About this opportunity
The Defense Information Systems Agency has awarded contract HC105023D0005 to Amazon Web Services, Inc. on a sole-source basis for the Citadel program, a cloud-based DevSecOps integration platform, under the JWCC contract vehicle on July 30, 2026.
The justification cites FAR 16.507-6(b)(2), establishing that AWS is the only capable source because Citadel's architecture relies on AWS-native microservices and APIs with no operational equivalents among other JWCC cloud service providers. Market research conducted March through July 2026 determined that although Microsoft responded to a competition inquiry, transitioning to Microsoft Azure would require complete re-engineering of the codebase and cross-domain solutions, with an estimated 18 to 24 month re-architecture and re-accreditation timeline that would disrupt mission operations for dozens of 4th Estate partners. The firm-fixed-price task order covers a 1-year base period plus one 1-year option period and one 5-month option period, funded through Operations & Maintenance appropriations. An amendment increased the estimated value due to miscalculation of anticipated growth within the Citadel environment and EC2 service pricing adjustments for the second option period. Price reasonableness is based on comparison to the independent government cost estimate and JWCC Catalog pricing. DISA notes that it is working toward future competition through containerization and Kubernetes modernization efforts to reduce provider-specific dependency.
