Abstract：In the past few years, there has been a rapid growth in cloud computing. Domestic Internet companies generally use cloud computing service to improve the development efficiency and reduce development costs. In the current cloud practice, the cloud computing platform has a large scale of application scenarios, and even has a trend of larger scale. However, large scale cloud service is not suitable for special environments which have limited resources and lack stability. Therefore, we propose a cloud platform with high availability supporting cloud collaboration. It uses incremental mirroring backup mode to solve the transport problem under bad links, uses multiple clouds resource scheduling strategy to integrate resources and puts forward a running mechanism between clouds to solve the disaster recovery problem of cloud platform. Then, a high availability cloud platform, which can also run steadily in a special environment, is finally implemented.
