Introducing to Cloud Computing …
DEFINATION::Cloud computing is the use of computing resources
(hardware and software) that are delivered as a service
over a network (typically the Internet). The name comes
from the use of a cloud-shaped symbol as an abstraction
for the complex infrastructure it contains in system
diagrams. Cloud computing entrusts remote services with a
user's data, software and computation.
The origin of the term cloud computing is obscure, but it
appears to derive from the practice of using drawings of
stylized clouds to denote networks in diagrams of
computing and communications systems. The word cloud is
used as a metaphor for the Internet, based on the
standardized use of a cloud-like shape to denote a network
on telephony schematics and later to depict the Internet in
computer network diagrams as an abstraction of the
underlying infrastructure it represents. The cloud symbol
was used to represent the Internet as early as 1994.
CHARACTERISTICS OF CLOUD
• Agility :-improves with users' ability to re-provision
technological infrastructure resources.
• Application programming interface(API)
accessibility to software that enables machines to interact
with cloud software in the same way the user interface
facilitates interaction between humans and computers.
• Virtualization technology allows servers and
storage devices to be shared and utilization be increased.
Applications can be easily migrated from one physical server
• Reliability is improved if multiple redundant sites are
used, which makes well-designed cloud computing suitable for
business continuity and disaster recovery

• Maintenance of cloud computing applications is
easier, because they do not need to be installed on each
user's computer and can be accessed from different

Infrastructure as a service (IaaS)
In this most basic cloud service model, cloud providers offer
computers, as physical or more often as virtual machines, and other
To deploy their applications, cloud users then install operating
system images on the machines as well as their application
software. In this model, it is the cloud user who is responsible for
patching and maintaining the operating systems and application
software. Cloud providers typically bill IaaS services on a utility
computing basis, that is, cost will reflect the amount of resources
allocated and consumed.
Platform as a service (PaaS)
In the PaaS model, cloud providers deliver a computing
platform typically including operating system, programming
language execution environment, database, and web server.
Application developers can develop and run their software
solutions on a cloud platform without the cost and
complexity of buying and managing the underlying
hardware and software layers. With some PaaS offers, the
underlying computer and storage resources scale
automatically to match application demand such that cloud
user does not have to allocate resources manually.
Software as a service (SaaS)
In this model, cloud providers install and operate
application software in the cloud and cloud users access the
software from cloud clients. The cloud users do not manage
the cloud infrastructure and platform on which the
application is running. This eliminates the need to install and
run the application on the cloud user's own computers
simplifying maintenance and support. What makes a cloud
application different from other applications is its elasticity
Users access cloud computing using networked client devices, such as ,
and smart phones.
Some of these devices - cloud clients - rely on cloud computing for all or
a majority of their applications so as to be essentially useless without it.
Examples are thin clients and the browser-based Chrome book.Many cloud
applications do not require specific software on the client and instead use a
web browser to interact with the cloud application. With Ajax and HTML5
these Web user interfaces can achieve a similar or even better look and feel as
native applications. Some cloud applications, however, support specific client
software dedicated to these applications (e.g., virtual desktop clients and
most email clients)
Public cloud applications, storage, and other resources are made available to
the general public by a service provider. These services are free or offered on a
pay-per-use model. Generally, public cloud service providers like Amazon AWS,
Microsoft and Google own and operate the infrastructure and offer access only
via Internet (direct connectivity is not offered).
Community cloud shares infrastructure between several organizations from a
specific community with common concerns (security, compliance, jurisdiction,
etc.), whether managed internally or by a third-party and hosted internally or
externally. The costs are spread over fewer users than a public cloud (but more
than a private cloud), so only some of the cost savings potential of cloud
computing are realized.
By utilizing "hybrid cloud" architecture, companies and individuals are able to
obtain degrees of fault tolerance combined with locally immediate usability
without dependency on internet connectivity. Hybrid cloud architecture
requires both on-premises resources and off-site (remote) server-based cloud
Private cloud is cloud infrastructure operated solely for a single organization,
whether managed internally or by a third-party and hosted internally or
externally. Undertaking a private cloud project requires a significant level and
degree of engagement to virtualized the business environment, and it will
require the organization to reevaluate decisions about existing resources. When
it is done right,
Invention in future….
Hi frnd ,this is the
invention of cloud
computing in future.
After near about 6 to 7
years you will see the key
for cloud on your
laptop ,mobile ,and pc.
