Core Components ​

This section provides an overview of the core components and functionalities of AIIDA. The following diagram illustrates the main components and their interaction interfaces:

Core components of AIIDA

AIIDA System ​

The AIIDA system consists of two main parts:

  • the infrastructure hosted by the Eligible Party (EP), and
  • the in-house device installed locally.

AIIDA is not tied to a specific EDDIE instance running at the EP.

Eligible Party Infrastructure ​

The Eligible Party (EP) operates an EDDIE instance with the AIIDA Region Connector enabled.

AIIDA Region Connector ​

The AIIDA Region Connector manages communication between the in-house device and the EP infrastructure. Detailed documentation is available in the EDDIE framework documentation.

EMQX IAM DB ​

The EP infrastructure must include an EMQX IAM database, which handles authentication and authorization for the in-house device and all measuring devices.

EMQX MQTT Broker ​

An EMQX MQTT broker is required to manage MQTT communication between the in-house device and measuring devices. It connects to the EMQX IAM database for authentication and authorization.

The Region Connector handles permission and ACL management for the in-house device but does not process or consume any data published by edge devices.

In-House Device ​

The in-house device can be any system capable of running Docker containers and connecting to the internet. All components are deployed using Docker Compose, as described in the operations guide.

AIIDA Application ​

The AIIDA application is a Spring Boot service that forms the core of the system. It manages:

  • data flow between data sources and the EP infrastructure, and
  • permissions and access control for data sources.

As such, it is the central component of both the system and this documentation.

The AIIDA application exposes a REST and User Interface (UI) for configuration and management.

Keycloak ​

Keycloak provides Identity and Access Management (IAM) for AIIDA. More details are available in the Keycloak documentation in more detail.

TimescaleDB ​

TimescaleDB is the time-series database used by AIIDA to store all in-house device data. Further information can be found in the database documentation.

EMQX MQTT Broker ​

The in-house device also runs an EMQX MQTT broker to handle MQTT communication between local data sources and the AIIDA application. Details are described in the EMQX documentation.

Data Source ​

A data source is a logical representation of any system that provides data to AIIDA - either a physical device (e.g., a smart meter) or a software-based source generating virtual data. More details about data sources can be found in the data source documentation.
