Definition of cloud computing

What is CloudComputing?
 Cloud computing is a model for enabling ubiquitous,
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.

EssentialCharacteristicsof Cloud
Computing
On-demand self-service.
Broad network access.
Resource pooling.
Rapid elasticity.
Measured service

On-demandself-service
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 provider.

Broad networkaccess.
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, tablets, laptops, and
workstations).

Resourcepooling.
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,
and network bandwidth.

Rapidelasticity.
Rapid elasticity.
 Capabilities can be elastically provisioned and
released, in some cases automatically, to scale rapidly
outward and inward commensurate with demand.
 To the consumer, the capabilities available for
provisioning often appear to be unlimited and can be
appropriated in any quantity at any time.

Measuredservice.
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.

ServiceModels of CloudComputing:
Software as a Service (SaaS).
Platform as a Service (PaaS).
Infrastructure as a Service (IaaS).

Infrastructureas aService(IaaS).
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, and
deployed applications; and possibly limited control of select
networking components (e.g., host firewalls).

Platformas aService(PaaS)
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,
libraries, services, 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 configuration settings for the
application-hosting environment.

Softwareas aService(SaaS)
Software as a Service (SaaS).
 The capability provided to the consumer is to use the provider’s
applications running on a cloud infrastructure*.
 The applications are accessible from various client devices through
either a thin client interface, such as a web browser
(e.g., web-based email), or a program interface.
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.

Deployment Models of Cloud
Computing
Private cloud.
Public cloud.
Community cloud.
Hybrid cloud.

Privatecloud.
Private cloud.
 The cloud infrastructure is provisioned for exclusive
use by a single organization comprising multiple
consumers (e.g., business units). It may be owned,
managed, and operated by the organization, a third
party, or some combination of them, and it may exist on
or off premises.

Publiccloud.
Public cloud.
 The cloud infrastructure is provisioned for open use by the
general public. It may be owned, managed, and operated by
a business, academic, or government organization, or some
combination of them. It exists on the premises of the cloud
provider.

Communitycloud.
Community cloud.
 The cloud infrastructure is provisioned for exclusive use
by a specific community of consumers from organizations
that have shared concerns
 (e.g., mission, security requirements, policy, and
compliance considerations).
 It may be owned, managed, and operated by one or more
of the organizations in the community, a third party, or
some combination of them, and it may exist on or off
premises.

Hybridcloud.
Hybrid cloud.
• The cloud infrastructure is a composition of two or more
distinct cloud infrastructures (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).

CONCLUSION
Cloud computing is recently new technological
development that has the potential to have a great
impact on the world.
 It has many benefits that it provides to it users
and businesses.
A cloud is a type of parallel and distributed
system consisting of a collection of
interconnected and virtualized computers
 That are dynamically provisioned and presented
as one or more unified computing resources
