You rarely notice the networks that matter most until they stop working. Today's digital world depends on connectivity that simply cannot fail. Think emergency services, industrial sites, smart cities, and large-scale events.
Behind that always-on reality is Citymesh. As a Belgian tech-first telecom operator, Citymesh designs and operates private 5G and hybrid mobile networks in Belgium. They combine IoT connectivity and mission-critical communication solutions for environments where reliability is non-negotiable.
Keeping those networks running requires more than antennas and radio coverage. It demands an IT backbone that scales quietly, recovers instantly, and stays out of the way. That is where Citymesh’s challenge began.
For enterprises and public services in Belgium, Citymesh’s infrastructure underpins some of the country’s most demanding connectivity environments.
The challenge: Telecom infrastructure that had to keep up with innovation
Citymesh’s ambition to push the boundaries of connectivity also placed growing demands on its telecom and IT infrastructure in Belgium. As network services became increasingly software-defined, the underlying compute and storage environment needed to evolve accordingly.
Over time, the existing hypervisor environment had become more complex and required hands-on management, especially around storage. For a highly specialized network engineering team, this introduced unnecessary operational overhead and distracted from core connectivity innovation.
For telecom operators, enterprises, and public services running mission-critical networks in Belgium, infrastructure reliability is not optional.
Citymesh needed an infrastructure platform that was:
- Reliable enough for mission-critical telecom workloads
- Scalable to support rapid growth in private 5G and enterprise networks
- Simple to manage, without requiring deep storage expertise
Most importantly, the infrastructure had to disappear into the background to enable innovation rather than slowing it down. These environments combine high availability requirements with unpredictable demand, leaving little room for downtime or manual intervention.
Choosing the right partner and platform
To modernize its hyperconverged infrastructure in Belgium, Citymesh partnered with Agisko, selecting us for our technical depth, flexibility, and approach to enterprise IT infrastructure.
Unlike large, rigid integrators, Agisko aligned closely with Citymesh’s engineering mindset. The focus was on choosing the right tool for the job, avoiding unnecessary complexity, and ensuring long-term reliability.
During the evaluation phase, Citymesh compared several hyperconverged and infrastructure platforms. Ultimately, Nutanix emerged as the best fit for enterprise mobile networks and industrial workloads.
The decision came down to four critical aspects:
- A mature and proven hyperconverged infrastructure architecture
- Simplified management through integrated compute and storage
- Cost-effectiveness compared to traditional virtualization stacks
- Strong support for the virtual network and appliance-based workloads Citymesh relies on
Unlike traditional virtualization stacks, the new platform removes storage complexity while maintaining full control.
Implementation: Smooth migration with zero operational disruption
The migration to Nutanix ran smoothly from start to finish. Nutanix Move and Agisko’s implementation expertise enabled a seamless transition of workloads with no disruption to operational services.
The new platform provided Citymesh with:
- A streamlined, easy-to-manage telecom infrastructure foundation
- Built-in resilience between datacenters
- The flexibility to scale resources as network and customer demands change
Beyond the initial deployment, Citymesh and Agisko established a hybrid support model, combining proactive maintenance with rapid access to specialized infrastructure expertise when needed.
At the same time, Citymesh invested in internal knowledge. For instance, multiple engineers became Nutanix-certified to ensure long-term autonomy and control.
Results: Reliable infrastructure for mission-critical connectivity
Today, Citymesh operates on an infrastructure designed to do exactly what it should. It runs reliably, scales predictably, and requires minimal day-to-day management.
The platform supports mission-critical telecom infrastructure, where resilience, scalability, and operational simplicity must coexist.
Key outcomes include:
- Always-on performance, even if one datacenter experiences an issue
- Simplified operations through hyperconverged infrastructure, removing the need for manual storage management
- Scalability to support both predictable growth and sudden spikes in demand
- Reduced operational overhead, freeing engineers to focus on connectivity innovation
For a company delivering critical communication services, that kind of reliability is essential, and invisible by design.
A future-proof foundation for what's next
Citymesh’s mission is to turn connectivity into operational value, whether through private 5G networks, industrial IoT platforms, or mission-critical communication systems.
With Agisko and Nutanix as its infrastructure foundation, Citymesh can keep innovating without limits from its IT setup.
The result is a partnership where telecom infrastructure is no longer a bottleneck, but a quiet enabler of everything Citymesh builds next.
