AWS or Google Cloud for a Federal or Defense Contractor's Systems

Before touching infrastructure, get precise about what the contract and any applicable DFARS clauses actually require, whether that's a specific FedRAMP authorization level, CMMC certification level, or ITAR handling for export-controlled data. This isn't a cloud platform question yet, it's a contract compliance question, and the answer narrows your infrastructure options before you compare AWS and Google Cloud at all.

AWS GovCloud is a long-established, physically and logically isolated region built specifically for government workloads with a deep track record among defense contractors. Google Cloud's Assured Workloads takes a different approach, layering compliance controls and data residency guarantees on top of its standard regions rather than a fully separate physical environment. For a contractor new to this space, AWS GovCloud's longer track record and larger base of contractors who've already built on it often means more available guidance and staff who've done it before; Google Cloud's approach can be a reasonable fit if your team is already deep in its ecosystem for other reasons.

Standing up and maintaining a compliant environment takes real, dedicated operations expertise, and a median salary of $105,770 for a general operations manager role is a useful anchor when budgeting for this properly rather than assigning it as a side responsibility to someone already stretched thin¹. Contractors that treat this as a part-time addition to an existing role are the ones who struggle to maintain compliance once the initial setup work is done.

Federal contracts often specify incident response timelines, and your failed deployment recovery time, how fast you can restore service after a bad change, is part of demonstrating you can meet those timelines, not a separate engineering concern². Build and test that recovery process before you need it under a real incident review, rather than describing it in a policy document nobody has actually exercised.

Run a tabletop exercise at least twice a year where your team walks through an actual simulated failure, timing how long restoration genuinely takes rather than assuming the documented procedure would work under pressure. Contractors that only discover gaps in this process during a real incident, or worse, during an assessment, lose credibility they don't easily get back.

Write down the actual time it took in each exercise and compare it against what your contract or internal policy claims, then close the gap deliberately rather than quietly adjusting the policy language to match whatever the last drill happened to produce.

In this scenario, the contractor picked AWS GovCloud, largely because two of their engineers had prior experience with it from a previous employer and their prime contractor on this award already ran there, which meant fewer new integration questions during onboarding. That's a reasonable, common way this decision actually gets made in practice: existing team experience and a prime contractor's existing environment often outweigh a feature-by-feature comparison.

Confirm your specific FedRAMP authorization level and CMMC requirements directly with your contracting officer or a qualified compliance consultant rather than inferring coverage from a cloud vendor's general compliance marketing, since a vendor's platform level authorization doesn't automatically mean your specific configuration on top of it meets your contract's requirement.

Confirm these points with your contracting officer or a qualified compliance consultant:

• The exact FedRAMP authorization level and CMMC requirements that apply to this specific contract.
• Whether your particular configuration is covered, since a vendor's platform level authorization does not automatically extend to what you build on top of it.
• Whether any ITAR-controlled or CUI data is involved, and how the contract says it must be handled.
• Whether your prime contractor's platform is a contractual requirement or just the more convenient default.

Contractors new to CUI handling frequently underestimate how much of the total contract budget the compliance buildout itself consumes, separate from the ongoing hosting cost. Get a specific estimate from a compliance consultant or your prime contractor's own experience before you bid the next contract, rather than treating this year's buildout cost as a one-time expense that won't recur. Every new authorization boundary or system added later typically needs its own slice of this work.

Standing up a compliant environment is the easier half of this work; keeping it compliant as your contract portfolio grows and staff turns over is the harder, ongoing half. Schedule a recurring internal review, not just the periodic external assessment, so configuration drift gets caught by your own team before an assessor finds it. Contractors who treat compliance as a one-time project rather than an ongoing discipline are the ones who fail a reassessment they assumed they'd already passed for good.
