 1.  **Clarify the goal**: productivity in M365 apps, a custom line-of-business agent, or a full-blown AI app/platform?
-2.  **Match to service model**: **SaaS (Copilots)** for speed, **PaaS (Azure AI)** for control, **IaaS** for maximum customization.\

+|---|---|---|---|
+| Service model fit | Fastest path to value for productivity and common copilots | High control and customization for app/platform copilots | Maximum flexibility for bespoke/regulated builds |
+| Primary use cases | M365 Copilot, Copilot Studio solutions, plugin/Graph-powered automations | RAG apps, domain copilots, tool-use/orchestration, API integrations | Custom model hosting, air‑gapped or non-PaaS constraints, specialized GPUs |
+| Speed to value | Minutes to days | Days to weeks | Weeks to months |
+| Customization depth | Low–medium (prompts, plugins, Graph connectors) | High (Prompt Flow, tools/functions, agents, vector/RAG, custom APIs) | Full stack (models, infra, networking, storage, schedulers) |
+| Model choice | Microsoft-hosted models inside M365 | Azure OpenAI, Azure AI model catalog (OSS/commercial), bring-your-own endpoints | Any model you deploy/manage (open‑source or licensed) |
+| Data readiness & access | Govern via Microsoft Graph permissions, sensitivity labels, Purview; minimize oversharing | Plan grounding stores (Azure AI Search, Cosmos DB, Storage); index and chunking strategy | You design data paths, stores, and indexing end‑to‑end |
+| Networking & isolation | Tenant/Service boundary managed by Microsoft | Private Link, VNet integration, Managed VNets, regional isolation | Full VNet/subnet control, firewalls, proxies, private DNS |
+| Egress control | Built-in guardrails, limited customization | Private endpoints, NSGs, UDRs, forced tunneling; restrict outbound to PaaS | You own all egress/policy controls |
+| Safety & content filtering | Built-in safety filters and enterprise policies | Azure AI Content Safety, safety system prompts, abuse monitoring options | DIY or integrate third‑party safety stack |
+| Compliance & data residency | Inherits Microsoft enterprise compliance in M365 | Choose Azure regions; align with org policies and regulators | Fully your responsibility to implement and evidence |

 ## FAQ
 
 ### Q1. Is Copilot Studio only for chat?
 
-> It builds `agents` (beyond simple chat) that can call flows, connect to data, and act across channels (Teams/web).
