System Architecture#

The AMP Digital Platform is designed as a modular, web-based system for collecting, processing, storing, and visualizing minigrid data. It is built on the Prospect Energy Platform and supports both national and regional use.

At the national level, each country platform is used to manage local minigrid data, monitor performance, and support reporting. At the regional level, a central platform brings together selected data from the national platforms to provide a broader view of program performance across countries.

Component

Description

Core (Ruby Platform)

Main application where users interact with the platform. It handles the business logic, web interface, APIs and user management.

Data worker

This service processes incoming data, runs background tasks, and supports data transformation and validation.

PostgreSQL/TimescaleDB

This is the main database used to store structure data, including platform records and time-series data from minigrid operations.

MinIO

This is used for storing files and objects such as uploads, reports, and other large data assets.

Grafana

This provides dashboards and visualizations for monitoring performance indicators and trends.

Nginx

This acts as the reverse proxy and routes to the appropriate services.

Faktory

This manages background jobs such as scheduled data processing and task queues.

Data Flow Architecture#

Data Flow Architecture Diagram

The platform follows a simple flow:

  1. Data is collected from minigrid equipment, external systems, or manual uploads.

  2. The data is sent to the platform through the application or APIs.

  3. Background services process and validate the data

  4. Cleaned and structured data is stored in the database.

  5. Files and large objects are stored in object storage.

  6. Dashboards and reports are generated for users through the application and Grafana.
