“CLOUD”: NETWORK BASED COMPUTING IS NOT
NEW; OPPORTUNITIES & RISKS NOT UNIQUE
Important to View Cloud as Part of a Continuum, as Cloud grows due
to more pervasive broadband, processing power and storage

What is Cloud Computing?: the Definition
Cloud computing is a model for enabling convenient, on-demand
network access to a shared pool of configurable computing
resources (e.g., networks, servers, storage, applications, and
services) that can be rapidly provisioned and released with
minimal management effort or service provider interaction.
On-demand self-service: A consumer can unilaterally provision computing
capabilities, such as server time and network storage, as needed automatically without
requiring human interaction with each service’s provider.
Broad network access: Capabilities are available over the network and accessed
through standard mechanisms that promote use by heterogeneous thin or thick client
platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: The provider’s computing resources are pooled to serve multiple
consumers using a multi-tenant model, with different physical and virtual resources
dynamically assigned and reassigned according to consumer demand. There is a sense of
location independence in that the customer generally has no control or knowledge over
the exact location of the provided resources but may be able to specify location at a
higher level of abstraction (e.g., country, state, or datacenter). Examples of resources
include storage, processing, memory, network bandwidth, and virtual machines.
Rapid elasticity: Capabilities can be rapidly and elastically provisioned, in some cases
automatically, to quickly scale out and rapidly released to quickly scale in. To the
consumer, the capabilities available for provisioning often appear to be unlimited and can
be purchased in any quantity at any time.
Measured Service: Cloud systems automatically control and optimize resource use by
leveraging a metering capability at some level of abstraction appropriate to the type of
service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage
can be monitored, controlled, and reported providing transparency for both the provider
and consumer of the utilized service.

Benefits to Companies and Governments
Cloud Based Services are ideal for those that:
•
Need quick access to scalable computing resources
•
Expect constant changes in resource requirements

Do not require higher level managed services

Are very cost conscious & do not want to use Capital Expense
(CapEx) dollars on complex equipment

Want to transfer burden of reliability and security to network cloud
provider

Want accessibility from anywhere on any device

Good for entrepreneurs with innovative ideas but limited
infrastructure and resources

Good for developing country e-Gov initiatives that need to scale
over time (e-Health; e-Education)

Self Regulatory Initiatives are beginning to develop best practices
Concerns Documented: What Public and
Private Efforts Will Lead the Solutions?
