The choice and construction of cloud and the integration of cloud applications at the business and management levels are two major problems that power generation companies need to solve urgently in the process of informatization construction. This paper introduces the classification of cloud computing and the technical advantages of private cloud

confirming that private cloud is the best

necessary and only choice for power generation companies. By analyzing the key technologies and characteristics of private cloud development

such as virtualization technology

large-scale data storage and management technology

dynamic resource scheduling and management technology

microservices and container technology

a private cloud construction scheme of power generation enterprises based on "Virtualization + Microservice + Docker" mode is proposed. The integrated platform developed based on private cloud integrates various production and management information systems in the life cycle of power generation enterprises

and realizes the connection of cloud applications at the business and management levels. The platform also meets the application requirements of application layer

management layer and decision-making layer

and supports the expansion of future application functions and accumulates technical experience for future enterprise level private cloud applications.
