Modernizing software development environments is crucial for government agencies, particularly those involved in national security, intelligence, and defense missions. The current local machine-based infrastructure is no longer sufficient to meet the demands of AI/ML workflows, which require speed, scale, and security. Centralized, self-managed development environments that operate across unclassified, classified, and air-gapped networks are being adopted by more agencies, offering improved onboarding times, reduced risk, and better control for security and platform teams. These environments support the demands of AI/ML workflows by securely accessing data and compute resources, integrating with specialized tools, and allocating resources dynamically to match compute-heavy workloads. The goal is to build flexible, secure, and scalable platforms that can adapt to mission needs, enabling government software development to deliver secure, reliable software and AI/ML capabilities where they are needed most.
