ABSTRACT
Cloud computing is an on demand service in which distributed resources,
information, software and other devices are provided according totheclient’s
requirement at specific time [1]. Cloud computing involves deploying groups
of remote servers and software networks that allow centralized data storage
and online access to computer services or resources. In this paper, we explore
the different services in different computingplatforms and applications.Cloud
computing is a service, which offers customers to work over the internet [2].

I. INTRODUCTION
This section gives an introduction to Cloud computing. Cloud computing is a
model for enabling convenient, on-demand network access
configurable computingresources (e.g., networks,servers,storage,applications,
and services) that can be rapidly provisioned and released with minimal
management effort or service provider interaction. Cloud computing is also a
new model of business computing is virtualization [4]. It will be widely used in
the near future. The core concept of cloud computingis reducingthe processing
burden on the users. Eventually users use a wide variety of devices, including
PCs, Laptops, Smart Phones, and PDAs to access different kinds of utility
programs, storage, andapplicationdevelopmentplatforms overtheInternet.All
these services offered by cloud computing providers

control the underlying cloud infrastructure including

the deployed applications and possibly application hosting

constraints as to which applications can be deployed. i.e.

access and use an application or service that is hosted in the
cloud. The applications are acces

This section gives an introduction to Cloud computing. Cloud computing is a

configurable computingresources (e.g., networks,servers,storage,applications,
and services) that can be rapidly provisioned and released with minimal
management effort or service provider interaction. Cloud computing is also a

of select networking components (e.g., host firewalls).
IaaS provides basic storage and computing capabilities as
standardized services over the network. Servers, storage
systems, networking equipment, data centre space etc. are
pooled and made available to handle workloads. The
customer would deploy own software on the infrastructure.

Cloud Deployment Models
Cloud Computing has four types of deployment models
shown in Figure 3. These are public, private,
hybrid.
1. Private Cloud
The cloud infrastructure is available to the public on a
commercial basis by the cloud service provider. A consumer
can develop and deploy a service in the cloud with very little
financial outlay compared to the capital
requirements normally associated with other deployment
options.
2. Private Cloud
The cloud infrastructure is maintained and operated for a
specific organization. It may be managed by theorganization
or a third party and may exist on premise or
3. 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, andcompliance
considerations). It may bemanagedbytheorg
third party and may exit on premise or off premise.
4. 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).

Cloud Computing Characteristics
Cloud computing’s characteristics include on
service, measured service, broad network access, rapid
elasticity, and resource pooling.
1. On-demand self-service
A consumer can unilaterally provision computing
capabilities, such as server time and network storage,
needed automatically [9].
2. Measured service
Public cloud providers like Amazon allow companies to
avoid large upfront infrastructure investment, so the small
companies can afford the workloads as per their
requirement.
3. Broad network access
Capabilities are available over the network that promotes
use by heterogeneous thin or thick client platforms (e.g.,
mobile phones, tablets, laptops, and workstations).
4. Rapid elasticity
Capabilities can beelasticallyprovisionedandreleased,scale
rapidly outward and inward commensurate with demand
dynamically.
5. Resource pooling
The resources like storage, servers, memory, Processing
Unit, Network and virtual machines can be pooled and
utilized by multi-tenant fashion with dynamically
provisioning and de-provisioning
Benefits of Cloud Computing
There are some of the possible benefits for those who offer
cloud computing-based services and applications:
Cost Savings – Companies can reduce their capital
expenditures and use operational expenditures fo
increasing their computing capabilities. This is a lower
barrier to entry and also requires fewer in
resources to provide system support.
Scalability/Flexibility – Companies can start with a small
deployment and grow to a large deployment fairl
and then scale back if necessary. Also, the flexibility of cloud
computing allows companies to use extra resources at peak
times, enabling them to satisfy consumer demands.
Reliability – Services using multiple redundant sites can
support business continuity and disaster recovery.

Maintenance – Cloud service providers do the system
maintenance, and access is through APIs that do not require
application installations onto PCs, thus further reducing
maintenance requirements.
Mobile Accessible – Mobile workers have increased
productivity due to systems accessible in an infrastructure
available from anywhere [7].
CONCLUSION
In this paper, we study that the basic of the Cloud computing
that is widely recognized as the widely growing computing
infrastructure [6]. The application of Cloud computing
architecture allows enterprises to achievemoreefficient use
of their IT hardware and software investments. Cloud
computing offers many benefits by allowing users to use
infrastructure like servers, networks, data storages, and
other without impacting to the owner’s organization. This
paper describes the definition, the various services models,
deployment models, characteristics and benefits of cloud
computing. As efficiency and scalability are among the
primary benefits of cloud computing, then it develops cloud-
based applications that are compatible with multiple
platforms. Along with this we have studied the newest
services offered by cloud computing.
