High-level technical architecture

The above diagram contains the main components of our suite. From top to bottom the solution contains the following functionality:

• Frontend services

  • Authentication and Authorization

    • Using OPNsense standards

  • User interfacing

    • Using Phalcon and jQuery

  • API access (same calls used for machine-to-machine as web users)

    • ValueA frontend framework core components

• Messaging

  • Asynchronous message queueing

    • Using RabbitMQ

• Framework and Services

  • Distributed / scalable task handling

  • Easy to develop services

  • Build-in json schema validation

  • Database access abstraction layers

  • Toolbox for often used tasks, keeping the service footprint to a minimum

• Data storage

  • Relational database + using PostgreSQL

  • NOSQL database + using Apache Cassandra

In the other paragraphs we will describe how communication is processed and how the most important components interact with each other.
