Microsoft Advances Open Standards for Frontier AI Scale

🔧 Microsoft details OCP contributions to accelerate open-source infrastructure for frontier-scale AI, focusing on power, cooling, networking, security, and sustainability. It highlights innovations such as solid-state transformers, a power-stabilization paper with OpenAI and NVIDIA, and a next-generation HXU for liquid cooling. Networking efforts include ESUN and scale-up Ethernet workstreams, while security contributions introduce Caliptra 2.1, Adams Bridge 2.0, and L.O.C.K. The post also advances fleet lifecycle management, carbon accounting, and waste-heat reuse for globally deployable AI datacenters.

Protecting Azure Infrastructure From Silicon to Systems

🔐 Microsoft describes a hardware-to-cloud security approach that embeds verification, isolation, and transparency across Azure infrastructure. The piece highlights purpose-built technologies such as Azure Boost for control-plane isolation, Azure Integrated HSM for server-local key protection, and a spectrum of confidential computing guarantees for workloads. It also emphasizes open-source and ecosystem efforts—Caliptra, OCP SAFE, and a Code Transparency Service—to enable verifiable supply-chain attestations and immutable firmware provenance.
