ABSTRACT

PC based research facilities are an essential part of the e-learning condition. With the presentation of Cloud

Computing innovations an ever increasing number of labs move into the cloud, known as virtual labs. While

there are numerous advantages for utilizing virtual labs, there is likewise an expansion unpredictability in

regards to the use of them. There are numerous cloud administration frameworks (Cloud MS) which include an

additional layer of multifaceted nature to the e-taking in encounter both from the point of view of the educator

and of the understudy. The reason for the investigation is to recognize approaches to enhance the learning

procedure using distributed computing advances, while lessening the unpredictability related with these

advances the principle center is about the asking for, creation, arrangement, observing and administration of

virtual labs utilizing Cloud Computing. IBM Tivoli Service Automation Manager and VMware Hypervisor are

utilized for building a private cloud. Moodle is utilized as the Course Management System (Course MS). The

proposed Virtual LabCloud System (VLCS) offers one conceivable approach to enhance the learning procedure

by utilizing Cloud Computing to offer Virtual Labs as a Service (VLaaS). The VLCS has the fundamental

objective of offering virtual labs while expanding the cloud assets use. The proposed VLCS makes another

connection between distributed computing and e-learning by giving virtual lab centers as a support of however

many clients as could reasonably be expected while expanding the usage of private cloud assets. This approach

offers the chance to upgrade the e-learning background with better approaches for educating.

Keywords : Cloud Computing, E-Learning, Virtual Labs, Vlab As A Service

I. INTRODUCTION

The adoption of cloud technology within the

instructional environment has the capacity of

offering new opportunities for improvement and

innovation of the gaining knowledge of process. This

paper focuses on deployment, creation , requesting

and virtual lab management using cloud computing.

Currently, maximum of those activities can be

handled by the usage of a few kind of course

management machine (course MS), like IBM Tivoli

carrier Automation supervisor (TSAM) [1], Microsoft

system center 2012 [2],VMware vCloud Suite [3], or

Apache CloudStack [4]. All of those systems where

designed to nice manipulate a Cloud Computing

platform on the infrastructure degree, in different

words for presenting Infrastructure as a service (IaaS)

[5]. IaaS represents the maximum primary cloud-

provider model which generally approach the

supplying of cloud resources as services, for instance,

virtual machines. With using IaaS the extent of

technical information required by means of the end

consumer is the very best whilst comparing with the

opposite fundamental cloud-provider fashions,

Platform as a service(PaaS) [7] and software as a

service (SaaS) [8].

A virtual lab, in this case, is taken into consideration

to be an surroundings composed of precise hardware

and software program configuration which gives

assist for an academic course. usually, a virtual lab

might be represented by a virtual machine (hardware

sources), the operating system (OS) and the required

software and documents (software program sources).

The usage of virtual labs at some universities became

implemented and tested at the IBM CloudBurst [9]

platform which makes use of VMware as a

hypervisor and IBM TSAM as a Cloud MS. Despite

the fact that the simple capability of the virtual labs

is working (introduction of virtual system templates,

deployment of virtual machines based on templates),

there are nevertheless functionalities that are lacking

or tasks that want manual actions so as to be finished.

The following section of the paper addresses the

issues discussed above and the design of VLCS.

II. VIRTUAL LABS CLOUD SYSTEM

The VLCS is a product framework configuration to

fill the necessities of a scholarly domain by making a

connection between a Cloud MS and a Course MS or

E-Learning System, for instance Moodle [10]. VLCS

will speak to another layer for making and

overseeing virtual research facilities. While a Cloud

Management System (either business or open-source)

is compulsory, the presence of a Course Management

System is profoundly prescribed yet a bit much for

the use of the VLCS.

2.1. VLCS goals

The principle goal of the VLCS is to augment the use

of private cloud assets keeping in mind the end goal

to offer access to virtual research centers to however

many clients as could be allowed. This should be

possible by productively checking and booking the

utilization of cloud assets.

The second target is to permit the instructing staff to

center around the advancement of new, imaginative

learning procedures and educational program

without worrying about the many-sided quality

behind the VLCS, specifically the cloud

administration errands.

The third goal of the VLCS is the capacity to

communicate with any (or the same number of)

Cloud MS and Course MS as could be allowed. In the

main phase of advancement, VLCS will offer help for

the accompanying Cloud MS VMware vCenter, IBM

TSAM and Microsoft System Center 2012. With

respect to Course MS or e-Learning System, VLCS

will offer help just for Moodle through a committed

module.

2.2. Virtual Laboratory as a Service

VLCS centers around virtual research centers from

the end-client or instructive point of view.

Consequently VLCS presents the idea of Virtual Labs

as a Service (VLaaS). VLaaS can be seen as another

cloud benefit show which expands the IaaS by

including e-learning usefulness. Utilizing VLaaS,

end-clients still get cloud benefits as virtual machines

and different assets, with the essential contrast that

these administrations are designated to particular

clients or client bunches just with regards to a course

or research center.

2.3. Virtual labs administration

A virtual lab, center substance of the VLCS, is made

out of equipment and programming assets which are

facilitated in a cloud situation, private, open or half

and half. The VLCS has bolster for the accompanying

situations with respect to the administration of

virtual research facilities: predefined virtual lab

utilizing virtual machine formats or custom virtual

lab utilizing on-request virtual machines and extra

programming.

The making of preconfigured virtual machine layouts,

the most tedious movement, requires the setup of the

virtual machine (equipment arrangement),

introducing the OS, the hypervisor apparatuses or

drivers, the antivirus arrangement, including the

required applications and additional records (e.g.

research center manuals, course introduction).

The making of custom virtual machine on-request

implies that a virtual machine is made in view of

1536

client prerequisites without utilizing a preconfigured

format, if assets are accessible and the manager

affirms it (physically or naturally). The end-client

can pick the equipment assets required, similar to the

quantity of CPUs, number of centers per CPU,

memory, storage room, organizing capacities. The

product assets that the end-client could pick are

identified with a rundown of bolstered working

frameworks and any extra programming programs

that ought to be introduce on the virtual machine.

The preconfigured format based arrangement is more

suited for offering virtual labs, since the layouts can

be set up ahead of time, tried and the virtual

machines are made quicker when utilizing formats.

The principle hindrances of this approach are that it

requires watchful arranging, layout creation requires

more opportunity to be made and tried and is less

adaptable to change prerequisites contrasting with

the on-request arrangement.

The custom formation of virtual machines offers

incredible adaptability, yet makes issues for the

utilization arranging of cloud assets. For this

approach the assets made accessible should be

characterized and designed as predefined parts that

can be consolidated on-request by the client. For this

situation, an on-request virtual machine will be

made out of preconfigured parts like equipment

arrangement, bolstered OS and applications.

2.4. Resource scheduling and allocation

VLCS utilizes Role based access control (RBAC)

[11][12] to oversee client access and consents. The

parts characterized in VLCS are autonomous of the

security mechanics accessible in Cloud Management

Systems or Course Management Systems. Right now

VLCS characterizes the accompanying parts, which

can be additionally expanded if necessary: Manager,

Environment Administrator, Content Generator, and

Content Consumer.

The asset designation ask for contains data about the

client who will regulate the virtual machine(s), the

course for which the assets are asked for, the

equipment and programming necessities and time

limits for the accessibility of the cloud assets. The

asset allotment ask for should be affirmed by the

VLCS Environment Administrator before the real

assets are designated. The Environment

Administrator assigns assets just to the course level.

The Content Generator is mindful to additionally

distribute the assets to research centers and Content

Consumers (understudies). For instance, an educator

(Content Generator part) can ask for 30 virtual

machines with a similar equipment design. At that

point, 29 of these VMs will be apportioned to

understudies while one of these VMs can be designed

as a permitting server to be utilized by the other 29

machines. The lifecycle of a virtual lab (figure 1) is

made out of the accompanying components:

Portion of cloud assets to a course. This progression is

typically performed by the VLCS Content Generator

and the demand is endorsed by VLCS Environment

Administrator.

Characterizing the virtual lab inside a course. This

progression is finished by the VLCS Content

Generator. There can be numerous virtual research

facilities for one course, all sharing the cloud assets

assigned at the course level.

Distribution of cloud asset to the virtual research

facility. In this progression the VLCS Content

Generator characterizes which cloud assets

designated for the course will be accessible for the

current virtual research center Allocation of clients

to the virtual lab. Before the VLCS Content

Consumers can utilize the virtual research center the

comparing clients should be added to the ebb and

flow virtual lab. This progression is finished by the

VLCS Content Generator. Client authorizations are

additionally characterized at this progression.

Arranging the virtual lab center. At this progression

the VLCS Content Generator needs to characterize

the VMs arrangement, virtual system design and the

timetable.

Distributing or initiating the virtual research center.

Simply after a virtual lab is distributed the VLCS

begins holding the assets as per the coveted calendar.

This progression is finished by the VLCS Content

Generator.

Covering up or deactivating the virtual research

center. While dealing with the calendar of cloud

assets VLCS does not consider the assets and

timetables of dormant or delayed virtual research

centers. This progression is finished by the VLCS

Content Generator.

Spare the virtual research center setup. This

progression, performed by VLCS Content Generator,

is valuable keeping in mind the end goal to

reproduce or reestablish a virtual lab at a later time.

The spared data about of a virtual lab can incorporate

name, portrayal, assets dispensed, clients distributed,

VMs setup, virtual system arrangement, calendar and

use history.

Expelling the clients from the virtual research facility.

This progression can be performed naturally by

VLCS or physically by VLCS Content Generator

before expelling a virtual lab.

Discharge the cloud assets allotted at first to the

virtual research facility. This progression can be

performed naturally by VLCS or physically by VLCS

Content Generator.

Erase the virtual research facility. This progression is

finished by the VLCS Content Generator.

Discharge cloud assets designated to the course. This

progression can be performed consequently by VLCS

or physically by VLCS Content Generator. The

arrival of assets should be possible incompletely or

absolutely, if all the virtual research centers for that

course are erased.

Keeping in mind the end goal to plan the utilization

of cloud assets the accompanying situations are

secured by the VLCS, in regards to the assignment of

virtual machines: at least one virtual machines for

every client (individual work area) [13] or per

gathering of clients (pooled work area) [14], with

nonstop uptime of the machine or planed (restricted)

uptime of the machine The constrained or planed

uptime of the virtual machine alludes to the

timeframe when the machine ought to be accessible

to utilize. Since this situation can apply to the

scholarly condition, the quantity of clients who can

profit by VLaaS can significantly increment when

contrasting with the constant accessibility of virtual

machines.

III. RELATED WORK

The most related or comparative work to the VLCS

introduced in this paper incorporates Virtual

Computing research center (VCL) [15], Bluesky

cloud structure [16], CloudIA [17], Snow Leopard

Cloud [18], RESERVOIR [19]. These are centered for

the most part around the administration of the cloud

framework, while the VLCS concentrated on

connecting the cloud foundation with the e-learning

condition.

IV. CONCLUSIONS

The proposed VLCS makes another connection

between distributed computing and e-learning by

giving virtual research centers as a support of

however many clients as could be expected under the

circumstances while expanding the use of private

cloud assets. This approach offers the chance to

upgrade the e-learning knowledge with better

approaches for educating.

The VLCS is a software system design to fill the

needs of an academic environment by creating a link

between a Cloud MS and a Course MS or E-Learning

System, for example Moodle [10]. VLCS will

represent a new layer for creating and managing

virtual labs. While a Cloud Management System

(either commercial or open-source) is mandatory, the

existence of a Course Management System is highly

recommended but not necessary for the utilization of

the VLCS.
