Abstract -Cloud computing is everywhere. If we visitanyIT
companies, it will be sure that they will talk about cloud
computing. But interesting thing is to note that if we asks
about cloud computing to ten different professionals, theywill
give ten different answers, and those are worth.so this cloud
computing is very spread out and wide. Thus cloud computing
can be said as a large warehouse for the data storage. Many
ITs companies has large demand of data storage, which is not
possible on their parts. It would costs huge amount of
economy. Thus it is important to find out an alternate source
for the storage of their data.at the same time, this storage
should be safe, easy to handle and economical. Moreover, it
would provide storage according to the demand and paid
accordingly. Therefore, cloud computing has become a vital
part for all the private sectors as well as governmentsectorsin
order to fulfill their demand.
In this project we are going to deal about all the basis of cloud
computing. What it is? How it works? How it is developed?
How it is deployed and many more. Hence we will clear up all
the misconceptions and make sure we all have a common
understanding of the topic.
Key Words: Cloud Computing; Data Storage; Deployed;
Misconceptions; Developed
1. INTRODUCTION
cloud is an extend of grid computing, distributedcomputing
and parallel computing where everything is serve asservice.
It is a model for enabling convenient, on demand network
accessto a shared pool of configurable computingresources.
Thuscloud computing can be said to provide Internet-based
computing service.
Cloudcomputing builds on already existing computing
technologies, such as, grid computing and virtualisation.
These are the forms of the distributed computing
technologies.
2. BACKGROUND
Cloud computing consists of three models, namely
 SaaS (software –as-a-service)
 PaaS (platform-as-a-service)
 Iaas (Infrastructure-as-a-service)
2.1 SaaS (SOFTWARE –AS-A-SERVICE)
SaaS provides a full-fledged UI for a service or a complete
software application to the user which they can use. Cloud
service providers(CSP) manage the underlyingarchitecture
like operating systems, servers, network and storage along
with application development and maintenance.
The user only uses this software and is completely unaware
of the cloud architecture. User can access such applications
via web browsersfrom desktops, workstations, laptops, etc.
and can also use app on handheld devices if available.
2.2 PaaS (PLATFORM-AS-A-SERVICE)
In PaaS cloud service provides application development
tools, application programming interface, software libraries
and all other services needed for a complete application
development.
Cloud service providersmanagestheunderlyingarchitecture
like operating system, servers, network and storage Users
manage developing, deploying configuring and maintaining
application developed over the cloud.
2.3 IaaS (INFRASTRUCTURE-AS-A-SERVICE)
IaaS provides computing and storage resources to the user
as per requirement. Computing and storage environment is
provided in the virtual manner to the user. This storage
space and computing resources such as RAM, processor
power etc is managed by the user in the virtual space.
The under lying implementation is managed by the cloud
service provider. User can install any OS and applications as
per need on this virtual space provided on the cloud. User

can start, stop, manage and configure this space accordingly
and will be charged as per use.
3 APPLICATIONS
So, now we get to the question-what does cloud computing
actually do? To this, we have applications running on our
laptops, servers and phones. Cloud computing either has
them too or has the potential to bring them to you. Ths cloud
computing brings application a wayof viewing,manipulating
and sharing data.
4 BENEFITS
Cloud computing provides number of offers for the
organization which can be explained below
4.1 SCALABILITY
If a company is anticipating a huge upswing in computing
need, cloud computing can manage. Instead of buying and
configuring new storage, cloud computing provides
additional storage from third party.
4.2 SIMPLICITY
The installation of cloud computing is very simple. It helps
the start ofthe application immediately andit costsafraction
to implement it.
4.3 SECURITY
There are number of security risks when storing any data in
the cloud storage. But reputable companies enforce
themselves to keep their safe and secure.
4.4 STORAGE
Cloud computing provides the user the required storage.
Moreover, cloud computing gives freedom of storing data by
user anytime. Only it needs the internet connections.
5. LIMITATIONS:
Although cloud- storage hasa numerousadvantage/benefits
it provides to the user. But it is restricted by certain
boundaries. Cloud computing is surrounded by a number of
factors which limits its expansion. A user has advantage of
storing its data in the cloud. He/she can store huge bulk of
storage, starting from very basic to very personal. It makes
the cloud computing bound within certainboundaries.There
are always certain possibilities of losing the data stored init.
An ITs companies stores its private, most confidential data
on it, if there get into other hand, it can ruin their company.
Hence the providers always look for the alternate ways of
securing their data. They invest more and more money to
secure their private files by making their security level
upgraded every time. Moreover it has become much easier
for the government to get information from third parties
than from private owned server.
6. DESIGN PRINCIPLES OF CLOUD COMPUTING
Amazon wasthe first company which introducestheconcept
of cloud computing. Amazon used the following concept in
designing the cloud computing.
6.1 DECENTRALISATION: It uses fully decentralized
technique to remove scaling bottlenecks and single point of
failure.
6.2 LOCAL RESPONSIBILITY:Eachindividualcomponent
is responsible for achieving its consistency.
6.3 SYMMETRY: Modes in the system are identical in
terms of functionality, and require no or minimal node-
specific configuration to function.
6.4 AUTONOMY: This system is designed such that
individuals Components can make decision based on the
local information.
6.5 FAILURE TOLERATION: The system consider the
failure of the components to be normal mode of operation
and continues operation with no or minimal interruption.
Other feature includes
 Controlled concurrency
 Controlled parallelism
 Simplicity
7. CONCLUSIONS AND FUTURE SCOPE
In this paper we have discussed about the cloud computing
and its services, quality and advantages. It deals with what
cloud computing is? How it works? How it is developed?
Thus it can be said that cloud computing is beneficial,
convenient and economical for IT industry.

Future scope of cloud computing can be explained as
 Trend of Large Vendors Entering Cloud Computing
Will Accelerate.
 All Major IDEs Will Offer Cloud Deployment
Options,
 Platform-as-a-Service Will Take Its First Steps into
the Mainstream
 A Next-Generation of “Middleware for the Cloud”
will Rise in dominance over Traditional J2EE
Application Servers
 System Administration & Configuration and
Network Management Will Become a Sexy Field
Bursting with Innovation
