A ‘secure by design’ foundation built for total control and data sovereignty

A unified cloud platform demands a unified platform team
Industry:
Standardising National Security Infrastructure for Operational Edge

At a glance

A public sector entity was hindered by fragmented, highly customised infrastructures that slowed operational response and increased technical risk. The organisation’s objective was to establish a standardised, ‘secure by design’ private cloud to ensure absolute data sovereignty while accelerating service delivery to the frontline.

The challenge
  • Fragmented, highly customised architectures created by multiple external contractors led to high operational risk.
  • Siloed IT teams (networking, storage, apps) created a ticket bottleneck that hindered rapid completion of time sensitive requests.
  • Critical resource provisioning was an order-taking process taking days or weeks instead of being self-service.
  • Operational security and data sovereignty concerns limited the use of public cloud for sensitive workloads.
The solution
  • Advisory & strategy: Alignment of a 5-year transformation roadmap with the customer’s business strategy.
  • Knowledge transfer: Embedded engineering and structured mentoring to bridge internal skills gaps.
  • Platform transformation: Migration from siloed vSphere to a unified VMware Cloud Foundation (VCF) stack, including NSX, AVI and VKS.
The result
  • Rapid mission response: The provisioning of isolated network segments and resources was reduced from weeks to minutes.
  • Operational independence: In-house teams were transformed into unified platform engineers capable of end-to-end management.
  • Secure-by-design blueprint: A repeatable architecture that satisfies stringent government sovereignty requirements.

The customer

A public sector organisation repsonsible for the handling of huge amounts of sensitive data at speed.

The situation

For over a decade, the organisation relied on project-based delivery where external contractors would stand up unique environments with bespoke architectures and quirks. Once these projects were handed over, the central operations team inherited systems they didn’t fully understand, creating significant risk during outages or when mission critical tasks needed to scale quickly.
Furthermore, the IT model was deeply siloed; end users were often stuck in a chain of dependencies, waiting for multiple teams to coordinate manual changes across physical hardware. This friction acted as a bottleneck to their day-to-day work.

Our approach

Xtravirt moved beyond the role of a typical implementation partner to act as a genuine trusted advisor. The engagement began with deep discovery workshops to understand the real operational friction points across all stakeholder layers – from frontline engineers to senior management. The primary focus was not just on technical delivery, but organisational empowerment.
Xtravirt provided:
  • Expert consultancy: Guiding the transition from legacy vSphere to a modern private cloud operating model with VMware Cloud Foundation.
  • Embedded mentoring: Rather than masking skills gaps with another dependency, Xtravirt embedded the customer’s engineers in the design and build process.
  • Strategic road mapping: Ensuring the VCF platform was built to support future innovations including Private AI and Data Services Manager.

Outcomes achieved

  • From silos to platform engineers: The most significant result was the transformation of the workforce. By involving siloed specialists in the entire journey, Xtravirt helped them remove those siloes and step into broader roles as platform engineers who now manage the environment holistically rather than in isolated components.
  • Empowered internal stakeholders: The move to NSX software-defined networking and VCF Automation has turned IT into an enabler. Tasks that once required coordinating multiple teams over several days can now be handled by a single engineer in minutes, providing individuals with the data they need, when they need it.
  • Sovereign agility: The customer now enjoys a cloud operating model complete with self-service and scalability, without compromising on data ownership. Development teams can build applications in the public cloud and move them to the sovereign on-premises environment by changing only a few lines of configuration.
  • Predictable operational costs: By consolidating onto VMware Cloud Foundation, the organisation has decided against moving to the unpredictable egress charges of public cloud to a flat, predictable bandwidth cost model, allowing for better long-term mission planning.
