Introduction  Faced with the opportunities and challenges of the development of "Internet plus" smart energy, many energy companies are exploring transformation to build a prosperous energy ecosystem. One way is to build an open, shared, agile and flexible energy service platform by using Internet thinking and technologies.

  Method  According to the fast expansion,variability,high reliability requirements of energy service platform, this paper analyzed the incompatibility of traditional monolithic architecture, and proposed the application of microservice architecture for platform construction. Then we introduced the methods and key points of the design and implementation of a micro-service-based "Internet plus" smart energy service platform.

  Result  Based on this method, the author constructed the "Internet plus" smart energy service platform and built multiple energy Internet applications for different users, and implemented the dynamic expansion of business microservice successfully.

  Conclusion  It shows that the "Internet plus" smart energy service platform based on microservice has good scalability, reliability, and deployment flexibility. The platform can support the rapid development of "Internet plus" smart energy business applications.
