The traditional data service system, which is developed in the form of central control and large integrated single architecture, has poor service experience due to its difficulty in adding new functions and long version update cycles. This paper puts forward the construction idea of the meteorological service support system based on the microservice architecture, which subdivides and atomizes the system functions and encapsulates the services. At the same time, according to different service characteristics, different mature technologies are used for different operation segments, and finally, the unit installation is carried out. Thus, under the premise of perfect realization of various design goals, the system further has the characteristics of agile development, continuous function update and release, and hot service update. At the same time, the system performance is greatly improved by using distributed deployment, elastic expansion and other technology applications.
