What is Cloud?

Definition

Cloud is a model for enabling
convenient, on
-
demand network
access to a shared pool of
configurable computing
resources* that can be rapidly
provisioned and released with
minimal management effort or
service provider interaction.

* Configurable computing resources,

such as networks, servers, storage,

and applications.

Essential Characteristics


On
-
demand self service


Ubiquitous network access


Location independent resource
pooling


Rapid elasticity


Measured service

Basic Concepts of Cloud Computing


You receive IT resources or
services over the Internet


Utility based


you pay based on
usage


Resources delivered by the Cloud
can be easily scaled up and down


You don’t care how the
resources/services are physically
implemented within the Cloud


You don’t need to manage the
underlying infrastructure

their own applications

on cloud infrastructure

managed by the service

Provider.

Approaches to Cloud Deployment


Private Cloud
:

Infrastructure is deployed and
operated exclusively for an organization or
enterprise


May be managed by the organization or by an
independent 3rd party


May exist on
-
premise or off
-
premise at a hosting facility



Public Cloud
: Infrastructure made available to
general public or many industry
groups/customers


Owned by the organization promoting & selling cloud
services


Accessed via standard internet network protocols (i.e.
web browser)



Hybrid Cloud
:

Composition of two or more
clouds, private and/or public


Each cloud retains its unique entities


Clouds may be federated or bound together by
technology enabling data and application portability
