Presentation Transcript

  1. Cloud Computing and GIS Keith T. Weber, GISP GIS Director, ISU

  2. Goal of this presentation • Describe and demystify “The Cloud” • What is it? • How is it different from web services? • ROI and TCO case studies

  3. What is The Cloud • Once upon a time… • Sam the server man discovered his servers were underutilized • To optimize their utilization rate, he made his servers available to others • This was really nothing new, as ISP’s had been around for decades

  4. But… • Sam’s Servers did more than just host HTML pages, they also: • Provided infrastructure solutions • And hosted services that his customers were not capable of hosting • This commercialization of web service hosting became known as…

  5. Cloud Computing

  6. What goes on behind the cloud?

  7. A Definition • Cloud computing is… • On-demand • Self-service services • Delivered in a metered fashion via a network (i.e., the Internet) • A multi-tenancy model • Within an elastic environment

  8. Terms

  9. Virtualization • Similar to logical hard drives, virtualization converts one server into many virtual servers • Requires: • Physical host server • Host OS + Virtualization software = Hypervisor • Management suite software

  10. Multi-tenancy • Virtualized servers used by many

  11. Elasticity • Similar to scalability

  12. Cloud Deployment Models

  13. The Hybrid Model

  14. What services are offered in the Cloud? • If its not just an html hosting service, what services are offered?

  15. aaS • As A Service

  16. Where does GIS fit aaS? • Brainstorm…

  17. How does The Cloud differ from Web Services we already learned about? • Brainstorm

  18. ROI and TCO Scenarios • TCO? • ROI… • Case study #1, a small Idaho county wants to make GIS maps of the county available via the web • Case study #2, large research university wants to make GIS maps available via the web

  19. The Partly Cloudy Approach • Own the base, rent the spike

  20. Considerations • Reasons people are not using the cloud • Security • Service Level Agreement

  21. Questions?
