The Cloud

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."

Internet Technologies Services are delivered through use of Internet Identifiers, Formats, and Protocols. 5

Metered By Use Services are tracked with usage metrics to enable multiple payment models. 4

Shared Services share a pool of resources to build economies of scale. 3

Scalable & Elastic Services scale on-demand to add or remove resources as needed. 2

Service Based Consumer concerns are abstracted from provider concerns through service interfaces 1

Public vs. Enterprise Cloud – Is it a Fair Fight?

•  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

Large Service [$13/Mb/s/mth]: $0.04/GB Medium [$95/Mb/s/mth]: $0.30/GB (7.1x)

Comparison of very large service with mid-size: (~1000 servers):

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)

Summary

Virtual�ization - virtualization, in computing, is the creation of a virtual (rather than actual) version of something, such as a hardware platform, operating system, a storage device or network resources.

The Infrastructure and Operations Scenario — Crucial Trends You Need to Watch

Strategic Planning Assumption: The number of virtualized PCs will grow from less than 5 million in 2007 to 660 million by 2011.

Key Issue: How will virtualization change technology?Key Issue: How will virtualization change technology?

The key technology for defining new rules for device "footprints" is virtualization — a decoupling technology that breaks the close ties between hardware and software. A standard PC installation consists of a stack of multiple layers, the most important being hardware, the OS and applications. Because of the way these layers interact, the configuration of each is tightly coupled with the configuration of the layer below. This is the cause of much of the management complexity of today's PCs, because hardware changes regularly, which has a geometric impact on everything above Virtualization breaks these dependencies so the installation of eachgeometric impact on everything above. Virtualization breaks these dependencies, so the installation of each layer is independent of the configuration of the layer below. On the PC, it occurs at two levels: between hardware and the OS (machine virtualization), and between the OS and applications (application virtualization). On the PC, the impact of virtualization is to decouple the main functional layers. Application virtualization is gaining considerable interest, because key market changes are taking place. This type of virtualization is highly valuable for dealing with current PC management challenges, but it cannot help in the personal versus computing argument. And although more immediately accessible to you, its long-term impact
