Delivering on the Promise of OneGov: Federal Agencies Modernize with OneGov — and AWS Expands its Program to ISV Partners

In August 2025, Amazon Web Services (AWS) secured a OneGov agreement with GSA, to provide up to $1 billion in savings to accelerate cloud adoption, modernization, and training across the federal government. Less than a year later, agencies and partners are leveraging this program to make meaningful progress on cybersecurity and cloud migrations.

Here’s a small sampling of the progress we’ve made together.

Agency Modernization Progress Under OneGov

Centers for Medicare & Medicaid Services (CMS)

• Next Generation Desktop (NGD): Through their work with GDIT, CMS is migrating their customer relationship management (CRM) system from legacy on-premises data centers to AWS and upskilling their workforce via AWS Training. The NGD system supports CMS’s beneficiary-facing contact center, which receives over 37M contacts annually from Medicare and Health Insurance Marketplace beneficiaries. This migration supports ongoing modernization efforts for systems that serve Medicare and Health Insurance Marketplace beneficiaries.
• Payment Error Rate Measurement (PERM): Through GDIT, CMS is migrating their State Medicaid error rate findings system to AWS to support modernization efforts and future system enhancements. The migration supports continued modernization of systems used in Medicaid program administration.
• AWS Outposts for Critical Infrastructure: CMS is utilizing AWS Outposts as part of its hosting environment for critical and sensitive workloads across its data centers. AWS Outposts provides capabilities intended to support organizations seeking to leverage cloud-based infrastructure while meeting stringent security requirements for data residency and isolation. This initiative supports CMS modernization efforts involving infrastructure management and hosting environments.
• Enterprise Contact Center: Through GDIT, AWS is modernizing legacy infrastructure to migrate the CMS enterprise IT HelpDesk to Amazon Connect. This effort supports modernization of contact center infrastructure and administration.
• Medicare Administrative Contractor (MAC): Through their work with GDIT, CMS is consolidating multiple legacy MAC contact centers to Amazon Connect Customer to modernize and streamline healthcare provider inquiries into Medicare while training their workforce on the use of Amazon Connect Customer. The MAC contact centers receive nearly one million calls annually to request support for Medicare claims submissions and inquiries. This modernization effort is intended to support contact center operations through enhanced communications capabilities and more consistent workflows.

General Services Administration (GSA)

• Cloud Ecosystem: GSA IT is modernizing and migrating their technology portfolio with AWS, including mainframe, robotic process automation (eRPA), telecom ordering management, and award management system workloads. The project includes foundational modernization initiatives that will establish critical AI and data capabilities across all migrated workloads. This first tranche kicks off as part of a multi-year transformation program for GSA.

Small Business Administration (SBA)

• Multi-Data Center Migration: Through Four Points, AWS is migrating multiple data centers supporting the SBA’s Office of Capital Access, Office of the Chief Financial Officer (OCFO), and Office of the Chief Information Officer (OCIO). The scope includes four data center exits, modernization of critical applications, and establishing a full business disaster continuity and recovery (BDCR) solution for SBA’s key financial systems. Implementation is underway with an expected September 2026 final deployment.

National Oceanic and Atmospheric Administration (NOAA)

• National Centers for Environmental Information (NCEI) Data Center Migration: AWS ProServe won the bid to partner with NOAA NCEI—the world’s largest provider of environmental data—to execute one of its most ambitious infrastructure modernizations. The engagement encompasses migrating approximately 1,000 virtual machines and up to 20 petabytes of environmental data from on-premises data centers to an AWS FedRAMP Moderate cloud environment, while maintaining zero downtime across approximately 300 active data streams. Beyond the initial migration, AWS and NCEI are modernizing legacy archival systems to cloud-native S3-based storage solutions and optimizing complex applications for long-term scalability. The result: NCEI harnesses AWS’s global cloud to better serve scientists, researchers, and the public worldwide with faster, more secure access to data, all while meeting federal data center exit mandates.

Bringing ISV Partners into the Framework

AWS is expanding the program to include Independent Software Vendor (ISV), partners giving federal agencies streamlined access to the AWS-native SaaS solutions that power their most critical missions. This strategic expansion accelerates governmentwide IT transformation by pairing the cloud savings AWS already delivers with the application-layer software agencies need most, eliminating fragmented procurement cycles and enabling modernization at unprecedented speed and scale. By bringing in the ISV community, AWS is equipping federal agencies to retire legacy systems faster, adopt advanced AI capabilities, and deliver better services to the American people while maximizing value for the taxpayer.

What’s Next

The momentum behind OneGov reflects a broader shift in how the federal government approaches technology: moving from fragmented, agency-by-agency procurement to a unified strategy that delivers better outcomes at lower cost. AWS is committed to delivering results on its OneGov agreement and supporting the GSA, federal agencies, and ISVs across government to make this transformation a reality.
