A method and device for providing real-time data service are disclosed. The method includes creating a message engine for receiving real-time data generated by a real-time data source, creating a data processing engine for acquiring the real-time data in the message engine and processing the real-time data to obtain target data, creating a storage engine for storing the target data and providing the target data according to requirement of a real-time data service, and containerizing the message engine, the data processing engine and the storage engine, and constructing a real-time data processing architecture with a containerized message engine, a containerized data processing engine and a containerized storage engine to provide the real-time data service. Embodiments of this disclosure can realize an overall architecture of real-time data reception, real-time data processing, real-time data storage, and real-time data service.
