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.
