I. INTRODUCTION
Cloud computing relies on sharing computing resources rather than having local servers or personal
devices to handle applications. The word cloud is used as a metaphor for the internet so the phrase cloud
computing is a type of internet based computing devices such as storage and applications, the goal of cloud
computing is to apply traditional super computing power normally used by military and research facilities to
perform trillions per second in consumer oriented applications such as financial portfolios. To do this cloud
computing uses large networks groups of servers typically running low cost consumer technology with
specialized connections to spread data processing across them.
The stands for connecting the computer systems software needed to make cloud computing work are
not fully defined at present time, many companies to define their cloud environment systems offered by
company like IBM “Blue Cloud”. Cloud computing has started to obtain mass appeal in corporate data centers
as it enables the data center to operate through the process of enabling computing resources to be accessed and
shared as virtual resources in a secure and scalable. The term cloud used to have appears its origins in network
diagrams that represented the internet or various parts of it as schematic clouds, was coined for what happens
when applications and services are moved into the internet cloud. Characteristics of cloud include shared
infrastructure uses a virtualized software model enabling the sharing of physical services storage and
networking capabilities. Dynamic provisioning allows for the provision of services based on current demand
requirements done automatically using software automation and enabling expansion and contraction of service
capability as needed. Network access is the internet from a broad range of devices such as pcs laptops and
mobile devices using standards based on APIs and managed metering uses metering for managing and
optimizing the service and to provide reporting and billing information. Cloud computing is dynamically
scalable because users only have to consume the amount of online computing resources they actually need.
Cloud vendors like Amazon, Google, IBM quite literally sell computer processing power by the every hour.
Cloud computing is task centric because the usage model is based entirely among what users need to achieve
rather than any particular software hardware or network infrastructure.
II. RELATED WORK
The most important benefits of cloud computing are cost and growth self-service access to an available
pool of computing resources users can run in seconds instead of years. Making adjustments to computing
capacity is also fast elastically scalable grid computing. Cloud computing is a pay per use operates at high scale
and automated the efficiency of cloud computing is very compelling as well. The other work reveals that there
are several issues that are holding some organizations back from rushing to the cloud. Some particularly
sensitive applications will remain in while other may take advantage of public clouds other concern is quality of
service since clouds may not be able to fully guarantee service level agreement in terms of performance and
availability. Cloud computing is characterized by real time capabilities such as self-service auto scaling and
charge back but is also based on many established techniques such as grid computing virtualization service

of service and fit. Oracle Cloud computing strategy is to provide the industry most complete integrated set of
products from applications. Oracle provides high performance reliability scalability availability security
portability interoperability characteristics demand before moving important work to public and private cloud.
Organizations are adopting different deployment models for computing on applications at different rates of
speed so oracle supports customers no matter what type of cloud to choose. Oracle provides the most complete
portfolio of software and hardware products to enable organizations to build and deploy manage public and
private PaaS and IaaS. It offers a very broad portfolio of horizontal and industry applications that are deployed
in either a private shared services environment or in a public SaaS model.

HARNESS THE POWER OF DISTRIBUTED PEER REVIEW AND TRANSPARENCY OF
PROCESS
3.1. CloudSim: Cloud computing emerged as the technology for delivering reliable secure sustainable
computational services presents as software infrastructure or platform as service. Moreover these services may
be offered for clients or yet it is possible that both public and private clouds are combined in hybrids clouds. A
suitable alternative of simulation tool is open possibility of evaluating the hypothesis prior to software
development in an environment where one can reproduce tests. In cloud computing access to the infrastructure
incurs payments in real currency simulation based approaches offer significant benefits as it allows cloud
customers to test their services in repeatable and controllable environment free of cost.
3.1.1. Cloud Report: It is a graphical tool that simulates distributed computing environment based on the cloud
computing paradigm uses cloud sim as its simulation engine and provides an easy to use user interface report
generation features and creation of extensions. The application simulates an infrastructure as a service provider
with an arbitrary number of data centers entirely customizable, user can easily set the amount of computational
nodes and their resource configuration includes processing capacity amount of RAM available bandwidth power
consumption. Customer of the LaaS provider are also simulated and entirely customizable can set the number of
virtual machines each customer owns a broker responsible for allocating these virtual machines and resource
consumption algorithms. Each virtual machine has its own configuration that consists of its hypervisor image
size scheduling algorithms for tasks
.
Figure 1 Screen shot shows how to integrate with the data centers
We can compile the cloud report from source or run the jar file. Cloud reports supports the
development of extensions that can be plugged in on execution time using the java reflection API.
3.2. Amazon Elastic Compute: It is a web service that provides resizable compute capacity in the cloud
designed to make web scale computing easier for developers. It allows to obtain configure capacity with
minimal friction and provides with complete control of computing resources. Amazon EC2 reduces the time
required to obtain to boot new server instances to minutes allowing to quickly scaling capacity. Amazon EC2
changes the economics of computing allowing to pay only for capacity that actually use.
Functionality of Amazon presents a true virtual computing environment allowing to use web service
interface to launch instance with a variety of operating systems, loaded with custom application environment

V. COMPARATIVE STUDY
The Main features of EC2 pre-requisits need to be comfortable with command line linux, it does not fit
everyone requirements, it requires people whom require software as a service hosting of servers. Ec2 as
colocation hosting is not the cheapest quite reasonable than existing hosting service provider. It is exceptionally
flexible with its ability to launch instances as required and for use and it has drawbacks risk mentioned further
down, nothing is local so have to only the API and accept the risk of instance, learning threshold is significant to
scare non-geeks. Compare EC2 cloud Sim is to support for modeling and simulation of large scale cloud
computing infrastructure including data centers on single physical computing node and a self-containedplatform
for modeling data centers service brokers scheduling and allocations policies. Unique features of cloud sim are
availability of virtualized engine aids in creation and management of multiple independent virtualized services.
