Fragmented infrastructure limits defense operations

The Danish Department of Defense managed a distributed IT landscape spanning three primary datacenters and numerous server rooms and local installations across Denmark. For a defense organization requiring rapid-response capabilities and operational resilience, this fragmented environment imposed critical limitations.

The environment was distributed across the country, complex to secure, and costly to maintain, limiting agility and operational visibility. Each installation maintained its own infrastructure, creating inconsistent security postures, duplicated administrative effort, and reduced ability to rapidly deploy and scale defense applications.

“We needed infrastructure that could support modern defense operations—scalable, highly available, and secure by design,” explains a Danish Defense IT leader. “The distributed server rooms model was increasingly unsustainable from both operational and security perspectives.”

As part of Microsoft’s Dynamic Datacenter initiative, the Defense IT organization partnered with Cohort leadership (then part of Microsoft Services) to pilot what would evolve into Azure Stack and Azure Local. This collaboration offered a unique opportunity to modernize defense infrastructure by applying emerging cloud principles while maintaining the sovereignty and security requirements essential to defense operations.

Pioneering hybrid cloud for defense

Cohort leadership helped architect and deploy an early infrastructure-as-a-service (IaaS) model using Microsoft System Center and Hyper-V, creating a unified, policy-driven private cloud. This was among the first defense implementations of what would become Azure’s hybrid cloud architecture.

The modernization program centered on four key pillars:

• Infrastructure Consolidation – Rationalized datacenter workloads and migrated distributed servers into three centralized, virtualized facilities with high availability and shared capacity. This consolidation dramatically reduced the physical footprint while improving resilience.
• Automation and Management – Implemented System Center for orchestration, provisioning, and monitoring, enabling on-demand resource allocation and self-service capabilities that accelerated deployment timelines from weeks to hours.
• Security and Compliance – Integrated Active Directory and Group Policy for identity, encryption, and access control, aligning with defense cybersecurity requirements. Established unified security policies across all virtualized infrastructure.
• Cloud Alignment – Delivered an architecture modeled on early Azure design principles, forming the foundation for future adoption of Azure Stack and Azure Local. This forward-looking approach positioned Danish Defense for seamless cloud evolution.

According to the Defense IT team,

“Cohort’s expertise in both Microsoft technologies and defense requirements was invaluable. They helped us navigate uncharted territory, implementing cloud-like capabilities years before commercial solutions were available.”

From distributed complexity to centralized agility

The infrastructure modernization delivered transformative improvements across operational efficiency, security, and strategic capability. The program successfully consolidated dozens of decentralized server rooms into three managed data centers, dramatically simplifying the IT landscape and improving service delivery.

Infrastructure footprint and administrative overhead were reduced substantially while availability increased significantly. The virtualized, centralized model enabled higher utilization rates, eliminated redundant infrastructure, and freed IT personnel from routine maintenance to focus on strategic initiatives.

Security posture and policy compliance improved across Defense IT operations through unified identity management, standardized security controls, and centralized monitoring. The organization could now enforce consistent security policies across all infrastructure rather than managing dozens of independent installations.

Perhaps most significantly, Danish Defense established one of the first Azure-aligned hybrid environments in Europe, years ahead of commercial Azure adoption. This early implementation yielded valuable insights that informed both Azure Stack development and defense cloud strategy among NATO partners.

“The transformation exceeded our expectations,” the Defense IT leader reflects.

“We didn’t just consolidate infrastructure – we fundamentally changed how Defense IT delivers capability. The agility and security improvements have proven essential for modern defense operations.”

A foundation for next-generation defense capabilities

With the hybrid cloud infrastructure in place, Danish Defense operates a modern, policy-driven environment that enables rapid capability deployment while maintaining the security and sovereignty requirements essential to defense operations. The organization has established architectural patterns and operational practices that will allow continuous modernization.

For defense and government organizations facing similar infrastructure challenges, the lesson is clear: early adoption of emerging technologies—when executed with the right expertise—can deliver strategic advantage. The key is partnering with teams that understand both the technology and the unique requirements of defense operations.

“Being an early adopter comes with challenges, but the benefits have been substantial,” advises the Defense IT leader. “We gained years of cloud infrastructure experience, influenced technology development, and established a foundation that continues to serve Danish Defense well. Organizations that wait for perfect solutions often fall behind—strategic partnerships enable you to shape the future rather than simply adopt it.”
