TL;DR: VDI and DaaS differ most in who controls infrastructure, how scaling happens, and where security responsibility sits, according to Island. For identity teams, the real issue is whether access governance, device trust, and compliance controls remain enforceable when desktop delivery moves into shared cloud operations.
Editorial analysis by NHI Mgmt Group, based on content published by Island: “DaaS vs. VDI: What’s the difference?”.
Key questions
Q: What is the main governance difference between VDI and DaaS?
A: The main governance difference is where control sits.
Q: Why does DaaS change IAM and security accountability?
A: DaaS creates a shared responsibility model, so IAM teams must prove which access, device, and logging controls remain under customer control.
Q: Where do VDI and DaaS most often fail in practice?
A: They fail when governance is treated as a hosting decision rather than a control design decision.
Practitioner guidance
- Clarify the responsibility split before migration Document which desktop controls remain customer-owned and which are provider-owned, especially authentication, device trust, logging, patching, and compliance evidence.
- Map desktop governance to identity controls Review whether access approvals, conditional access, and session policy can still be enforced consistently when desktops are delivered through a shared cloud service.
- Test scaling against entitlement discipline Check whether faster desktop provisioning creates inconsistent access reviews, excessive standing access, or unmanaged exceptions during onboarding and seasonal expansion.
Bottom line: VDI preserves more direct organisational control, but that control only helps if the team can operationalise patching, scaling, and policy maintenance consistently.

VDI versus DaaS is an identity governance question disguised as an infrastructure choice. The article correctly shows that the operational difference is not only where desktops run, but who can enforce policy across identity, devices, and compliance. Once desktop delivery crosses into a shared service model, access governance becomes less about owning the stack and more about proving control across boundaries. Practitioners should evaluate desktop architecture as part of identity control design, not as a separate IT procurement decision.
A question worth separating out:
Q: How should teams evaluate VDI versus DaaS for compliance?
A: Teams should compare how each model supports evidence, data residency, access logging, and policy enforcement. VDI offers more direct control, but the organisation must sustain it. DaaS may simplify operations, but compliance depends on provider guarantees and on whether the customer can still enforce identity and configuration requirements consistently.
