure with your app
      • Nothing to purchase and take delivery on
      • Instant
    • 5. Risk
      • Nothing to buy
      • Cancel immediately
      • Change instantly, even operating systems
      • Throw it out
      • Rebuild it instantly after testing
    • 6. Reliability
      • Based on enterprise grade hardware
      • Design for failures:
        • Automatically spin up replacements
        • Use multiple clouds
    • 7. Cost
      • “ Turn off the lights” = turn off servers you aren’t using
        • Ex: Turn off development and test environments
      • Pay for only what you use
      • No need to buy in advance
      • Zero Capital Outlay
      • No contracts
    • 8. “ Breaking the Dam(n!)”
      • Colocation – 1 st step to outsourcing
      • Managed Hosting – dedicated servers managed by 3 rd party take some pain away
      • Cloud Hosting – Lower cost, easier, lower risk, more reliable
    • 9. Traditional Hosting Costs Continue to Grow
      • High CapEx
      • Low facility asset utilization (55%)
      • High Depreciation (42-50%)
      • Power/Cooling costs > Server Costs
      • Not “Green”
      • 30% hardware obsolescence

      Multiple Definitions
    • 11. Forrester Research
      • “ A pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end-customer applications and billed by consumption 1 ”
      1- “Is Cloud Computing Ready for The Enterprise?” Forrester Research, Inc.
    • 12. Other Definitions
      • “ Cloud computing is an emerging approach to shared infrastructure in which large pools of systems are linked together to provide IT services.” – IBM press release on “Blue Cloud”
      • “… a hosted infrastructure model that delivers abstracted IT resources over the Internet” – Thomas Weisel Partners LLC from “Into the Clouds: Leveraging Data Centers and the Road to Cloud Computing”
      • “ Cloud computing describes a systems architecture. Period. This particular architecture assumes nothing about the physical location, internal composition or ownership of its component parts.” – James Urquhart blog post
    • 13. Multiple Graphic Descriptions of the “Cloud”
    • 14.
      Redefining the definition
    • 15. Defining the Segments
      • SaaS
        • Software as a Service
        • Storage as a Service
      • PaaS – Platform as a Service
      • IaaS – Infrastructure as a Service
    • 16. Colo vs. Managed vs. Cloud Hosting Colocation Managed Cloud Time Weeks to Months Days to Weeks Minutes Scalability Slowest, Rigid & Costly Slower, somewhat flexible, Costly Instant, Flexible, Pay-per-usage Cost High CapEx Costly, sometimes month/year contracts, no CapEx No contracts, usage based, no upfront costs “ Green” Low Low High - virtualized Pricing model Buy Servers & Colo costs whether used or not Rent Servers & Hosting costs whether used or not Rent based on usage only
    • 17. Hosting Industry Ripe for Change
      • Technology has evolved
      • People demand more control
      • Instant gratification
      • In-house too costly from CapEx and Human Capital
      • Colocation for those who want to be physically there
      • Managed is not dynamic enough
      • Cloud Computing -“Enabling Technology” to move from Traditional Hosting to Cloud Hosting
    • 18. The Cloud’s “Snowball Effect”
      • Maturation of Virtualization Technology
      • Virtualization enables Compute Clouds
      • Compute Clouds create demand for Storage Clouds
      • Storage + Compute Clouds create Cloud Infrastructure
      • Cloud Infrastructure enables Cloud Platforms & Applications
      • Multiple Cloud types lead to Cloud Aggregators
      • Niche requirements enable Cloud Extenders
    • 19. The “Cloud Pyramid”
      • Build upon a foundation
      • Layers equate structure
      • Building blocks: Infrastructure, Platforms, Applications
      • Breadth vs. Niche
    • 20. The “Cloud Pyramid” Inversed
      • 1000’s of Cloud Applications currently
      • Handful of Cloud Platforms
      • Elite group of Cloud Infrastructure providers
      # of Marketplace providers
    • 21. Cloud Computing is…
      • … virtualized compute power and storage delivered via platform-agnostic infrastructures of abstracted hardware and software accessed over the Internet. These shared, on-demand IT resources, are created and disposed of efficiently, are dynamically scalable through a variety of programmatic interfaces and are billed variably based on measurable usage.
    • 22. Cloud “Applications”
      • SaaS resides here
      • Most common Cloud / Many providers of different services
      • Examples : SalesForce, Gmail, Yahoo! Mail, Quicken Online
      • Advantages : Free, Easy, Consumer Adoption
      • Disadvantages : Limited functionality, no control or access to underlying technology
    • 23. Cloud “Platforms”
      • “ Containers”
      • “ Closed” environments
      • Examples : Google App Engine, Heroku, Mosso, Engine Yard, Joyent or (SalesForce Dev Platform)
      • Advantages : Good for developers, more control than “Application” Clouds, tightly configured
      • Disadvantages : Restricted to what is available, other dependencies
    • 24. Cloud “Infrastructure”
      • Provide “Compute” and “Storage” clouds
      • Virtualization layers (hardware/software)
      • Examples : Amazon EC2, GoGrid, Amazon S3, Nirvanix, Linode
      • Advantages : Full control of environments and infrastructure
      • Disadvantages : premium price point, limited competition
    • 25. Cloud “Extenders” (Wild Card)
      • Provides extension to Cloud Infrastructure and Platforms with basic functionality
      • Examples : Amazon SimpleDB, Amazon SQS, Google BigTable
      • Advantages : Extends functionality of Compute & Storage Clouds to integrate with legacy system or other clouds
      • Disadvantages : Sometimes requires use of specific Platforms or Infrastructure
    • 26. Cloud “Aggregators” (Wild Card)
      • Sits on top of various Cloud Infrastructures for management
      • Examples : RightScale, Appistry
      • Advantages : Provides more options for Cloud environments
      • Disadvantages : Dependent on Cloud Providers
    • 27. The NEW “Cloud Pyramid”
