Research And Application On Key Techniques Of Cloud Portal

With the development of Cloud Computing, software under Cloud platform has alsoincreased greatly, which includes foundamental services、Cloud-based functions、SaaSsoftware and traditional Web services, etc. How to provide these software and Service tousers in an appropriate form is a problem worth of study.Based on the deep analysis of current Cloud platform, Portal and SaaS servicemechanism, etc, this dissertation puts forward a construction of Cloud Portal whichintegrates various functions under Cloud platform, such as user management、servicemanagement、software management and access control, and focuses on the followingaspects:Firstly, it proposes a basic framework of Cloud Portal and makes it real with thecombination of common Potal theory. This framework is a Portal gathering basis functionsof Cloud Computing platform, software and Web Services. Users can access all servicesthrough Web on Cloud platform with the permission of access authority.Secondly, this paper devises a sort of method on a detailed analysis of Open sourceCloud Computing platform and software interface under it, thus software and interfaceunder Cloud platform can be added to Cloud Potal platform which makes it easier for usersto have unfied management over varied functions of Cloud platform. Experimentalverification of integrated interface and software under Hadoop cloud computingframework in Liferay Portal can be seen in the last part of this paper.Finally, this dissertation borrows implementation mechanism of SaaS platform,analyzis method of current mainstream SaaS platform and service idea of SaaS software,puts forward a method that can deploy SaaS software in cloud Portal, dissectsinter-visualization of traditional Web service under Cloud platform and realization of SaaSservice support, devises the Cloud Portal which can support both SaaS software andtraditional Web service.Cloud Portal framework proposed in this paper is a useful exploration of Cloud Computing, which provides a platform for the final landing of Cloud Computing andCloud Service.
