Introduction

For hybrid use cases using Microsoft Windows Server 2025, both on-premises and Azure: Get crucial updates with less downtime. Hot patching allows many security updates to be applied without rebooting. An add-on service is available for Azure Arc-enabled servers.

Features

• Hotpatch: Security updates with no reboot (available for Azure Arc-enabled servers) and multi-layered security; secured-core server technology: Trusted Platform Module 2.0 and systemguard.


• Active Directory (AD): LDAP support for TLS 1.3 helps remove obsolete cryptographic algorithms; Kerberos support for AES SHA256/384; new domain controllers increased to 32K pages; added RootDSE mod.


• WAC for hybrid and on-premises server management; containers extension in WAC; decreased size of WS core container base; simplify containerizing .NET, ASP.Net, Web Deploy, and MSI applications.


• Hyper-V: GPU partitioning (GPU-P) allows to share a GPU across multiple VMs; support for live migration and failover clustering; VM scalability: Support for 240 TB of RAM; support for 2048 LPs.


• Storage Migration Services: Optimized NVMe; lower CPU utilization; software-defined storage enhancements: Resilient File System (ReFS)-optimized deduplication and compression.


• Seamless management of hybrid server environments, storage migration, system insights, protecting VMs, synchronizing file servers, and providing enhanced Active Directory authentication.
