Why the cloud layer is the first decision
If your environment uses cloud services for a DoD contract, the cloud layer becomes part of the compliance story. Microsoft’s CMMC guidance explicitly ties contractor cloud usage to ensuring the underlying platform maintains at least FedRAMP Moderate authorization, which is why this page starts with hosting—not with tools.
FedRAMP Moderate authorization vs “Moderate equivalency”
DoD’s FedRAMP Moderate equivalency memo is effectively a “how strict is strict” document. It clarifies that equivalency is not the same as FedRAMP Moderate authorization and sets a high bar: full compliance with the FedRAMP Moderate baseline, assessed by a FedRAMP‑recognized 3PAO, supported by a defined body of evidence.
If your marketing ever mentions “equivalency,” you should also note that the memo disallows POA&Ms resulting from the 3PAO assessment of the cloud service offering; actions must be corrected and validated closed. This matters because it prevents casual “we’ll fix it later” narratives.
When FedRAMP High and DoD ILs show up in architecture
Some workloads require stronger baselines or specific environments. AWS GovCloud (US) documentation positions GovCloud as enabling architectures aligned to FedRAMP High and explicitly references DoD SRG Impact Levels (2, 4, and 5) alongside other defense-relevant compliance regimes (ITAR/EAR). That is the kind of official language you can use as a credibility anchor while remaining vendor-agnostic.
What you should know (safe language)
We design for FedRAMP Moderate (or Moderate-equivalent) cloud foundations when CUI is in scope. This is aligned with Microsoft’s statement about minimum FedRAMP Moderate for underlying platforms and DoD’s memo on equivalency requirements.
Avoid: “Our cloud is CMMC certified.” Microsoft’s guidance is explicit that CMMC is not applicable directly to cloud services in the way certification language implies.
Implementation checklist
- Define the boundary, data flow, and where CUI lives
- Validate cloud authorization status
- Document inheritance vs contractor responsibilities
- Ensure incident response obligations are contract-aligned—because DoD guidance places responsibility on the contractor in relevant scenarios
