The CIOs approach

• Top down - SaaS

• Bottom up - IaaS


Definitions of “Cloud Computing”

“a style of computing where scalable and elastic IT-enabled

capabilities are delivered as a service to external/internal

customers using Internet technologies” – adapted from Gartner

“IT resources and services that are abstracted from the

underlying infrastructure and provided “on-demand” and “at

scale” in a multi-tenant environment” – Gartner


Gartner’s Five Attributes

Abstraction On-demand Scalable Multi-tenant Metered by use



Abstraction On-Demand Scalable Multi-Tenant Metered by use

• User concerns are abstracted from the Provider through service interfaces that

are well-defined.

• IT Resources and Services is abstracted from the underlying Infrastructure.

• The interfaces hide the implementation details and enable a completely

automated response by the Provider to the User of the service.




• Source only what you need –scaling up or down




• Services share a pool of resources to build economies of scale. IT resources are

used with maximum efficiency.

• The service can scale capacity up or down as the consumer demands at the

speed of full automation (which may be seconds for some services and hours for

others).

• Elasticity is associated with not only scale but also an economic model that

enables scaling in both directions in an automated fashion. This means that

services scale on-demand to add or remove resources as needed.




• Architecture deployed allows the sharing of infrastructure to deliver Dedicated

Services




• Services are tracked with usage metrics to enable multiple payment models.

The service provider has a usage accounting model for measuring the use of the

services, which could then be used to create different pricing plans and models.

• These may include pay-as-you go plans, subscriptions, fixed plans and even free

plans. The implied payment plans will be based on usage, not on the cost of the

equipment.

• These plans are based on the amount of the service used by the consumers,

which may be in terms of hours, data transfers or other use-based attributes

delivered.

End goal =
