Monitored Testing service on Cloud

HistoryIn the past computers were clustered together to form a

single larger computer. In the early 1990s Ian Foster and Carl Kesselman came up

with a new concept of “The Grid”. Taking grid further into the service offering, is “The

Cloud”. This takes the concepts of grid computing and wraps it up in a service offered by data centres.

What is Cloud Computing?A pool of highly scalable, abstracted infrastructure that hosts

your application and is billed by consumption.Cloud computing allows consumers and businesses to use

applications without installation and access their personal files at any computer with internet access.

This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth.

Why?The analogy is , If you need milk , would

you buy a cow ? To reduce cost and maintaining overhead.

Segments of Cloud Computing

Application - It's all On Demand.

Pay as per usage.

Can access software over internet from centralized servers. Platform

The platform segment of cloud computing refers to products that are used to deploy internet. Net Suite, Amazon, Google, and Microsoft have also developed platforms that allow users to access applications from centralized servers.

Infrastructure

Infrastructure is the backbone of the entire concept. Infrastructure vendors environments (such as Google gears) that allow users to build applications.

Amazon Elastic Compute Cloud(EC2)

Virtualized Computing Environment. Server instance managed through a web service API. IP Address and Host Names assigned dynamically. Billed based on usage.

What is Monitored Testing service on cloud?

Today, online tests have become an efficient Examination service.

Online Test Monitoring system apart from conducting tests, also provides live/online justification for provided answers.

Using this service, tuning into provided frequencies, number of tests can be conducted in various colleges at same time.

Professors can know who is participating in the test and how many of them answered to given question, by reporting all these details using graphs.

Professors can suggest the students and give hints.Also the students can compare their results with their

classmates.

DescriptionMonitored testing service on cloud: There are mainly two users, professors and students. The professors session will be scheduled where he will

take the test live from a radio station and monitor the students by checking whether they have answered or not, giving hints and suggestions for questions.

The student’s job is to take the test, check their result and compare their results with their fellow mates.

PurposeThe purpose of the project is to create a Monitored testing

service on cloud. This system will be deployed in cloud like Amazon Web Service which will help in reducing the overhead cost and maintenance.

ScopeThe scope of the project is to create a Monitored testing

service on cloud which has a feature of tuning into community radio station and conducting test and monitor the students by giving suggestions remotely.

Existing SystemToday there are many online examination applications.

Students take multiple choice questions and get the results post comparison from the database. There is no provisions where the professors can actively take part and monitor the students live. The students take the test and view their marks. There is no way to compare his performance with other students.

Proposed SystemIn proposed system we will create monitored testing

service where the professors conduct the test for students live. The audio will appear from the community radio and the questions will be pushed on students systems one by one which can be controlled by the professor himself. He will monitor their performance individually and compare with other students. The comparison is displayed in graphical format. Finally this project will be deployed on cloud.

ModulesModule-1: The first module is designed to provide

authentication to professors and students who wish to get connected. The registration details are stored in the database and whenever the user logs in, the user credentials are retrieved to check whether the user is an authorized user or not. The front end is designed using Flex.

Module2: This module is designed for professors. The professor will login at his scheduled time, conduct the test for the students, give hints and suggestions live from radio, and view their marks and compare the marks with other students.

Module3: This module is for students. After getting registered the students take the test and view their performance in graphical format.

Module4: In this module the admin will deploy the entire application on cloud and monitor it on timely basis.
