SD-WAN Service for Multi-Site UK Businesses

SD-WAN reduces wide area network costs by intelligently routing traffic across multiple connection types, including broadband, 4G/5G, and leased lines. Unlike MPLS, which requires expensive dedicated circuits to every site, SD-WAN uses software-defined policies to prioritise critical applications. The UK broadband average download speed is 69.4 Mbps (Ofcom Connected Nations 2024), and SD-WAN makes effective use of these connections through bonding and quality-of-service controls.

SD-WAN appliances continuously measure the performance of every available connection — monitoring latency, jitter, and packet loss in real time. When one link degrades, SD-WAN automatically reroutes traffic to a healthier path within milliseconds. Business-critical applications such as VoIP and video conferencing are prioritised, while less urgent traffic like software updates can use lower-cost broadband links.

Yes. SD-WAN provides direct cloud breakout at each site, routing traffic to Microsoft 365, Azure, or AWS via the nearest internet exchange rather than backhauling through a central data centre. Microsoft 365 has over 400 million paid commercial seats globally (Microsoft FY2025), making optimised cloud connectivity essential for modern businesses. AMVIA configures application-aware routing to ensure cloud platforms receive priority bandwidth.

MPLS guarantees performance on a private network but is costly and inflexible. SD-WAN overlays intelligent routing on top of any connection type, offering similar application performance at a fraction of the cost. Many UK businesses adopt a hybrid approach, retaining MPLS for latency-sensitive traffic whilst using SD-WAN across broadband and 4G/5G links for general connectivity and redundancy.

SD-WAN appliances can be deployed at each site within two to four weeks when overlaying existing broadband connections, as no new circuit installation is needed. Zero-touch provisioning allows remote configuration from a central controller. Where new leased lines are required, a leased line typically delivers 99.99% uptime SLA (industry standard), but installation takes 45 to 90 working days per site.
