The following are the classes in the data model of the Telemetry Producer subsystem.

Deployment Architecture

This subsystem is deployed using micro-services as shown in the diagram below. The ‘micro’ module is used to implement the micro-services in the system. The subsystem also has an CLI, REST and Web Interface exposed through a nodejs application. The nodejs application will interface with the micro-services and can monitor and drive work-flows through the mesh of micro-services. The deployment of the subsystem is dependent on the environment it is deployed. This subsystem has the following environments:

Physical Architecture

The Telemetry Producer subsystem is physically laid out on a hybrid cloud infrastructure. Each microservice belongs to a secure micro-segmented network. All of the micro-services communicate to each other and the main app through a REST interface. A Command Line Interface (CLI), REST or Web User interface for the app is how other subsystems or actors interact. Requests are forwarded to micro-services through the REST interface of each micro-service. The subsystem has the a unique layout based on the environment the physical space. The following are the environments for this subsystems.

Micro-Services

These are the micro-services for the subsystem. The combination of the micro-services help implement the subsystem’s logic.
