Implementation of Cloud Computing In Education – A Revolution Suds Mathew Abstract-? Innovation is necessary to ride the inevitable tide of change and one such hot recent area of research in Information Technology (IT) is cloud computing Cloud computing Is a tolerated computing technology offering required software and hardware through Internet. It also provides storage, computational platform end Infrastructure which are demanded by the user according to their requirement.
Due o the growing need of infrastructure educational institutes, organizations have to spend a large amount on their infrastructure to fulfill the needs and demands of the users. Cloud computing is a next generation platform that allows institutions and organizations with a dynamic pools to resource and to reduce cost through Improved utilization. In the present scenario, many education Institutions are facing the problems with the growing need of IT and infrastructure. Cloud computing which Is an emerging technology and which relies on existing technology such as Internet, retaliation, grid computing etc. An be a solution to such problems by providing required infrastructure, software and storage. In this paper a basic research has been carried out to show how cloud computing can be Introduced In the education to Improve teaching, agility and have d cost-effective Infrastructure which can bring d revolution In the field of education. It also tries to bring out Its benefits and limitations. Index Terms-?Information technology, cloud computing, educational institutes, infrastructure, teaching, revolution.

Google have already started providing their faculties for large business group. With the help of cloud computing the platform and application the user uses can be on-campus or off-campus or combination of both depending on the institutions need. Due to the evolution of cloud computing number of services have migrated from the traditional system to the online forum At present, as many universities are trying to update their IT Infrastructure and data, but they are tackling tee challenges which can be solved by cloud computing.
The challenges are; [1] 1) cost: choose the subscription or POGO plan. ) Flexibility cloud computing allows to dynamically scale the Investment in infrastructures as demand fluctuate. 3) Accessibility: making the data and services available publicly without losing the sensitive information II. SERVICES OF CLOUD With an alma to reducing the expenditure to the unlettered for IT Infrastructure and the complexity faced by unlettered and Institutions, the traditional Installed software on the campus computers are now replaced by cloud computing.
Walt ten power AT cloud, today enlarger coeducation can gain gallants flexibility and agility and can migrate the sensitive data into remote and world wide ATA center ‘ the cloud’ itself. To use the cloud services the universities and the institutions has to first define their requirements and has to take a special attention for the privacy and critical issues. There are several cloud services as follows; [2] 1) Infrastructure as a Service (alas): can be used to satisfy the infrastructure needs of the students, faculties or researcher globally or locally with some specific hardware configuration for a specific task. ) Platform as a Service (Pass): certain providers are opening up application platforms to permit customers to build their own application thou the cost and complexity of buying and managing the underlying hardware and software layers. 3) Software as a Service (AAAS): the application service provider is hosting the application which runs and interacts through web browser, hosted desktop or remote client. It eliminates the need to install and run the application on customer own computer and simplifying maintenance and support. ) Computing as a Service (AAAS): providers offer access l. INTRODUCTION The concept of cloud computing dates back to 1960, when John McCarthy opined that “computation may someday be organized as a public utility’. The term ‘cloud computing’ is confusion to many people as the term can be used to mean almost anything. ‘Cloud’ is used as a metaphor for Internet and its main objective is customization and user defined experience. In other words cloud computing provides shared resources, software and information through Internet as a POGO (Pay-as-you-go) basis.
In the recent years, where educational institutes, universities, industries are giving their full contribution in transforming the society and entire world economy. Various researches are carried out to update the present IT infrastructure especially in the area of education. Cloud computing can be a welcomed optioned in the universities and educational institutes for higher studies. It gives a better choice and flexibility to the IT departments by building multipurpose computational infrastructure once and then Manuscript received March 9, 2012; revised May 1 1, 2012.

CLOUD ARCHITECTURE FOR EDUCATION Due to the higher accessibility, availability and efficiency of cloud services many universities, businesses are trying to make use f these services. Today’s cloud computing providers are offering higher education, the opportunity to substitute their data and information in the ‘cloud’ for universities with existing data centers, servers and application replacing these traditional campus machines.
Developing a cloud architecture for education can be distinct according to the purpose and infrastructure of the institution and can be challenging. The universities has to follow all the rules and regulation of the state and country for developing a cloud for education as many countries are very strict in Ross broader transfer of information. Once the university establishes where their data will reside and gives the measure of data security an agreement called SLAP (Service Level Agreement) can be made with the cloud service provider.
The SLAP is a document which can ensure educational cloud users regarding the services provided by the cloud. It tries to identify the users need and simplifies complex issues and creates a relationship between the user and the service provider. It helps to specify the privacy, consistency and integrity. [4] Privacy is one of the important factors which have to be taken care for cloud computing, as the service provider may require some personal information which is related to the data on what the user is trying to store in the cloud.
So the universities should be very careful before disclosing the data and it should not lose the integrity of educational data. There are many solutions that can ensure the security and protection of sensitive data in the cloud. These are; 1) Mask or De-identify of the data 2) Firewalls 3) Encryption and decryption 4) Authorization identity management. Following figure shows the cloud architecture or education; [6] 474 g 2. (D) educational cloud architecture Fig. 2. A) and (b) shows the private and educational cloud architecture for education. Institutes can develop their own cloud called as ‘private cloud’ by making use of their existing resources or multiple universities can come together and can develop a hybrid cloud called as ‘educational cloud’, in which they can share all the resources from the various universities. Private cloud makes use of the local network whereas the educational cloud makes use of public network to access the services provided by he cloud.
