Application Research Of Cloud Computing

Cloud computing is considered as important as the next generation Internet. It has caused universal attention by domestic and foreign operators. On the one hand, it can optimize IT resources, reduce the operating costs of enterprise.On the other hand, it is a key point to develop IT business. By constructing business platforms based on cloud computing, the operation cost and the cost to provide new services can be reduced. The accumulation of telecom operators in the data center, network, users and channel, make its with a unique advantage in constructing the low cost, infinite expansion of the computing and storage ability.Carry out the IT services based on cloud computing is new opportunities for telecom operators.At present, cloud computing is a rising industry, industrial chain still immature, nor form unified technical standard, the operating system and business model is still in exploration stage, operating mode could not reach the standardization of telecom operator commercial product requirements. Under this background, this topic focus on studing the key technologies of cloud computing which can be applicated in telecom operator. Combined with cloud computing experiment project implementation,verified the feasibility of relevant technical solutions in some scenes. Establishes foundation for future large-scale commercial application of cloud computing.Firstly, the key technologies of cloud computing were studied in this paper, cloud computing services can be divided into infrastructure as a service (IaaS), Platform as a Service (PaaS), software as a service (SaaS) 3 kinds, key technologies including virtualization,distributed processing,online software and operation management technology. Then this paper introduces the cloud computing test project of China telecom, including Project background, targets and contents, IaaS technical architecture design for business platform and IDC. Through the comparison and studing of cloud computing to mainstream manufacturers product technical solutions, puts forward on the selection of key technology. Based on the engineering design, the results of the implementation of the IaaS cloud construction,this paper summarized the evaluation index,and analysised the effects on the project implementation.Finally,this paper summarized the research work,proposed further research work and pointed out the development prospects of cloud computing.
