Global connectivity is now a strategic capability for multi‑site factories, not just an IT concern. Arista VeloCloud SD‑WAN, delivered as-a-service by Digital Carbon, gives manufacturing IT leaders a single, resilient fabric to connect plants, warehouses and cloud platforms worldwide while retaining full visibility and control.
The connectivity challenge for multi‑site factories
Modern manufacturing runs on real‑time data: ERP and MES, quality systems, industrial IoT, AI analytics and cloud services all need low‑latency, predictable connectivity between plants and regions. When a network link underperforms, dashboards lag, robots stop, and production SLAs are at risk.
Traditional MPLS and single‑circuit VPNs were never designed for this level of agility or global reach. They are expensive, slow to provision, and rigid when you need to open, relocate or integrate factories across continents, especially after mergers and acquisitions.
Where legacy WANs hold you back
In many manufacturing organisations, each plant still negotiates its own connectivity contracts, resulting in a patchwork of ISPs, technologies and SLAs. IT teams then have to manage dozens of point solutions with limited end‑to‑end visibility across the estate.
This fragmentation makes it hard to guarantee performance for critical applications such as MES, SCADA, or real‑time quality monitoring. It also complicates security and incident response, because policies and logs are scattered across multiple platforms and providers.
Why SD‑WAN manufacturing strategies matter
SD‑WAN manufacturing strategies replace that patchwork with a software‑defined overlay that sits above any combination of broadband, dedicated fibre, MPLS, 4G/5G and satellite links. The overlay continuously monitors loss, latency and jitter, steering traffic over the best available path in real time to meet application needs.
This is why more manufacturers are actively comparing sd wan providers instead of defaulting to carrier‑managed MPLS. The right sd wan solutions can turn commodity internet circuits into an enterprise‑grade WAN, with centralised control and built‑in security that is far easier to adapt as your footprint evolves.
Arista VeloCloud: a global fabric for factories
Digital Carbon’s platform is built on Arista VeloCloud SD‑WAN, which provides a cloud‑delivered WAN with zero‑touch deployment, one‑click business policies, advanced firewalling and a comprehensive analytics dashboard. VeloCloud edges at each site establish encrypted tunnels across all available links, creating a single virtual WAN regardless of local access technology.
Dynamic Multipath Optimisation (DMPO) continually measures each path and applies techniques such as forward error correction, packet duplication and jitter buffering. In tests, this has increased usable bandwidth on variable‑quality links by up to 90% for voice and up to 650% for video, which is critical as factories adopt more vision systems and AI analytics.
Cloud gateways and direct internet access
A key advantage of VeloCloud versus many other sd wan vendors is its global cloud gateway architecture. Thousands of cloud gateways, deployed in over 30 regions and close to major SaaS and IaaS platforms, act as a low‑latency on‑ramp from each factory to the cloud.
Branch edges build overlays to these gateways and can aggregate multiple WAN circuits to maximise throughput and stability. DMPO then protects SaaS and IaaS traffic all the way from the factory’s last mile to the “doorstep” of providers like Microsoft 365 and AWS, ensuring consistent performance even when individual ISPs experience degradation.
This architecture underpins secure direct internet access from every site, so cloud traffic can go directly to its destination rather than hair‑pinning through a central data centre. For IT leaders, that means better user experience for cloud ERP and collaboration tools, lower backhaul costs, and a simpler, more scalable design.
Building resilience and redundancy into the network
Manufacturing cannot tolerate extended downtime: a single circuit failure can stop production lines, disrupt logistics and impact customers. VeloCloud SD‑WAN is engineered for high availability through active‑active link aggregation and automatic failover.
Multiple circuits—fibre, broadband, and where needed 4G/5G or satellite—are treated as a single logical pipe. If latency spikes or loss increases on one path, the overlay can steer priority traffic elsewhere in milliseconds, often before users notice an issue. This is especially important as AI‑driven and upload‑heavy workloads become more common on the plant floor.
With a coherent sd‑wan manufacturing design, you can also standardise redundancy patterns globally: for example, dual local ISPs plus a wireless backup in every plant, with policies enforced centrally instead of bespoke designs per site.
Visibility, control and security for OT and IT
For IT leaders, global connectivity is as much about governance as it is about bandwidth. VeloCloud’s cloud‑based orchestrator gives a single pane of glass for application performance, link utilisation, ISP behaviour and user experience across every factory and warehouse.
From there, you can define application‑aware policies—such as prioritising MES and SCADA traffic, rate‑limiting software updates during shifts, or throttling non‑business traffic—then push them instantly to all locations. This centralised model reduces configuration drift and makes it far easier to prove the impact of network changes to operational stakeholders.
Security is integrated rather than bolted on. Each edge includes a stateful, context‑aware firewall, supports segmentation and micro‑segmentation between OT and IT networks, and establishes automatic site‑to‑site VPNs for secure mesh connectivity between factories, warehouses, data centres and cloud environments. This directly addresses rising OT cybersecurity risk as plants become more connected.
How Digital Carbon’s co‑managed model changes the game
Many manufacturers hesitate to move to modern sd wan solutions because they fear losing control to opaque managed services, or overloading small central IT teams with another complex platform. Digital Carbon addresses both concerns with a co‑managed approach.
You retain full access to the SD‑WAN and security consoles—visibility, policy control, analytics—while Digital Carbon handles design, deployment, tuning, vendor management and 24/7 escalation as an extension of your team. This means you are not locked out of your own infrastructure, but you also do not need to become deep experts in every dial and feature before seeing value.
On the connectivity side, Digital Carbon sources global broadband, direct internet access, 4G/5G and low‑orbit satellite from a network of trusted partners, so you deal with one provider rather than dozens of local carriers. Every solution is optimised for performance and security from day one, regardless of geography.
Aligning with AI‑driven and Industry 4.0 roadmaps
Research into AI‑driven enterprises shows that SD‑WAN has evolved into a critical toolkit for handling high‑bandwidth, low‑latency and often bursty data flows associated with AI and advanced analytics. As manufacturers adopt computer vision, predictive maintenance, digital twins and agentic AI, networks must support more uplink‑heavy and peer‑to‑peer traffic between edge, data centres and multiple clouds.
Modern sd wan vendors such as Arista VeloCloud provide the application identification, dynamic path selection and emerging AIOps capabilities needed to keep these workloads performing reliably. For manufacturing IT leaders, this means your WAN becomes an enabler for AI initiatives rather than a bottleneck or afterthought.
Choosing the right SD‑WAN manufacturing partner
There is no shortage of sd wan providers on the market, but very few combine deep Arista VeloCloud expertise with a truly co‑managed model and global connectivity reach. Digital Carbon focuses specifically on multi‑site, fast‑moving businesses and has built its services around SD‑WAN, SASE, ZTNA and global connectivity for exactly these scenarios.
Instead of selling a generic “managed service”, Digital Carbon runs structured workshops to understand your current environment and objectives, demonstrates the platform in action, and then supports a proof of concept over three to six months so you can see tangible improvements in latency, resilience and visibility before a wider roll‑out. This de‑risks the transition away from legacy MPLS and point‑to‑point VPNs.
Next steps: book a workshop with Digital Carbon
If you are responsible for networking or infrastructure in a manufacturing business with multiple plants or a growing global footprint, now is the time to review whether your WAN can keep pace with Industry 4.0 and AI initiatives. Ask yourself:
-
Do we have a consistent global design, or a patchwork of circuits and contracts?
-
Can we prioritise MES, ERP and OT traffic across all sites with central control?
-
How quickly can we integrate a newly acquired plant into our network?
-
Do we have clear, real‑time visibility into application performance and ISP behaviour everywhere?
If any of those answers feel uncertain, a focused sd‑wan manufacturing workshop is a straightforward way to explore options.
Digital Carbon offers engaging, vendor‑agnostic workshops where we map your current environment, highlight where sd wan solutions and secure direct internet access could add immediate value, and outline a proof‑of‑concept tailored to one or two priority factories.
