Abstract: Cloud computing technology in reducing enterprise information infrastructure investment, improve the information system availability and fault tolerance at the same time, there are difficulties to build the platform,operation and maintenance costs increased, the complexity of computing platform is simplified to build the cloud,based on the cloud computing infrastructure for research, a comprehensive analysis of OpenStack system,combined with the network structure, business integration and server resource planning to explore the feasibility and technical architecture of cloud architecture, and then puts forward the general cloud infrastructure management platform construction method, simplifies the complexity of cloud computing platform, and on the cloud computing platform of automatic fault event trigger and event tracking process, enhance the complexity of the operation and maintenance of the cloud computing platform.

Key words: data center, distributed storage, cloud computing
