The Department of Defense, specifically the Air Force Life Cycle Management Center (AFLCMC), intends to issue a solicitation for "Project Marine Duck – CSO Call 5," aimed at acquiring access to an IL-4 cloud environment for modern software development, particularly focusing on C++ development for up to 10,000 users across various DoD entities and contractors. The program emphasizes the need for infrastructure as code, containerization, and scalable onboarding and licensing solutions, with a preference for environments that have recently passed positive security assessments. Interested parties should monitor www.SAM.gov for the solicitation details, as proposals will be accepted only after the Call is posted, and inquiries will be directed to Marina Schemmel at AFLCMC via email at AFLCMC.AFLCMC.GoldenGate@us.af.mil.
