Architecture

Descriptions

Data Generators
The layer shows some example of current and future generators of information for the digital backbone. These sources are responsible for generating data that will be collected and processed by the system.

Data Adapters
Data adapters monitor the data generators for events. They listen for data changes or updates from the data generators and pass the information to the MQTT Broker.

Publish-Subscribe Broker
The MQTT Broker acts as the central communication hub in the pub-sub model. It receives messages from event listeners and distributes them to the appropriate connectors based on specified subscriptions.

Cloud Storage
The cloud storage layer deliniates different storage solutions where data is stored and their associated connector. Currently, we use Aveva PI for our data historian, ProstgreSQL for our key-value storage, and a partitioned drive for our Binary Large Object (BLOB) storage. This solution allows the data storages to be switched out or new ones to be added. These connectors subscribe to the MQTT Broker to receive data. They facilitate the transfer of data from the broker to the various storage systems (PI, PostgresSQL, File Storage).

Retrieval
This layer provides retrieval services that can access data stored in the cloud storage.
