How a federal program gets productive inside a government shared cloud such as Cloud One, cArmy, a JWCC task order or cloud.gov: platform selection, onboarding, tenant configuration, and a control inheritance workbook built for the SSP.
Most federal programs no longer choose whether to use the cloud. They are told which one. DoD components direct programs toward enterprise environments such as the Department of the Air Force's Cloud One and the Army's cArmy, and toward commercial cloud bought through the Joint Warfighting Cloud Capability (JWCC). Civilian agencies steer programs toward agency enterprise clouds, GSA's cloud.gov, and FedRAMP-certified shared offerings. These platforms exist so that a program office does not have to engineer and secure its own cloud.
Getting onto one is still real work. Someone has to pick the right platform for the program's data and impact level, get the funding document and intake forms through without losing a place in the queue, configure the program's tenant inside the platform's guardrails, connect identity and network paths, and write down which security controls the platform covers and which the program still owns. Most program offices do not have spare people for any of that.
This paper is written for the people who carry that problem: program managers and mission owners with a deadline, the component CIO or cloud program office that set the direction, the ISSM or ISSO who has to defend the authorization story, and the contracting officer who buys the help. It describes Avalon Technology Services' Gov-Shared Cloud Services:
The work is sold as a fixed-fee sprint of three to ten weeks, or as the first workstream of a larger migration. Section 8 compares two paths for a representative program. In that illustration, building a bespoke cloud environment costs $1.01M more over three years than onboarding to the enterprise platform, before counting the 6 extra months the program waits to become productive.
A directed move to a shared platform looks like a paperwork exercise from above. From inside the program office it carries four kinds of risk.
| Risk | How it shows up |
|---|---|
| Mission | A system stuck on aging infrastructure, or waiting months in a platform onboarding queue, cannot deliver capability. Directed-migration deadlines slip and the program absorbs the blame. |
| Compliance | Mission owners often assume the platform's authorization covers them. It does not. The mission system still needs its own authorization, and inheritance that is not documented reads as unmet controls at assessment time. |
| Cost | Programs that bypass the shared environment and open their own cloud accounts pay twice: once for duplicate engineering, and again when an IG or cost review flags the duplication. Consumption billed through a platform with no tagging or chargeback model becomes spend nobody can see. |
| Operational | A tenant configured around the platform's guardrails instead of within them breaks at the next platform update. Identity and connectivity shortcuts turn into outages and findings later. |
"The platform has an ATO, so we're covered" is the single most expensive misunderstanding in shared cloud. The platform's authorization covers the platform. Under the NIST Risk Management Framework, the mission system is still its own system with its own boundary, and its Authorizing Official still makes their own decision. What the platform offers is a set of controls the program can inherit, provided the program documents that inheritance control by control. FedRAMP makes the same distinction in its 2026 Consolidated Rules: it now calls a qualifying offering "FedRAMP Certified," while agencies still authorize their own use.
The demand behind these triggers is growing. DISA reported more than $3.9 billion in JWCC task orders by late 2025, with the Air Force onboarding and large Army orders the year before. Every new task order is a program that still has to get productive inside the environment it bought.
The first question is not how to onboard but where. The answer depends on the program's data, impact level and mission, not on which platform is most familiar. The fit assessment inventories the program's workloads and data types (CUI, PII, PHI and classification level) and scores each candidate environment against the same criteria.
| Candidate environment | Typical fit |
|---|---|
| JWCC task orders (commercial cloud through DISA) | DoD programs buying AWS, Google, Microsoft or Oracle capacity directly |
| Department of the Air Force Cloud One | Air Force and Space Force programs; broader DoD use where supported |
| Army cArmy | Army programs directed to the enterprise environment |
| Department of the Navy environments | Navy and Marine Corps programs, including Flank Speed-adjacent work |
| DISA Stratus | DoD workloads suited to DISA's on-premises cloud |
| VA Enterprise Cloud | VA health and benefits systems |
| GSA cloud.gov | Civilian applications that fit a FedRAMP-authorized platform-as-a-service; small agencies without a cloud team |
| FedRAMP-certified shared SaaS and shared services | Commodity functions an agency should buy rather than host |
Each candidate is scored on five criteria: support for the required impact level, the controls the program can inherit, the cost model, onboarding lead time, and exit terms. The result is a recommendation with a written decision record, so the program can defend the choice to its CIO, its assessor and its budget office. Sometimes the honest answer is that no shared environment fits, and the program needs its own architecture. The assessment says so.
| Activity block | What Avalon does |
|---|---|
| 1. Platform fit and selection | Inventory workloads and data types, score candidate environments, and recommend a destination with a decision record. |
| 2. Onboarding execution | Drive the platform's intake end to end: sponsor and funding coordination (MIPR or interagency agreement), account and enclave requests, impact-level determination support, region selection, and every intake form, submitted correctly the first time. |
| 3. Tenant landing-zone configuration | Inside the platform's guardrails: account structure, segmentation, connectivity path, identity federation, logging hookup, tagging standard, and baseline infrastructure-as-code where the platform permits it. |
| 4. Control inheritance mapping | Reconcile the platform's authorization against the mission system's NIST SP 800-53 control set: inherited, shared and program-owned, control by control. |
| 5. Governance and handoff | Consumption and chargeback model, service-request runbook, roles and permissions, exit and portability notes, and a working-session handoff to program staff. |
| Deliverable | Format |
|---|---|
| Platform Fit and Selection Assessment, with scoring matrix and decision record | Report plus scoring workbook |
| Onboarding runbook and completed intake artifact set | Document plus copies of submitted platform artifacts |
| Configured tenant landing zone | Live configuration plus infrastructure-as-code repository where the platform allows customer-managed code |
| Control Inheritance Workbook | Spreadsheet mapped to NIST SP 800-53, structured for direct SSP import |
| Connectivity and identity integration design note | Diagram plus short design document |
| Governance, tagging and chargeback standard | Document plus tag dictionary |
| Handoff briefing | Slides plus a recorded working session |
| Not included | Where it belongs instead |
|---|---|
| Migrating or refactoring the applications | Cloud Migration & Development; this service ends at a tenant-ready state against a written acceptance checklist |
| Designing a bespoke, agency-owned cloud | Cloud Architecture & Engineering, when the fit assessment concludes no shared environment fits |
| Writing the full SSP or running the ATO process | System Security Plans and ATO Process Facilitation; the workbook is an input to both |
| Steady-state operations and monitoring | Enterprise Monitoring or a separate O&M arrangement |
| Cloud consumption | Bought by the agency through the platform's vehicle; Avalon resells nothing and marks up nothing |
| Historical cost audit and recovery | FinOps |
Inheritance is where shared cloud either pays off or quietly fails. A platform's authorization lets a tenant inherit some controls completely, share others, and leaves the rest entirely with the program. The Customer Responsibility Matrix published with the platform's authorization says which is which in general terms. It does not say how those responsibilities apply to one specific mission system.
The Control Inheritance Workbook closes that gap. For every control in the mission system's baseline, it records whether the control is inherited, shared or program-owned, what evidence supports that position, and who on the program owns the remaining work. It is built for the ISSO, and it is formatted so rows can move directly into the System Security Plan.
Stated precisely: this effort positions the program to inherit the maximum defensible set of controls from the platform's authorization and documents the remaining mission-owner responsibilities in an assessor-ready Customer Responsibility Matrix reconciliation.
| Framework | What this service addresses |
|---|---|
| NIST SP 800-53 Rev. 5 and RMF (SP 800-37) | Control-by-control reconciliation across families such as AC, AU, CA, CM, IR, SC and SI. Speeds the RMF Prepare, Categorize, Select and Implement steps by using the platform as a common control provider. The Authorize step remains the AO's. |
| FedRAMP | Verifies the destination offering's certification status and class, and documents the agency's use of it. FedRAMP's 2026 Consolidated Rules use "FedRAMP Certified" with classes A through D. |
| DoD Cloud Computing SRG | Impact-level determination support and verification that the destination holds a DISA provisional authorization at the required level. |
| FISMA | Defines the mission system's boundary inside the shared environment, a frequent point of assessor confusion. |
| DoD Secure Cloud Computing Architecture (SCCA) | Connectivity through Cloud Access Points and SCCA components, so the tenant's network path is compliant by construction. |
| DoD Zero Trust Strategy | Maps which zero trust activities the platform delivers and which the tenant must implement ahead of the FY2027 target-level deadline. |
| TIC 3.0 (civilian) | Aligns the tenant's connectivity to the applicable CISA TIC 3.0 use case. |
| ICAM (OMB M-19-17) and HSPD-12 | CAC and PIV-based identity federation into the tenant. |
Avalon does not issue Authorizations to Operate, DISA provisional authorizations or FedRAMP certifications, and does not guarantee any authorization outcome or timeline. Platform authorizations belong to the platform's authorizing officials, and the mission system's authorization rests with the agency's AO. The onboarding, configuration and inheritance work is readiness and advisory work: it makes the authorization achievable and defensible, and it is not the authorization itself.
Every shared platform publishes guardrails: the account structures, network patterns, identity providers and logging paths its tenants must use. Tenant configuration works within those guardrails. Configuration that works around them may go live faster, but it breaks at the next platform update and damages the program's relationship with the platform office.
Sold on its own, the service is a three-to-six week fit assessment and onboarding sprint. Tenant configuration and the inheritance workbook add time when the destination is already decided, for a total of four to ten weeks. Inside a Cloud Migration & Development engagement, it is the first two-to-six week workstream, completed before any workload moves.
Duration depends on impact level and the number of enclaves far more than on the size of the agency. An IL5 enclave with SCCA connectivity work takes weeks longer than an IL2 tenant or a civilian FedRAMP Moderate tenant.
| Role | Involvement |
|---|---|
| Cloud solutions architect (founder-level) | Leads delivery at 50–75% |
| Cloud and platform engineer | About 50% |
| Compliance specialist | About 25%, focused on the inheritance workbook |
Platform queue time is the one schedule driver Avalon does not control. Every agency- and platform-dependent step goes into the statement of work with a date and an owner, with schedule relief tied to those dates:
| Offering | Typical price (firm fixed price) | Duration |
|---|---|---|
| Shared cloud fit assessment and onboarding roadmap | $25K–$75K | 3–6 weeks |
| Onboarding execution, tenant configuration and inheritance workbook | $60K–$175K | 4–10 weeks |
| Inside a Cloud Migration & Development engagement | A fixed line item, typically 10–20% of the migration's services value | First 2–6 weeks |
These are market-norm planning ranges, validated against the specific program before any figure appears in a proposal.
Firm fixed price is the default because the work is bounded and deliverable-defined. When integration unknowns are high, such as an unusual identity architecture or a contested connectivity path, a small time-and-materials allowance can cover the configuration block while the rest stays fixed. Cost goes up with IL5 scope and SCCA connectivity, multiple enclaves or cloud providers, and cleared-staff requirements. It goes down for IL2 or civilian FedRAMP Moderate destinations and when the destination is already decided.
GSA's OneGov agreements have put cloud credits in agency hands. The AWS agreement, for example, offers up to $1 billion in incentive credits across civilian agencies through December 31, 2028. These credits generally fund consumption and provider-delivered support, not independent tenant-side work, but onboarding correctly is how a program actually uses them.
This is an illustration, not a quote and not a result. It compares two paths for one representative unclassified program over three years. Cloud consumption is the same in both paths and is left out. Every input is listed in Appendix C.
| Cost line | Build your own environment | Onboard to the enterprise platform |
|---|---|---|
| One-time engineering and setup | $420K | $165K (Avalon fixed fee) |
| One-time authorization work | $350K (no inherited controls) | $150K (program-owned controls only) |
| Annual operations staff | $330K (2 FTE) | $165K (1 FTE) |
| Annual continuous monitoring | $120K | $50K |
| Annual contract or platform fees | $40K (separate cloud contract) | $90K (platform service fee) |
| Year 1 total | $1.26M | $620K |
| Three-year total | $2.24M | $1.23M |
| Months until productive | 9 | 3 |
What the comparison shows
| Scenario | Year 1 difference | 3-year difference | Time saved (value) |
|---|---|---|---|
| Base case | $640K | $1.01M | 6 months ($720K) |
| Platform service fee doubles ($180K a year) | $550K | $740K | 6 months ($720K) |
| Weaker inheritance (program-owned work $250K; monitoring $90K a year) | $500K | $790K | 6 months ($720K) |
| Platform queue adds 3 months (6 months to productive) | $640K | $1.01M | 3 months ($360K) |
| Building your own costs 30% less | $409K | $779K | 6 months ($720K) |
Onboarding stays cheaper in every scenario tested, but the size of the advantage depends on how much the platform really lets the program inherit and what the platform charges tenants. Both are measured during the fit assessment for the actual candidate platforms. When no shared environment supports the program's impact level or mission, the comparison does not apply, and the assessment says so.
| ID | Risk | Likelihood | Impact | Mitigation built into the plan |
|---|---|---|---|---|
| R-1 | Platform intake queue or funding document stalls the schedule | High | High | Every agency and platform step dated in the SOW with an owner; schedule relief tied to those dates |
| R-2 | Scope drifts into migrating the applications | Medium | High | End state defined as a tenant-ready environment against a written checklist; migration priced separately |
| R-3 | Inheritance claimed but not documented | Medium | High | Control-by-control workbook with evidence references, reviewed with the ISSO before handoff |
| R-4 | Configuration conflicts with platform guardrails | Medium | Medium | Configuration built from platform-provided modules and reviewed against published guardrails |
| R-5 | Identity federation or connectivity approval takes longer than planned | Medium | Medium | Design note agreed with the network and identity owners in week one; small T&M allowance where unknowns are high |
| R-6 | No one owns the environment after handoff | Medium | Medium | Roles, runbook and handoff session in the base scope; operations owner named at kickoff |
| Vehicle | Fit for this service | Avalon's access |
|---|---|---|
| GSA Multiple Award Schedule, SIN 518210C | The natural home for a standalone sprint; agencies can issue a small fixed-price order quickly | Avalon's priority vehicle |
| NASA SEWP VI | Contract period starts November 1, 2026; Categories B and C cover services, and all categories support small business set-asides | Near term, as a subcontractor to Category B or C holders |
| GSA Alliant 3 | Large modernization task orders where this service is one line item | Subcontractor to awardees |
| OASIS+ | Services orders where the parent engagement is broader modernization | On-ramp candidate |
| JWCC | Compute is bought from the cloud providers; tenant-side help is bought separately | Market context, not a contracting path |
| Agency and component BPAs, small business set-asides | The sprint is sized as a BPA call | Direct |
Onboarding existing systems is usually funded with one-year O&M money, which is why demand peaks in the fourth quarter. Programs tend to plan the buy between April and June and need it awardable in days between July and September. A fixed-fee sprint with defined deliverables is a clean fit for that window. A system still in development may fund the same work with RDT&E.
| Pitfall | How the plan prevents it |
|---|---|
| "While you're in there, migrate the app" | The SOW defines the end state as a tenant-ready environment and says that workload migration is separately scoped |
| "Also fix our rogue accounts" | Remediating environments built outside the platform is priced as an option, never absorbed |
| Compliance oversell | No claim that the platform's ATO covers the program, that an impact-level decision is an authorization milestone, or that the workbook is the SSP |
| Agency-side delays read as vendor failure | Every dependent step is dated in the SOW, with schedule relief when those dates slip |
| Code the program cannot maintain | Infrastructure-as-code built on platform modules and handed off in a working session |
| No exit plan | Exit and portability notes in the base scope, for the platform's next recompete |
| Next step | Why it follows onboarding |
|---|---|
| Cloud Migration & Development | The tenant is ready; the applications still have to move |
| System Security Plans and ATO Process Facilitation | The inheritance workbook feeds the SSP and the assessment directly |
| FinOps | The tagging and chargeback standard makes cost governance possible |
| Enterprise Monitoring | Someone has to run and watch the environment after handoff |
| Zero Trust Architecture | The platform-versus-tenant zero trust map becomes the program's implementation plan |
Several dates shape the demand. SEWP VI opens for orders on November 1, 2026. The AWS OneGov credits run through December 31, 2028. DoD's target-level zero trust deadline falls at the end of FY2027. DISA has been preparing a follow-on to JWCC. Each of these pushes more programs into shared environments that they will need help onboarding onto.
Shared cloud platforms remove the need for every program to build its own cloud. They do not remove the need to get onto them correctly. A program that picks the right platform, onboards without rework, configures within the guardrails and documents its inheritance control by control reaches a productive, defensible environment months sooner, and walks into its assessment with evidence instead of assumptions.
The first step is a fixed-fee shared cloud fit assessment. It scores the candidate platforms against the program's data and impact level, prices both paths, and lays out a dated onboarding plan. Avalon takes on one onboarding engagement at a time, at unclassified scope (IL2, IL4 or civilian FedRAMP Moderate), with founder-level attention on the work.

A simplified example of how the Control Inheritance Workbook classifies controls for a tenant on a shared IaaS platform. Actual classifications depend on the platform's authorization and customer responsibility matrix.
| Control | Typical position | What the program still documents or does |
|---|---|---|
| PE-3 Physical Access Control | Inherited | Reference the platform's authorization; no program action |
| AC-2 Account Management | Shared | Program accounts and roles, reviews, and federation to the agency identity provider |
| AU-6 Audit Record Review | Shared | Review of tenant logs; platform provides collection and storage |
| CM-6 Configuration Settings | Shared | Settings for the program's workloads within platform baselines |
| IA-2 Identification and Authentication | Shared | CAC or PIV federation for program users |
| SC-7 Boundary Protection | Shared | Tenant segmentation and allowed flows; platform provides the perimeter and CAP or TIC path |
