Important
This is a practical selection guide synthesized from Microsoft Learn. For official canonical guidance (which evolves), always verify the linked docs: AI Strategy decision tree and Which Copilot is right for you
- Clarify the goal: productivity in M365 apps, a custom line-of-business agent, or a full-blown AI app/platform?
- Match to service model: SaaS (Copilots) for speed, PaaS (Azure AI) for control, IaaS for maximum customization. Read more about it here Implementation considerations security, data, networking

Note
When users don't want/need to create their own interface or customized view, they can leverage the AI integrated into our products and services, depending on their needs. For example, if they require visualizations capabilities with AI assistance, they can use the AI already built into Fabric/Power Bi to generate reports, ask questions, etc. Click here to read more about it AI Strategy decision tree

| Scenario | Choose | Why this fits | Key notes |
|---|---|---|---|
| Employees want AI in Word/Excel/PowerPoint/Outlook/Teams with enterprise-grade protections | Microsoft 365 Copilot | Natively integrated experiences; work & web chat; governed by M365 controls | Requires org licensing; respects Microsoft Graph permissions. |
| Build a custom agent quickly, connect business data, automate flows, publish to Teams or web | Copilot Studio | Low-code authoring, topics, knowledge sources, agent flows, Power Automate | Great for fusion teams; supports channels via Azure Bot Service. |
| Develop a RAG app or multi-agent solution with fine control over models, evals, safety, and infra | Azure AI Foundry (Azure AI Studio) | Unified SDK/APIs, integrates Azure OpenAI & Cognitive Services, deep ops control | Best for pro-code; aligns with PaaS patterns in CAF. |
| Extend M365 Copilot with task-specific agents using declarative tools | Agents for M365 Copilot (via Copilot Studio & SDKs) | Purpose-built extensions that run inside M365 Copilot orchestrator | See tool comparison & planning guide. |
| Personal, non-sensitive queries with image creation | Microsoft Copilot (consumer) | Free web-grounded assistant | Don’t use for confidential work content. |
| Dimension | Copilot Studio | Azure AI Foundry (Azure AI Studio) |
|---|---|---|
| Audience | Fusion teams, citizen developers | Pro-code developers |
| Approach | Low-code SaaS agent builder with topics, knowledge, agent flows, plugins | PaaS development platform with unified SDKs/APIs, RAG, multi-agent, evals |
| Typical use | Helpdesk bots, HR/IT FAQ, approvals, guided flows, Teams agents | Custom RAG apps, multi-agent orchestration, domain copilots with bespoke logic |
| Data & connectors | Prebuilt/custom plugins, Power Platform connectors; Azure AI Search supported as knowledge | Bring your own data stores; Azure AI Search, vector DBs; full orchestration control |
| Channels | Publish to Teams, web, channels via Azure Bot Service | You host and expose services; integrate into custom apps, Teams, M365 via SDKs |
| Governance | Power Platform governance, DLP, environment controls | Azure governance (RBAC, VNets, Private Link), CI/CD, responsible AI reviews |
| When to pick | Rapid time-to-value; low-code; align with Power Platform ops | Need model choice, fine-grained data/infra control, complex pipelines & testing |
Tip
Need fastest productivity impact across M365?
Choose SaaS (M365 Copilot/Copilot Studio).Building a domain copilot or RAG API with enterprise controls?
Choose PaaS (Azure AI Foundry).Must run in tightly isolated environments or custom GPU stacks?
Choose IaaS.PaaS for speed + control; move edge cases to IaaS if required.

| Dimension |  Microsoft Copilots |
 Azure AI Foundry |
 Self-managed on VMs/Kubernetes |
|---|---|---|---|
| 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 |
| Identity & access | Entra ID + Microsoft Graph; Power Platform DLP | Entra ID (RBAC), Managed Identity, Key Vault, Azure Policy | Your IAM, secrets, RBAC, and policy framework |
| Cost model | Per user/feature licensing | Consumption-based (tokens, search, storage, inference) | Infra + software + ops (VMs/GPU/K8s + licenses) |
| Scaling & ops | Microsoft manages | Azure platform-managed with quotas and SLAs | You provision, scale, patch, monitor |
| Governance & lifecycle | Power Platform environments, DLP policies, solution packaging | Azure Policy/Blueprints, DevOps pipelines, IaC (Bicep/Terraform) | Your SDLC, IaC, change control, audits |
| Risks / trade‑offs | Less deep customization; feature roadmap dependency | Service quotas/limits; more components to secure | Highest ops burden; capacity planning and reliability on you |

It builds
agents(beyond simple chat) that can call flows, connect to data, and act across channels (Teams/web). Please read more about it here Copilot Studio overview
When you need
RAG/multi-agent, model choice, evaluations, and deep integration/testing under your DevOps and networking controls.
Yes, use
agents(declarative) and related SDKs; see the tool comparison and planning guidance. Please read more about here Declarative agents tool comparison, Extensibility planning guide (agents for M365 Copilot).
