Design Principles of Microservices: AKF Scalability Cube, Front‑End/Back‑End Separation, Stateless Services, and RESTful Communication
This article explains core microservice design principles—including the AKF scalability cube with its Y (functional), X (horizontal scaling), and Z (data partition) axes, front‑end/back‑end separation, stateless service architecture, and RESTful communication—providing practical guidance for building scalable, maintainable systems.
