Methods, systems, and computer program products are provided for developing application definition packages, and deploying the application definition packages at cloud services to produce real-time data analytics applications. In one implementation, a selection is received of an application definition package that defines a real-time data analytics application. The application definition package indicates an application name and includes at least one payload definition, reference data definition, and query definition. A domain name is provided for the real-time data analytics application, and a cloud service is generated that is associated with the domain name. The application definition package is applied to an application template to generate a finalized real-time data analytics package. The finalized real-time data analytics package is instantiated in the cloud service to create a network-accessible instance of the real-time data analytics application.
