Network & Infrastructure Engineering

Build with clarity.Operate with confidence.

InfraFabric works with clients to understand the requirement, advise on suitable platforms and devices, design the solution, configure and implement it, validate the result and document the environment before handover.

Core capabilities

Engineering focused on the systems that run the environment.

Engagements can cover the full project or a defined phase. The emphasis is on technical discovery, architecture, configuration, implementation, testing and handover.

01 FIREWALLS AND SECURITY

Firewall configuration and secure edge design

Design and configure resilient firewall environments for internet edge, inter-site connectivity, remote access and controlled internal segmentation.

High availabilitySecurity policyNAT and published servicesSite-to-site VPNRemote access VPNSD-WANRouting integrationSecurity profiles
02 SWITCHING AND LAN

Switching, segmentation and resilient LAN design

Configure access and core switching with clear segmentation, resilient uplinks, predictable failover and manageable operational standards.

03 ROUTING AND WAN

Routing and multi-site connectivity

Build routing that is understandable, resilient and appropriate to the scale of the environment, including multi-provider and multi-site designs.

04 SERVERS AND VIRTUALISATION

Server platform configuration

Plan and configure the server services that the network depends on, with attention to resilience, role separation, recoverability and operational clarity.

05 AZURE HYBRID CLOUD

Hybrid cloud and Azure network infrastructure

Design and integrate Microsoft Azure with on-premises infrastructure, covering network architecture, secure hybrid connectivity, routing, security controls, compute and supporting platform services.

06 WIRELESS AND ACCESS

Wireless architecture and access control

Integrate wireless into the wider network and security design rather than treating it as a separate island.

07 STORAGE AND PLATFORM INTEGRATION

Storage and supporting infrastructure

Design supporting platforms around workload, resilience and recovery requirements, then integrate them cleanly with server and network services.

How we work

Start with the requirement, not the product.

InfraFabric can take a project from a blank page or join at a specific stage. The aim is to make technical decisions traceable back to the business requirement and leave the client with a solution they understand.

01

Identify requirements

Understand the business objective, current environment, constraints, dependencies, risks, growth expectations and availability requirements.

02

Advise on vendors, devices and procurement

Compare suitable on-premises and Microsoft Azure architectures, platforms, connectivity options, licensing models and support requirements, then liaise with suppliers or service providers to obtain quotes and help coordinate hardware and connectivity procurement.

03

Design and plan

Create the target architecture, addressing, segmentation, routing, policy model, resilience design, migration sequence, test plan and rollback approach.

04

Configure and implement

Build the required configurations, apply changes in a controlled sequence, integrate services and manage the technical implementation.

05

Validate

Test expected traffic flows, routing, failover, authentication, access policy, service reachability and operational behaviour.

06

Document and hand over

Produce clear as-built information, configuration records, diagrams and operational notes before ownership moves back to the client.

Configuration-led engineering

The configuration is where the design becomes real.

InfraFabric is not limited to producing diagrams and recommendations. The core service is turning the agreed design into working device and server configuration, integrating the components and proving that the environment behaves as intended.

Firewalls

Security and edge

Build high availability, policy sets, NAT, published services, VPN, SD-WAN, security profiles and routing so the edge behaves predictably in both normal operation and failure scenarios.

HAPolicyNATVPNSD-WANIPSRouting

Switches

LAN and segmentation

Configure VLANs, Layer 3 interfaces, trunks, LACP, MLAG, spanning tree, gateway redundancy, access controls, management services and authentication features.

VLANsL3LACPMLAGSTP802.1XNAC

Routers

WAN and route control

Configure dynamic or static routing, route filtering, path preference, provider failover, site connectivity and route exchange with firewall and core environments.

Servers

Core infrastructure services

Configure Windows Server roles and virtualisation platforms including directory services, DNS, DHCP, certificate services, Hyper-V, clustering and supporting infrastructure functions.

Microsoft Azure

Hybrid cloud and network infrastructure

Design and configure Azure networking for hybrid environments, including hub-and-spoke or Virtual WAN architectures, ExpressRoute and VPN connectivity, NVAs, Azure Firewall, Route Server, private connectivity, routing and supporting infrastructure services.

Where InfraFabric fits

Project engineering without forcing the client into a managed-service model.

Use InfraFabric when you need specialist design and implementation capability for a defined infrastructure outcome, whether you already have an internal IT team or simply need additional expertise for the project.

New infrastructureDesign and implement a new environment from requirements through handover.
Refresh and replacementReplace ageing firewalls, switches, routers, servers or supporting platforms.
Migration projectsPlan and execute controlled migrations with defined validation and rollback.
Resilience improvementsRemove single points of failure and improve failover behaviour across the stack.
Design reviewReview an existing proposal or architecture before a client commits to it.
Additional engineering capacitySupport an internal team that needs specialist infrastructure skills for a project.
Documentation and handover

Leave the environment understandable.

A project is not complete when the final change succeeds. The client should know what was built, why it was built that way, how it is connected logically, how it should behave and what information is needed to support it later.
