The Construction And Test Of Mobile Corporation's Cloud Computing Platform

Since the concept of Cloud Computing was firstly proposed by an engineer in Google in 2006, the technology of Cloud Computing has been developing rapidly. Although Cloud Computing is not a new technology, it is a new combination of some mature technologies, such as distributed computing, parallel computing, grid computing and virtualization technology. As some IT companies such as Google, Amazon, IBM develop Cloud Computing platforms rapidly, some domestic companies such as china mobile, alibaba, have also joined the ranks of Cloud Computing research and development.Firstly, this paper reviewed the characteristics and composition of the three typical Cloud Computing platforms (Google, Amazon and AZure), and then analyzed their service types, computing services and storage services.Secondly, we discussed the modes, key technologies and architecture level of Cloud Computing. Cloud Computing model includes five key characteristics, three service models and four deployment models, and the key technologies mainly include virtualization technology which can make cloud service providers to save costs and improve cloud security. Cloud Computing architecture can be divided into levels Infrastructure as a service, Platform as a service and software as a service.Later, we made detailed analysis on the Hadoop and Eucalyptus which can be regarded as open source Cloud Computing platform. The analysis objects included the reading and writing process of hadoop, computing model and the architecture of Eucalyptus.In view of that, we designed a Cloud Computing platform, which was composed of service models provided by Hadoop and Eucalyptus. This platform was able to provide infrastructure services and platform services and change the state that existing cloud computing platform can just provide a single service. We also analyzed some key technologies such as virtualization, cloud security, resource scheduling and energy management in this cloud computing platform.Finally, we installed and configured the cloud computing platform components, then ran the test and implemented the cloud computing platform. The test show, this cloud computing platform can provide PaaS and IaaS at the same time, and it meet the user demand of multiple services.
