  4. 4. What is Cloud Computing? “Cloud Computing is a paradigm in which information is permanently stored in servers on the internet and cached temporarily on clients that include desktops, entertainment centers, table computers, notebooks, wall computers, hand-helds, sensors, monitors, etc.” - 2008 IEEE Internet Computing
  5. 5. History Concept has existed since the 60s The term ‘Cloud’ originates from telecommunications world of 1990s John McCarthy – proposed the idea of computation being delivered as a public utility Ramnath K. Chellappa – first academic definition  a computing paradigm where the boundaries of computing will be determined by economic rationale rather than technical limits
  6. 6. History Phases:  Supercomputer  Single machine with many processors plugged into it  Cluster computing  Collection of many smaller machines, each with a few number of processors and independent memory  Grid computing  Expands techniques of clustering but computers that form the grid are pooled from different administrative domains and applied to a common task

  10. 10. Architecture Most of the infrastructure consists of reliable services delivered through data centers that are built on servers with different levels of virtualization technologies Open standards and open software are critical to the growth and survival of Cloud computing.

  14. 14. Architectural Layers & Services Software as a Service Platform as a Service Infrastructure as a Service
  15. 15. Architectural Layers & Services Software as a Service (SaaS)  Term was coined by John Koenig in 2005  Software application delivery model where the vendor develops and operates the software application for use by its customers via the internet
  16. 16. Architectural Layers & Services  Platform as a Service (PaaS)  Provision of an environment that supports the life cycle of web-application development available over the internet  Design  Implementation  Testing  Deployment  Hosting
  17. 17. Architectural Layers & Services Infrastructure as a Service (IaaS)  Delivery of basic storage and computing capabilities as standardized services over the internet.  Provides:  Software  Memory  Data center space  Storage
  18. 18. Out-lines Introduction  What is Cloud Computing  History Architectural Layers & Cloud Services  Software as a Service  Platform as a Service  Infrastructure as a Service Types of Clouds Why migrate to the Cloud? Effectiveness Limitations Issues & Concerns Conclusion
  19. 19. Types of Clouds  Public  External (3rd party provider)  Private  Internal  Hybrid  Both
  20. 20. Role Players Cloud Providers Provide infrastructure to SaaS providers and Cloud users Amazon Salesforce.com SaaS Providers/Cloud Users Companies and web application developers that make use of resources made available to them by Cloud Providers SaaS Users Naïve end-users. Have little or no knowledge about what goes on behind the Clouds.
  21. 21. Outline Introduction What is Cloud Computing History Architectural Layers & Cloud Services Software as a Service Platform as a Service Infrastructure as a Service Types of Clouds Why migrate to the Cloud? Effectiveness Issues & Concerns Conclusion
  22. 22. Why migrate to the Cloud?  Pay-per-use model  Only pay for what you use  Low cost of renting  Amazon Scalable Service (S3) charges $0.12 to $0.15 per gigabyte per month  Reduce runtime and response time  Split operations among multiple computing nodes
  23. 23. Why migrate to the Cloud?  Security  Advanced encryption algorithms  Transparency  Just use the services, cloud maintenance is for the providers to worry about
  24. 24. Effectiveness of Cloud Computing New York Times’ TimesMachine Convert articles from 1851 – 1922 to PDF format Could have taken 7 weeks but with cloud computing technology, project was completed in 24 hours. Animoto Scaled easily from 50 to 3500 servers in just 3 days MapReduce Divide and conquer method is distributed across multiple computers.
  25. 25. Outline Introduction What is Cloud Computing History Architectural Layers & Cloud Services Software as a Service Platform as a Service Infrastructure as a Service Types of Clouds Why migrate to the Cloud? Effectiveness Issues & Concerns Conclusion
  26. 26. Issues & Concerns  Reliability  Will the system be available all the time?  January 2009: 40-minute outage at Salesforce.com  Affected over 900,000 subscribers  Portability  Are services (business applications etc) and data available from anywhere?
  27. 27. Issues & Concerns  Privacy & Security  Who has access to what resources  What happens to your private data if  You fail to pay your bills and your account is terminated?  Government prompts your cloud provider for it?
  28. 28. Conclusion  Cloud computing is here to stay  There still exists the possibility of a single point of failure, but probability of a failure is low because of how well the infrastructure is implemented.  It’s ability to expand and contract on demand makes it very ideal for businesses
