Method for Calculating Number of Backup Applications in Server Cluster of Regulation Cloud

Regulation cloud platform is clearly proposed in the 13th Five-Year Plan of State Grid Corporation of China’s informatization. In order to meet the growing demand for business and technology development. At present, applications of regulation cloud need to run in server clusters. To ensure the stable operation of the platform, each application needs to be backed up by several other machines. This paper proposes a method which can calculate the number of backup server for an application, make the use of hardware source more rational and the platform more stable.
