cloud usually contains a number of other computing
resources, such as storage area networks, network devices,
firewalls and other security equipment. In describing the
application of cloud computing, it describes a scalable
application through the Internet. Any user can access a cloud
computing application through appropriate equipment and a
standard browser.”
    In cloud computing, the applications needed by users are
not run on users’ personal computers, mobile phones and
other terminal equipment, but on a large-scale cluster of
servers running on the Internet. The user does not deal with
the data stored locally, but stored in the Internet data center
inside. The normal operation of management and
maintenance of these data center is taken charge of
enterprises which provide cloud computing services, and
ensure strong enough computing power and storage space for
the users. At any time and any place, any user can connect to
the Internet terminals. Therefore, whether businesses or
individuals, they can achieve on-demand in the clouds with
the use.                                                                       Figure 1.   System Architecture Model of Cloud Computing Platform

Among them, the key factors of E-Learning are reusing, E-Learning as an important mode of learning today, plays sharing resources and interoperability. an important role in creating a good learning environment of Compared with traditional teaching methods, E-learning personalization and being well adapted to the current is a good carrier of the content. Through a variety of teaching education model no matter when and where can, it also resources effectively organizing, sequencing, processing, it supplies with a convenient communication environment and forms a web-based teaching and better than traditional rich resources for learners. However, the current E-Learning teaching and learning environment, and is able to take full infrastructure is not yet complete[1], does not adequately advantage of a variety of teaching resources. At the same provide for the E-Learning system dynamic allocation of the time, E-learning for teachers and students, between students necessary computing and storage capacity; and the majority and students provides an interactive learning environment of E-Learning system being used was not well interacted, and it can effectively enhance students’ critical thinking and shared data with the others; and as knowledge has not been analytical skills, develop students self-learning ability. From processed by systematic arrangement ,digestion and the perspective of teaching resources, E-Learning is open. absorption, it leads to duplication of teaching resources, E-Learning for learners provides rich learning resources and construction and low utilization, so that the information selects learning materials and learning opportunities. This resources in distance education become isolated island on the feature makes online education has more options than network. In this context, a new type of service computing traditional education [3]. model----cloud computing platform for E-Learning provides the required information technology, so good compatibility III.

In describing the application of cloud computing, it describes a scalable application through the Internet. Any user can access a cloud computing application through appropriate equipment and a standard browser.” In cloud computing, the applications needed by users are not run on users’ personal computers, mobile phones and other terminal equipment, but on a large-scale cluster of servers running on the Internet. The user does not deal with the data stored locally, but stored in the Internet data center inside. The normal operation of management and maintenance of these data center is taken charge of enterprises which provide cloud computing services, and ensure strong enough computing power and storage space for the users. At any time and any place, any user can connect to the Internet terminals. Therefore, whether businesses or individuals, they can achieve on-demand in the clouds with the use. Figure 1.

Under cloud communication technology, information organization computing model, the layer provides management technology and the technology of information management information for upper layer’s resource consolidation. The systems should be made full use of for the building of E- scheduling, combination and utilization of the teaching Learning. A teaching platform can be built by way of open resources are implemented according to the consolidation architecture and modular design in which teaching resources results of the management information. are shared in high degree, communication is extremely The function of the layer of platform integration is to smooth, and cross-platform operations can be executed. a integrate varieties of resources belonged to different collection of a variety of media and new learning features, organizations and different platforms in infrastructure layer. teaching tools. According to the system architecture based on These integrated resources form the basis of teaching cloud computing platform and the feature of E-Learning, the activities. The dispersed, isolated and small-scale teaching application of the architecture on E-Learning is discussed resources are managed in different way using cloud from the perspective of hierarchy architecture. computing model in order to implement the share of teaching The application of the system architecture based on cloud resources. The integration of teaching resources is achieved computing platform on E-Learning is composed of three mainly by data warehouse, data mining and information layers [7] [8]: Infrastructure layer of E-Learning platform, organization technology and combined with scientific Layer of platform integration and Application layer. The management theory. The layer of platform integration also architecture is shown as figure 2. provides the interface of teaching resources managers, users and the Application layer. It is the displaying platform of resource consolidation results. Application layer is the specific applications of integration the teaching resources in the cloud computing model, including interactive courses and sharing the teaching resources. The interactive programs are mainly for the teachers, according to the learners and teaching needs, taken full advantage of the underlying information resources after finishing made, and the course content as well as the progress may at any time adjust according to the feedback, and can be more effectiveness than traditional teaching. Sharing of teaching resources include teaching material resources (such as equipment facilities), teaching information resources (such as digital libraries, information centers), as well as the full sharing of human resources. It can achieve overall scheduling, allocating and utilization of the most teaching resources; improve the teaching efficient use of resources. By then, users only need an Internet web browser or mobile phone and other mobile devices to get the interactive experience, mobility and storage services. In the cloud computing model, E-learning service and data can be shared within the framework to the maximum to avoid the duplication of educational information system’s development. V.
