Leidos secures $454.9m contract to modernise USAF Cloud One platform

Leidos secures $454.9m contract to modernise USAF Cloud One platform. Leidos will partner with AWS, Azure, Google Cloud, and Oracle to modernise the US Air Force's multi-cloud environment. Leidos has secured a $454.9m contract to upgrade the US Air Force's Cloud One platform, a central technology resource supporting mission-critical operations across the Department of Defense (DoD). The initiative involves collaboration with major cloud service providers, including Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, and Oracle Cloud Infrastructure. The project aims to enhance the security and automation of the platform while streamlining operations and reducing costs for Air Force teams managing cloud environments. According to Leidos, these improvements are expected to facilitate quicker management of cloud operations and simplify the adoption and scaling of cloud services across additional Air Force units. The Cloud One programme aims to accelerate cloud adoption throughout the Air Force globally, bolster cyber defences, and support operational readiness. Leidos digital modernisation division president Steve Hull said: "Modernising Cloud One helps the Air Force deploy mission-critical operations faster and defend them more effectively. It also creates a secure, repeatable cloud foundation that other Department of War organisations can adopt, helping to remove barriers to cloud adoption and enabling teams to move faster and more securely to help meet mission demands and maintain a strategic edge."
