Description

This is the design blueprints of aktos message passing library for distributed controller systems to build huge systems by following microservices architecture.

Note: This blueprint primarily follows the aktos-dcs-node implementation.

Design Principles

This design is created to match with the following requirements:

• Easy debugging of the distributed system
• Easy re-implementation (in another programming language)
• Provide authentication and authorization layers out of the box
• Easily understandable concepts to adapt new team members rapidly.
• Easily extendable to support new protocols and transports.
