Jan 1, 2026January 2026 monthly summary for NHSDigital/dtos-manage-breast-screening. Focused on strengthening hybrid connectivity and scalable onboarding of Arc-enabled servers to support enterprise deployments, while mitigating deployment risks through controlled gating and identity safeguards. Delivered end-to-end Arc-enabled server onboarding with Azure Relay namespace deployment and private endpoints, including feature-flag controlled deployment and conditional provisioning. Extended infrastructure modules to support Azure Relay Hybrid Connection for secure on-premises communication, with proper authorization rules configuration. Fixed deployment blockers caused by insufficient managed identity privileges by disabling Arc-enabled servers in review/dev environments pending identity remediation. Overall, these changes enable scalable, secure connectivity between Azure and on-prem workloads, reduce deployment risk, and establish a robust foundation for future Arc-based operations.
