Secure Hybrid Infrastructure

Secure Hybrid Infrastructure

with Windows Server 2025, Hyper-V, and Azure Local

Practical administration, security, virtualization, and resiliency for real enterprise environments.

Windows Server administration has moved beyond server maintenance. Today’s infrastructure teams are expected to secure privileged access, manage hybrid estates, automate routine work, troubleshoot under pressure, and keep critical services available across local and cloud-connected platforms. This 4-day program focuses only on the most important operational areas: Windows Server 2025 advanced administration, hybrid management with Azure Arc, security hardening, Windows Admin Center, Hyper-V, Failover Clustering, Azure Local, and disaster recovery.

The course is designed to be practical and scenario-based, not introductory or academic. The instructor has over 30 years of industry experience and will use real industry-demanded content aligned with enterprise infrastructure operations. Microsoft’s current guidance highlights Windows Server 2025 hybrid features, Azure Arc integration, hotpatching, Windows Admin Center, Azure Local cloud-based deployment and monitoring, and secure management as key areas for modern Microsoft infrastructure.

Learning Outcomes

By the end of the training, participants will be able to:
