10. Gartner's
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 and
elastic IT-related capabilities are provided 'as a service' to external customers
using Internet Technologies."
Consumer concerns are abstracted from
5 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.

15. 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
