A large U.S. government agency responsible for delivering public services and safeguarding citizen data faced increasing pressure to modernize its legacy IT systems. Its outdated, on-premises infrastructure was limiting innovation, scalability, and cost efficiency—yet the agency’s operations remained mission-critical and subject to rigorous federal security and compliance requirements.
Key Takeaways
- A federal agency managing over $7M in annual cloud spend needed to migrate 9 complex applications to a secure, FISMA/FedRAMP-compliant AWS environment without service disruption.
- Effectual built a multi-account AWS architecture (195 accounts) with a zero-trust security framework and centralized visibility via AWS Security Hub.
- The agency maintained FISMA Moderate compliance throughout migration and achieved "Exceptional" security posture for 10 of 11 months, with a 98% CIO security rating.
- DevOps automation (CloudFormation, Terraform, Jenkins, GitHub Enterprise) streamlined CI/CD and cut deployment overhead.
- Public data access grew from under 1 million to roughly 10 million downloads annually after the migration.
Customer Challenge
The agency needed to migrate its aging infrastructure to a secure, scalable cloud environment without disrupting vital public-facing services. Key requirements included:
- Meeting FISMA Moderate and FedRAMP security compliance
- Migrating nine complex, interdependent applications
- Maintaining uninterrupted service during and after the migration
- Operating across a distributed, multi-account environment with varying workloads
- Gaining visibility into cloud spending while optimizing costs and scaling usage
Balancing modernization, compliance, and operational continuity posed significant challenges for a federal agency managing over $7M in annual cloud spend.
