When the network goes down, public services stall. In an NHS trust, it can disrupt access to patient records on an A&E ward. For a local council, it could halt the processing of essential benefits. For a police force, it means delayed access to real-time data in the field. In education, it blocks access to learning portals for thousands of students. 

The reliability and security of the network are no longer just IT concerns, they are fundamental to the delivery of front-line public services across the UK. 

Growing Demands on Outdated Foundations 

Public sector organisations are under pressure to digitalise services, improve operational efficiency, and meet the evolving expectations of the citizens they serve. However, many are attempting to build these modern services on network infrastructure that was not designed for today’s demands. 

This creates a cascade of operational risks: 

• Siloed and Complex Systems: Many organisations operate with disjointed network and security architectures, with separate pockets of compute and storage. This legacy complexity makes centralised management, security policy enforcement, and clear visibility difficult to achieve.  

• Increased Reliance on Digital: The sheer volume and velocity of data traffic from modern, cloud-centric applications require a network that can keep pace. Traditional architectures often struggle, leading to performance bottlenecks that impact user experience. 

• An Evolving Threat Landscape: As services become more digital, their attack surface expands, making cybersecurity a primary concern for organisations of all sizes. The security architectures in many data centres have not advanced at the same rate as the network fabrics themselves, leaving them vulnerable.  

• Resource and Budget Constraints: Public sector bodies face the persistent challenge of delivering more with less. They need solutions that reduce appliance sprawl and the associated infrastructure and maintenance costs, while also freeing up valuable IT staff from day-to-day firefighting.  

A New Standard for Mission-Ready Infrastructure 

To meet these challenges, public sector organisations need to move beyond legacy designs. They require a new standard of “mission-ready infrastructure” built on a foundation of modern, data centre networking. This approach is defined by a set of core capabilities designed for the specific pressures of the public mission. 

• Zero Trust Security Built-In: A Zero Trust model is an essential security practice that assumes an attacker is already present in the environment. This means moving security closer to applications by inspecting all east-west traffic within the data centre, applying policies to prevent bad actors from moving laterally across the network.  

• Automation Driven by AI: Manual, reactive processes are no longer viable. The modern network requires automation and AI-powered operations (AIOps) to integrate with cloud platforms, establish and secure connections, and manage the infrastructure. This allows IT teams to automatically detect anomalies and receive actionable solutions, freeing them to focus on high-value activities.  

• Hybrid and Cloud-Ready: Infrastructure decisions must be driven by application and workload placement, not the other way around. A mission-ready network supports a hybrid reality, providing a consistent operational model across on-premises data centres, colocation facilities, and public clouds.  

• Scalable, Consumption-Based Models: To manage budgets and meet sustainability goals, organisations need to move away from cycles of over-provisioning. A flexible, pay-as-you-go consumption model allows for elastic IT, so you only pay for what you use, when you need it.  

How XMA and HPE Aruba Networking Deliver 

As a compliant specialist for the UK public sector, XMA provides the solutions and expertise to build this mission-ready infrastructure, in partnership with HPE Aruba Networking. This is not a theoretical model; the technology is available today. 

The HPE Aruba Networking CX 10000 Series switch, for example, represents a new category of data centre switch. It combines high-performance Ethernet switching with an embedded Data Processing Unit (DPU) to create a distributed services architecture.  

This delivers tangible benefits: 

• Distributed Services at the Edge: Instead of bolting on security appliances, a distributed services switch integrates functions like micro-segmentation, east-west firewalling, NAT, and encryption directly into the network fabric at the top-of-rack. This brings security and services closer to the applications, reducing latency and complexity.  

• Security Without Compromise: This architecture extends Zero Trust deep into the data centre. It provides the scale and performance needed to secure mission-critical workloads without requiring software agents on servers, which frees up valuable CPU cycles for applications.  

• Flexible Delivery with HPE GreenLake: The entire infrastructure can be delivered as a service through HPE GreenLake. This provides a cloud-like experience wherever your applications and data live, with a single contract and a pay-as-you-go model that aligns with public sector budget realities.  

Infrastructure for the Front Line 

• NHS Trust: By distributing security services to the top-of-rack switch, a trust can isolate critical clinical applications and patient data, helping to meet compliance mandates and improving system uptime without adding costly new appliances. 

• Local Council: A council can use a distributed services architecture to securely integrate data between departments, creating a unified platform for citizen services while ensuring strict data sovereignty and access controls are maintained. 

• Police Force: Real-time data sharing from control rooms to frontline officers is critical. A modern, automated network provides the secure, low-latency connectivity needed to ensure this information is available without disruption. 

• University: A distributed architecture provides the ability to micro-segment the network, safely isolating student, staff, research, and operational traffic while delivering secure, high-performance access for a hybrid campus environment. 

Your Mission is Our Focus 

In the public sector, infrastructure is now inseparable from the mission. Outdated networks are no longer a technical debt to be managed; they are a direct risk to service delivery. 

Building a secure, scalable, and automated network is the foundation for a resilient and innovative public service. It is what enables your organisation to meet its objectives, safely and efficiently.
