ATO-Aware AWS Modernization Without Big-Bang Rewrites

Building modern federal cloud workloads so the authorization boundary, control mappings, and monitoring evidence are outputs of how you engineer — framed against NIST SP 800-37 (RMF) and 800-53. Engineering practice, not a claim of holding an ATO.

• Draw the authorization boundary before you build
• Treat NIST 800-53 control families as design inputs
• Generate ATO evidence from IaC, scan-on-push, and audit logs
• Strangler-fig increments that keep services running
