  7. 7. Why cloud? Because cloud enables self-service resource provisioning, it gets your developers productive faster and reduces time-to-market for application development -- and progress. The Cloud Landscape

  11. 11. Public Cloud vs Private Cloud
  12. 12. Public cloud A public cloud is ... A collection of cloud resources accessible in a general pool shared with other customers and maintained by the public cloud provider.
  13. 13. Public Cloud Advantages 1. No initial outlay 2. Instantly available 3. No management concerns 4. Various services (depending on the provider)
  14. 14. Public Cloud Disadvantages 1. No centralized budget control 2. No cost control 3. Data security concerns 4. Data privacy concerns
  15. 15. Private cloud A private cloud is ... A collection of cloud resources accessible in a general pool but kept within a single company, either on premise or serviced by an external company but isolated from other customer workloads.
  16. 16. Private Cloud Advantages 1. Centralized budget control 2. Data control 3. Architecture control 4. Access to legacy systems
  17. 17. Private Cloud Disadvantages 1. Capacity limited by capital outlay 2. Inhouse maintenance requirements 3. Disaster recovery concerns
  18. 18. Hybrid Cloud
  19. 19. Hybrid cloud A hybrid cloud is ... ... a collection of resources that may exist in different cloud structures. Most often, some of these resources are on premises for an organization, and some are not. Workloads can pass between these two (or more) sets of resources.
  20. 20. Hybrid Cloud Use cases 1. Dev/Test in the cloud 2. Alternate location for backup/disaster recovery 3. Load bursting
  21. 21. Hybrid Cloud Horizontal bursting 1. Apps and data begin internally. 2. Systems burst to public clouds when necessary. 3. Loads recede to internal systems when possible.
  22. 22. Hybrid Cloud Vertical bursting 1. Apps are manually placed based on type. 2. Dev/test placed on external cloud until the app is ready to be blessed. 3. Mission/business critical data/apps kept internal.
  23. 23. Hybrid Cloud approaches Datacenter as a Service ● Hosted externally ● Still isolated
  24. 24. Hybrid Cloud approaches Homogenous cloud ● All OpenStack ● All the same APIs How it works at Rackspace
  25. 25. Hybrid Cloud approaches Heterogeneous cloud ● Any type of cloud ● Any other type of cloud >> ?
  26. 26. Summary
  27. 27. ● Cloud consists of several layers ● OpenStack is open source cloud ● Public cloud vs private cloud ● How hybrid cloud is about expanding capacity ● Hybrid cloud can take many forms Summary
