# Layer2C — AI Infrastructure Vendor Assessments

> Layer2C helps enterprise technology leaders evaluate where AI infrastructure vendors actually operate — across compute, data, orchestration, runtime, reasoning, and applications — and where your organization still owns governance, cost, evidence, and accountability.

## What Is Layer2C?

Layer2C evaluates AI infrastructure vendors against the 4+1 Layer AI Infrastructure Model — a framework that maps where decision authority resides across the AI stack. Each vendor component is scored using the Decision Authority Placement Model (DAPM): Retained, Delegated, Ceded, or Absent.

## The 4+1 Layer Model

| Layer | Description |
|---|---|
| Layer 0 | Compute & Network Fabric — GPUs, silicon, interconnects |
| Layer 1A | Data Storage & Governance — storage, metadata, lineage |
| Layer 1B | Context Management & Retrieval — vector search, RAG, retrieval quality |
| Layer 1C | Data Movement & Pipelines — ETL/ELT, KV cache, orchestration |
| Layer 2A | Infrastructure Orchestration — Kubernetes, GPU scheduling, placement |
| Layer 2B | Application Runtime & Execution — model serving, inference, guardrails |
| Layer 2C | Agentic Infrastructure — policy-driven placement, agent governance, evidence capture |
| Layer 3 (+1) | AI Application Layer — applications, ISV ecosystem, business outcomes |

## DAPM Classifications

| Classification | Meaning |
|---|---|
| Retained | Enterprise owns and controls this capability |
| Delegated | Provided by substitutable partner; enterprise retains swap authority |
| Ceded | Vendor controls it; enterprise has no governance authority |
| Absent | No capability exists at this layer |
