Comparison between Traditional Business Service Layer and Dynamic, SLM-Powered Inference Layer

Abstract

Traditional web application architecture relies on a custom-coded business service layer where logic is explicitly programmed by software engineers. This model, while robust, creates a development bottleneck, making it slow and costly to adapt to changing business requirements. This white paper details a novel architectural paradigm that replaces the static, coded business layer with a dynamic, Small Language Model (SLM) powered Inference Layer.

1. The Architectural Paradigm Shift

The core premise is to decouple business logic from the application code.
