  9. 9. Gartners  Defini-on  of  Cloud  Compu-ng   The  Cri-cal  A;ributes  of  Cloud  Services  Gartner defines cloud computing as "a style of computing where scalable andelastic IT-related capabilities are provided as a service to external customers using Internet Technologies." Consumer concerns are abstracted from5 Attributes that support outcomes 1 Service Based provider concerns through service interfaces Services scale on-demand to add or remove 2 Scalable & Elastic resources as needed. Services share a pool of resources to build 3 Shared economies of scale. Services are tracked with usage metrics to 4 Metered By Use enable multiple payment models. Services are delivered through use of 5 Internet Technologies Internet Identifiers, Formats, and Protocols.

  12. 12. Public vs. Enterprise Cloud– Is it a Fair Fight?Comparison of very large service with mid-size: (~1000 servers): Large Service [$13/Mb/s/mth]: $0.04/GB Medium [$95/Mb/s/mth]: $0.30/GB (7.1x) Large Service: $4.6/GB/year (2x in 2 Datacenters) Medium: $26.00/GB/year* (5.7x) Large Service: Over 1,000 servers/admin Enterprise: ~140 servers/admin (7.1x)•  Large block h/w purchases significantly more economic –  Large weekly purchases offer significant savings –  H/W Mmanufacturers willing & able to do custom designs at scale•  Automation & custom s/w investments amortize well at scale•  Summary: scale economics strongly in play
