1. INTRODUCTION
Development of the technology has made several changesin
every field. Cloud computing is such a technology, which
changed the traditional way of learning and accessing the
data in more efficient way. It enables the environment to
consume compute resources as a utility. Mainly there are so
many benefits for both end users and businesses, such as
self-service provisioning which enables end users can turn
up computing resources for almost any type of work load
on-demand. .”Pay-as-use” allowing users to pay only for the
resources and workloads they use. Today many
organizations and businesses are stepping towards this latest
trend of using cloud services. This paper, describes about 1.
Services of E-learning based on cloud computing. 2. Cloud
models used. Cloud computing into an E-learning systems
and its structure to build a sustainable and flourishing E-
learning.
2. SERVICES OF E-LEARNING BASED ON
CLOUD COMPUTING
Cloud computing maintains the storage resources as
services. Services provided by cloud computing can be
classified into three main categories.
a) Software as a Service (SaaS)
b) Platform as a Service(PaaS)
c) Infrastructure as a Service(IaaS)
2.1 Software as a Service (SaaS)
This means Software deployed over the internet. It
facilitates the use of different software applications by the
end user over the internet. This facility has become a
common within every organization among users and buyers
of understanding the technology and what SaaS is and where
to use it .Advantages of using SaaS is Software can be
managed by central location, it delivered in one to many
model, web access to commercial software. Users are not
required to handle upgrading and patching. Simply access
and managed software via a network.
2.2 Platform as a Service (PaaS)
Intermediate layer between SaaS and IaaS. It can be defined
as a computing platform which allows the construction of
web applications quickly and easily and without the
complexity of buying and maintaining the software and
infrastructure underneath it. It is a set of tools and services
designed to make coding and deploying those applications
quick and efficient. Advantages as Multi-level architecture,
where multiple concurrent users utilize the same application.
Services to develop and maintain,test, deploy and host the
application in the same environment.
2.3 Infrastructure as a Service (IaaS)
It’s the common way of delivering the cloud computing
Infrastructure. such as servers, storage, operating systems,
Hardware, Data, Database and network on demand.
Advantages as All the resources are distributed as service,
allow dynamic scaling, include multiple users on a single
piece of hardware.

3. CLOUD MODELS USED
Based on the requirements Cloud computing models are
defined.
3.1 Public Cloud
Service provides on public network engaging with local or
public support. The entire resources and data hub is
transparent to the end user. Public access of shared resources
is provided in the distribution.
3.2 Private Cloud
Service provided in public services is dedicated to only for
particular users to making it private to them. This model
facilitates the organizations being owned by a particular
section with more efficiently to manage their corporate data.
The data is more secured in this type because only a certain
user’s access it and its safe placed under private cloud.
3.3 Common Cloud
Community based model specifically a particular set of
users deployed on a common cloud. Mainly considered as a
public service where it designed mainly for a group of
people who work together.
3.4 Hybrid Cloud
Combination ofdifferent deployment models to make a
dynamic and more efficient way to share the resources.
Mostly it comes under the organizations which outsource the
data.
4. SYSTEM ARCHITECTURE
This section describes the architecture of this system. The
complete system is sub modules into four modules. (A)
Introduction module, (B) Templates module, (C) Question
Answering module and (D) Download module. Each module
is described in detail in the following subsections.
E-learning cloud is the cloud computing technology, where
future learning infrastructure including all hardware and
software computing resources to engage in e-learning.
A. Introduction Module:
This contains a brief introduction of the Instruction Set
Architecture and some detail explanation of the overall flow
of implementation and how to use it. Hence it includes all
kind of architectures and operations.
B. Templates Module:
To expand it and to obtain flexibility, whenever system
overcomes a new question the administrator feels free to add
a particular question and automatically the system generates
the template, as well as answers, and to update the answer
whenever it’s, required but should follow the standard
syntax when developing the templates.
C. Question Answering Module:
Using generic methods answer can be generated. When it
does the statistical techniques it checks with
 Word resemblance
 Distance similarity
 Sentence length similarity
 Word order similarity
This assigns values to reflect the similarity. The sum of
these values is used for comparison. This approach works
rather poorly for short questions and when the query and
FAQ use different wording to carry the same meaning, here
when we use the Template matching approach, the
templates are matched against the question asked by users.
The success of the question answering thus depends a lot on
the quality of these templates.
D. Download Module:
This facilitates users to download the related ISA
Architectures and the other useful documents.
Here in this web based system Cloud E-learning is more
efficient such as planning, implementation, execution and
management.E-leaning will use the cloud computing server,
so that all the resources they need can be adjusted when
necessary.
5. LITERATURE SURVEY
a. In the research of Jain and Chawla they commonly
considered about the advantages of cloud computing
services in E-learning systems, providing architectural
design concept of the system based on Cloud computing
models have been studied, but their performance has
been implemented according to plan the proposed
architecture has been evaluated [1].
b. In Gamundani’s research Cloud based E-learning
system is described and system architecture developed.
This proposed architecture although the elastic
characteristics of the specific features of Cloud
computing architecture will provide all the
characteristic features in high precision[9].
c. Pocatilu, implemented an E-learning system based on
the cloud computing architecture is described and only
the advantages and positive effects of using cloud
computing technology in the field of E-learning is
discussed[10].

6. ADVANTAGES OF CLOUD BASED E-
LEARNING
There are lot of advantages in E-leaning implementation of
cloud computing technology, such as,
1) Least cost
Configuration of each Pc is not needed, all can cloud the
application through PC, mobile phone, tablet PC with a
internet connection. Here they only pay for the storage that
they acquire.
2) Benefit for both students and lecturers
In the sphere of students they can do online exams, courses
and post assignment, projects. Can receive the feedback
from lecturers too. As well as Lecturers can post
assignments, test, take home assignments so in brief both
students and lecturers can have online line contact through
cloud.
3) Updates are always available
In cloud-based applications e-learning parallel run with
automatically updated software. So the learners receive it
always.
4) Security
Information and data are secured here with high precision.
Both the software and the data are stored on remote server
can get crash or vanish without any warning. Cloud
computing provides some major security benefits for
developing E-learning solutions.
5) Higher availability
In any time any environment E-learning is convenient for
students. It considered as learner-centred approach which is
difference among lecturers and they can check there
confidence level of the materials.
7. CONCLUSION
Cloud computing feed positives in various ways with
higher beneficial. Such as maintains storage capacity,
cost effectiveness, software updating and ease of
access and all over complete availability.it can be
developed and integrated with any other utilizable
teaching tools to work more and more for E-learners.
