A large civilian agency needed to exit two aging data centers and achieve FedRAMP High authorization under a Congressional deadline. 340+ workloads. 18 months. No schedule slippage.
A civilian agency operating under a Congressional IT modernization mandate was running 340+ production workloads across two on-premises data centers with hardware contracts expiring inside 24 months. Two prior cloud migration attempts had stalled before completing the FedRAMP authorization process, leaving the agency no closer to compliance and burning program budget.
The agency engaged Ingress via GSA MAS IT-70 with one hard constraint: FedRAMP High ATO and full data-center exit within 18 months, or face Congressional reporting consequences.
The agency's prior migration attempts failed for the same reason: compliance was treated as a downstream activity rather than a parallel workstream. Each time, the team reached the SSP authoring stage, found control gaps that required infrastructure rework, and collapsed the timeline. The institutional memory of two failures made internal stakeholders skeptical that a third attempt would succeed.
The workload environment compounded the problem. 340+ applications ranged from simple web portals to latency-sensitive backend systems with undocumented cross-dependencies. Migrating them in the wrong order would cascade failures. And the deadline was statutory, not a preference that could be renegotiated.
The decisive architectural choice was treating FedRAMP package authoring as a concurrent workstream from day one. Every infrastructure decision had a control reference. Every code commit was potential evidence. No surprises at assessment time.
Every workload migrated within the 18-month window. FedRAMP High ATO was issued on schedule, with the 3PAO citing the SSP documentation quality as among the highest reviewed in a recent civilian agency engagement. The parallel authoring approach meant there were no control gaps discovered at assessment time that required infrastructure rework.
Year-over-year infrastructure costs dropped 42% following data center exit, driven by right-sizing, reserved instance commitments, and elimination of two facility leases. Zero security incidents occurred during the full 18-month migration period, including the parallel-operation window when workloads were split across environments. The agency's internal cloud operations team was trained, documented, and running independently before Ingress rolled off.
