Design objective¶
Design Agent365 as an enterprise control plane, not a single agent product. The control plane must provide consistent observability, governance, and security across all participating agent types.
Source: Microsoft Agent 365 documentation.
Reference architecture¶
| Layer | Responsibility | Typical owner |
|---|---|---|
| Experience | End-user agent interaction channels | Product or business teams |
| Agent platform | Agent runtime, orchestration, skills, tools | Platform engineering |
| Control plane | Registry, map, lifecycle, policy templates | AI (artificial intelligence) admin and security governance |
| Identity and policy | Authentication, conditional access, role control | Identity and security operations |
| Data and compliance | Classification, DLP (data loss prevention), retention | Data security and compliance |
| Threat defense | Runtime detection and incident investigation | Security operations center |
Core design decisions¶
- Define control scope: Microsoft-native agents only, or Microsoft plus third-party and custom agents.
- Define trust boundary: what identities can register, publish, and execute agents.
- Define operational boundary: which teams own onboarding, policy, and incident response.
- Define evidence boundary: what telemetry and records are required for auditability.
Deployment model options¶
| Model | Description | Tradeoff |
|---|---|---|
| Centralized | One enterprise Agent365 program and standards board | Strong consistency, lower local autonomy |
| Federated | Shared standards, domain-level execution by business units | Better velocity, higher governance complexity |
| Hybrid | Global mandatory controls with federated delivery lanes | Balanced risk and agility |
Architecture controls checklist¶
- Registry covers every production agent instance.
- Every agent has an accountable business owner and technical owner.
- Identity model is documented for each agent type.
- Allowed data sources and prohibited data paths are defined.
- Security monitoring and incident handoff are documented.
- Runtime and lifecycle actions are constrained by approval policy.
Anti-patterns to avoid¶
- Treating agent control as a one-time inventory project.
- Allowing unmanaged tool integrations without policy review.
- Mixing ownership of build, approve, and audit roles in one account.
- Rolling out enterprise-wide before pilot evidence proves control quality.
Business example¶
A regulated enterprise starts with a federated pilot across finance and customer support. It standardizes mandatory control metadata in Agent365, keeps domain autonomy for implementation, and introduces central review only for high-risk tool access and data-handling changes.
