Overview

Windows Server 2025 Datacenter is Microsoft's latest long term servicing channel server operating system, built on the 24H2 platform with hotpatching, GPU partitioning, SMB signing by default and TLS 1.3 for LDAP. This image runs it preconfigured for AWS with Desktop Experience.

Why the cloudimg image

cloudimg ships a Windows Server 2025 Datacenter with CloudWatch, Systems Manager, EC2Launch v2, enhanced networking and IMDSv2 already installed and configured, so it is operational from launch. Every subscription includes 24/7 Windows Server and AWS experts with a guaranteed 24 hour response SLA.

Common uses

  • Active Directory and IIS
  • AI workloads with GPU partitioning
  • Windows containers

Key features

  • 24/7 Windows Server and AWS experts with guaranteed 24-hour response SLA and average 1-hour response for critical issues. Unlike AWS Basic Support, cloudimg covers OS-level troubleshooting including Active Directory, IIS, security hardening, and AWS service integration - so your team gets specialized help day or night without hiring in-house Windows expertise.
  • Production-ready in minutes: Pre-configured CloudWatch Agent, Systems Manager Agent, EC2Launch v2, ENA networking, NVMe storage, and IMDSv2 security. Unlike the stock Windows Server AMI, this image ships with AWS tooling already installed and configured - eliminating manual setup and reducing your time from launch to operational workload.
  • Windows Server 2025 LTSC with hotpatching to reduce planned maintenance windows, GPU partitioning for AI workloads, SMB signing by default, TLS 1.3 for LDAP, and extended Microsoft support until November 2034. Built on the 24H2 platform (build 26100) Datacenter edition with Desktop Experience.

Description

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

Product Overview

Windows Server 2025 Datacenter AMI with 24/7 expert support from cloudimg. This is Microsoft's latest Long Term Servicing Channel (LTSC) release, built on the 24H2 platform (build 26100), with extended support until November 2034. Pre-configured with AWS native tooling for monitoring, automation, and secure management - ready for production in minutes, not hours.

Why Choose This AMI Over the Standard Windows Server AMI?

The free AWS-provided Windows Server 2025 AMI gives you a vanilla OS. This cloudimg AMI delivers a production-ready environment with pre-installed and pre-configured AWS tooling (CloudWatch Agent, Systems Manager Agent, EC2Launch v2, ENA drivers, NVMe optimization, IMDSv2 security) plus dedicated 24/7 Windows Server experts who understand both the OS and the AWS platform. When you hit an issue at 2 AM - whether it is Active Directory replication, IIS configuration, security hardening, or AWS integration - cloudimg's team responds within 24 hours (average 1 hour for critical issues). AWS Basic Support does not cover OS-level troubleshooting; cloudimg does.

Key Features and Buyer Outcomes

  • Hotpatching: Apply many security updates without a reboot, reducing planned maintenance windows and keeping workloads available. On-premises requires Azure Arc and VBS; a quarterly baseline cumulative update still reboots.
  • Enhanced Security: SMB signing required by default, configurable SMB over QUIC, Credential Guard, VBS, TLS 1.3 for LDAP, and Delegated Managed Service Accounts (dMSA) to mitigate credential theft.
  • GPU Partitioning (GPU-P): Share a physical GPU across multiple VMs with live migration support for AI, ML inference, and graphics workloads.
  • AWS Integration: EC2Launch v2, CloudWatch Agent, AWS CLI v2, SSM Agent, ENA networking, NVMe storage, IMDSv2 - all pre-installed and configured.
  • Active Directory Scalability: Opt-in 32KB page size (up from 8KB) for larger, more complex directory environments.
  • Containers: Windows Containers with HostProcess containers and Kubernetes integration.
  • Storage: Storage Spaces Direct, ReFS deduplication and compression, NVMe performance.
  • .NET Support: Full .NET Framework backwards compatibility plus .NET and ASP.NET Core.
  • Long-Term Support: Mainstream until November 2029, extended until November 2034.

Example Use Case: Mid-Market Enterprise AD Migration

A 200-seat professional services firm consolidating three on-premises Active Directory domain controllers onto EC2. Using this AMI, the IT team deploys two m6i.large instances as domain controllers with the 32KB AD page size enabled, leverages hotpatching to maintain 99.9% uptime without scheduling monthly reboot windows, and relies on cloudimg's 24/7 support for domain trust configuration and Group Policy troubleshooting. The result: reduced maintenance overhead, eliminated hardware refresh cycles, and expert assistance available around the clock.
