2Cloud Computing, Hard to Define
3NIST Definition v15
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. This cloud model
promotes availability and is composed of five
essential characteristics, three service models,
and four deployment models.
4Characteristics/Deployment models (NIST)
- On-demand self-service
- Broad network access
- Resource pooling
- Rapid elasticity
- Measured Service
- Private cloud. The cloud infrastructure is
operated solely for an organization. It may be
managed by the organization or a third party and
may exist on premise or off premise. - Community cloud. The cloud infrastructure is
shared by several organizations and supports a
specific community that has shared concerns
(e.g., mission, security requirements, policy,
and compliance considerations). It may be managed
by the organizations or a third party and may
exist on premise or off premise. - Public cloud. The cloud infrastructure is made
available to the general public or a large
industry group and is owned by an organization
selling cloud services. - Hybrid cloud. The cloud infrastructure is a
composition of two or more clouds (private,
community, or public) that remain unique entities
but are bound together by standardized or
proprietary technology that enables data and
application portability (e.g., cloud bursting for
load-balancing between clouds).
5Service Models (NIST)
- Cloud Software as a Service (SaaS). The
capability provided to the consumer is to use the
providers applications running on a cloud
infrastructure. The applications are accessible
from various client devices through a thin client
interface such as a web browser (e.g., web-based
email). The consumer does not manage or control
the underlying cloud infrastructure including
network, servers, operating systems, storage, or
even individual application capabilities, with
the possible exception of limited user-specific
application configuration settings. - Cloud Platform as a Service (PaaS). The
capability provided to the consumer is to deploy
onto the cloud infrastructure consumer-created or
acquired applications created using programming
languages and tools supported by the provider.
The consumer does not manage or control the
underlying cloud infrastructure including
network, servers, operating systems, or storage,
but has control over the deployed applications
and possibly application hosting environment
configurations. - Cloud Infrastructure as a Service (IaaS). The
capability provided to the consumer is to
provision processing, storage, networks, and
other fundamental computing resources where the
consumer is able to deploy and run arbitrary
software, which can include operating systems and
applications. The consumer does not manage or
control the underlying cloud infrastructure but
has control over operating systems, storage,
deployed applications, and possibly limited
control of select networking components (e.g.,
host firewalls).

7Evolution Over The Years
Adoption
Time
8New?
- Cloud computing is an amalgam of mostly existing
technologies and services - Some use models, coupled with scope of
availability and ease of use are part of whats
new - The access and availability of computing, storage
and applications enables individual users to be
content creators, publishers and application
developers. - Further developments and roles are expanding in
new and innovative ways. - Are existing regulatory paradigms relevant or
applicable?
9Virtualization
Virtualization is separating the computing
workload from the hardware. Once computers have
become more or less disembodied, all sorts of
possibilities open up. Virtual machines can be
moved around while running, perhaps to
concentrate them on one server to save energy.
They can have an identical twin which takes over
should the original fail. And they can be sold
prepackaged as virtual applianceseventually to
turn a data centreor even several of theminto a
single pool of computing, storage and networking
resources that can be allocated as needed.

12Cloud Computing Vs. Traditional Hosting Key
Differences
13Familiar Questions
- Cloud?
- Abstraction Layer
- Where is my information?
- Who controls it?
- Who has access?
- How is being used?
- Who is it being shared with?
- Who is looking out for my interests?
14Cloud computing operational concerns the back
end
- Performance/availability/Service Level
- Support
- Interoperability
- Audits/Oversight
- Termination/Lock-in
- Less by design and more by inertia
- Role of open standards
- Portability
15Cloud computing legal concerns
- Privacy
- International data transfers
- Consistent treatment
- Lawful access issues
- Export control
- Data breach notification laws
- Data retention laws
- E-discovery
- Government regulation
- Jurisdiction/Conflict of Laws
16Cloud computing contractual concerns
- All of the operational/legal issues plus -
- Data ownership
- IP
- Limitation of liability issues
- SLAs
- Indemnities
- Subcontracting
- Dispute resolution
- Audits
- Notice/ consent for transfer, where applicable
17Desirable characteristics
