Why modern connectivity has to be designed, not bolted on

When most enterprise networks were initially architected, they were designed for a world that no longer exists – one where users sat at desks, applications lived in data centres, and the perimeter was something you could point to on a diagram. That world has changed. Yet many organisations are still trying to stretch legacy infrastructure to cover use cases it was never designed for.

The real cost of connectivity failure

The numbers tell a sobering story. IDC research shows that 33% of UK businesses have lost up to £4 million due to network outages or poor performance, with a further 18% experiencing losses exceeding that figure. Following a wave of high-profile IT disruptions throughout 2024 and into 2025, half of UK businesses have been forced to fundamentally re-evaluate their infrastructure. Networking and connectivity has moved to the top of the investment priority list, with 40% of UK businesses naming it their primary technology investment focus for the next twelve months.

Increased spending alone will not resolve the problem, however, if organisations continue to build on bolt-on architecture.

The bolt-on trap

Most enterprise networks evolved rather than being designed. Organisations started with MPLS for site connectivity. Then someone needed cloud access, so direct connections to AWS were added, then Azure, then Google Cloud. Remote workers needed VPN access, so that was layered on. Security appliances were stacked in the path. SD-WAN was implemented to try to make sense of it all. The result is a collection of point solutions, each addressing yesterday’s problem while creating tomorrow’s complexity.

This approach has three compounding problems.

• The first is inflexibility. Every new requirement triggers another procurement cycle, another integration project, another vendor relationship. Research shows that 88% of enterprises believe outdated connectivity infrastructure is actively restricting their ability to leverage technologies like AI. When organisations need to move quickly, waiting months to provision new connectivity is a competitive disadvantage.
• The second is fragmentation. With a network assembled from disparate components, there is no unified view. Teams manage multiple portals, juggle different support contracts, and troubleshoot across vendor boundaries. Nearly two-thirds of European organisations report that network latency and performance issues present a moderate or significant operational challenge – and these problems are often architectural limitations rather than individual component failures.
• The third is the skills burden. The networking skills gap is well-documented: 40% of UK organisations struggle to find or retain networking professionals. When infrastructure requires specialist knowledge across five different vendor platforms, organisations compete for scarce talent while carrying ongoing operational risk.

What designed connectivity looks like

Designed connectivity starts with a different question. Not “what do we need today?” but “what framework will support everything we need over the next three to five years?” This means treating connectivity as a unified fabric rather than a collection of circuits, thinking in terms of capabilities rather than products, and choosing platforms that can adapt as requirements evolve.

Unified management means every connection – whether linking a regional office to a data centre, connecting to Azure, or enabling remote access for a distributed workforce – is visible and manageable from one place. This is operationally critical, not just convenient. When troubleshooting a performance issue, visibility across the entire path matters; not just the segments a particular vendor manages.

Abstracted delivery means teams do not need to care about the underlying transport mechanism. Whether the connection is MPLS, internet, direct cross-connect, or SD-WAN, the platform abstracts those details and presents consistent performance characteristics. The underlying technology becomes an implementation detail, not a management burden.

Rapid provisioning means new sites, new cloud connections, and new services can be made available in hours rather than weeks. When a new cloud region launches or the business acquires a new entity, the network should be able to respond at the same pace as the business requirement.

Built-in intelligence means application-aware routing that adapts to real-time conditions, automatic failover when paths degrade, and telemetry that surfaces problems before users notice them. This intelligence cannot be retrofitted after the fact – it needs to be fundamental to the architecture.

The sovereignty and security dimension

For UK organisations in regulated sectors or handling sensitive data, the location of the network fabric is a material consideration. Many global connectivity platforms route traffic through international hubs, introducing latency, compliance concerns, and data sovereignty questions. A UK-based network fabric with points of presence in key UK data centres ensures traffic stays domestic when required, while still providing international connectivity when needed.

This is particularly relevant when connecting to regulated networks such as HSCN and PSN, where compliance requirements are stringent and there is no margin for architectural ambiguity.

Pragmatic transition

Recognising the limitations of a bolt-on architecture and acting on that recognition are two different things. Modern connectivity platforms are designed to integrate with what already exists. Existing MPLS circuits can connect via VPN. Existing cloud connections can sit alongside new ones during transition. Operating a hybrid environment during migration is normal, not exceptional.

The practical approach is to start with a clear picture of the target architecture and work backwards to a pragmatic transition plan – beginning perhaps with a single use case, such as connecting new sites via the platform while legacy locations remain on existing connectivity, and expanding from there.

Making the business case

The business case for architectural change rests on four arguments.

• Speed to market. When the business identifies an opportunity that requires network presence somewhere new, the question of whether that takes days or months has commercial consequences.
• Risk reduction. The cost of a multi-hour outage, or a security breach stemming from an unpatched legacy component, can be measured. Designed connectivity with built-in redundancy and centralised security policy reduces both the likelihood and the impact of these scenarios.
• Operational efficiency. The initial investment in a proper platform may exceed the cost of adding another point solution, but the ongoing operational picture is different. Consolidating vendor relationships, reducing manual configuration overhead, and simplifying the skills profile required to run the environment all contribute to lower total cost of ownership over time.
• Future-proofing. Technology requirements are accelerating. AI workloads, edge computing, and private 5G are not distant considerations for most organisations – they are near-term planning requirements. An inflexible architecture means constantly catching up; a properly designed platform means being positioned to adopt new capabilities as the business needs them.

Cloud Gateway’s approach

Cloud Gateway’s Business Connect and Business Everywhere solutions deliver unified, scalable connectivity across sites, clouds, users, and data centres through a single, secure platform. New requirements do not trigger lengthy procurement cycles – they are provisioned through the platform already in use. As needs evolve, whether that is scaling bandwidth, adding new cloud connections, or deploying to new locations, the platform adapts without requiring architectural overhauls. For regulated organisations, the same platform supports compliant connectivity to HSCN and PSN alongside private cloud connectivity to AWS, Azure, and Google Cloud.
