Arista + VeloCloud: A New Era for Enterprise SD-WAN

Rethinking SD-WAN for the Next Wave of Enterprise Demands

Most enterprises have already left behind the era of rigid MPLS backbones and migrated to SD-WAN as their foundational WAN architecture. For many, that first-generation SD-WAN deployment delivered major cost savings and performance flexibility—but now, the game has changed again.

“As hybrid work, multi-cloud, and AI workloads reshape traffic patterns, enterprises are evaluating their first or second SD-WAN refresh—not just for cost savings, but for scale, observability, and security integration.”

Initial SD-WAN architectures solved for branch-to-cloud connectivity, but they weren’t designed for the ‘any-to-any’ reality of today’s enterprise: distributed apps, edge AI, remote users, and cloud-native services that span continents and providers.

Enter Arista VeloCloud—a modern SD-WAN fabric reimagined for this next wave. It delivers:
    •    Cloud-native scale
    •    App-aware dynamic path optimization
    •    Zero-touch provisioning
    •    Deep telemetry and integration across the full enterprise network stack

“VeloCloud isn’t just an MPLS replacement anymore—it’s a platform built for the operational and architectural agility today’s enterprises require.”

What Is Arista VeloCloud?

Arista VeloCloud is a cloud-delivered SD-WAN platform that intelligently steers application traffic across any combination of transport links (broadband, LTE, MPLS), while delivering assured performance, centralized control, and flexible edge security.

This isn’t just a rebranding. With Arista’s acquisition of VeloCloud from Broadcom (2025), two powerhouses have joined forces:
    •    VeloCloud, a pioneer in SD-WAN and Dynamic Multipath Optimization (DMPO), and
    •    Arista Networks, the market leader in data center, cloud, and campus networking.

Together, they form a client-to-cloud networking fabric that finally dissolves the historical boundaries between LAN, WAN, and cloud.

“The Arista VeloCloud fabric is engineered to provide high performance from branch to cloud, with deep visibility, policy automation, and end-to-end telemetry—all delivered through a unified platform.”

Key Architectural Advantages

Disaggregated Architecture

Control, data, and management planes are separated for massive scalability and resilience.

VeloCloud Orchestrator (VCO): Central cloud-based control and policy management
VeloCloud Gateways (VCG): Global cloud access nodes with native peering to SaaS/IaaS
VeloCloud Edge (VCE): On-prem and virtual appliances with deep app awareness and path intelligence

“A single orchestrator can manage thousands of edges—across branch, cloud, and remote user environments—with no bottlenecks or single points of failure.”

Dynamic Multipath Optimization (DMPO)

VeloCloud’s DMPO is a major differentiator. It:

Monitors link performance in real time (latency, jitter, loss)
Makes sub-second, per-packet forwarding decisions
Aggregates bandwidth across multiple circuits
Remediates degraded paths using FEC and NACK mechanisms

“DMPO isn’t just for failover—it actively boosts performance for real-time apps and aggregates multiple circuits to act as one.”

Zero-Touch Provisioning and Operational Simplicity

Deploying a branch site can take minutes, not hours or days.

Ship a pre-configured Edge
Plug in power and WAN
Device auto-authenticates, downloads config, and starts forwarding traffic

“With IVI’s codified onboarding process, we’ve helped customers bring hundreds of sites online in a matter of weeks—with minimal onsite resources.”

Flexible Edge Security with Open Integration

VeloCloud includes:

Stateful L7 firewall
Segment-based policy enforcement
Native ZTNA-like app access for remote users
IPsec overlay encryption

But what sets it apart is its open model for SASE:

Easily integrate with Zscaler, Netskope, or Palo Alto Prisma Access
Choose your own SSE vendor for Secure Web Gateway, CASB, DLP

"VeloCloud is perfect for organizations that want to build a best-of-breed security stack—not be locked into a rigid all-in-one.”

SD-WAN vs. SASE: What Path Makes Sense?

For many organizations, the decision is not binary. True SASE platforms like Cato offer fully integrated networking + security in one software stack. But they require a shift in operating model and centralization of security control.

Arista VeloCloud offers a more modular, flexible path:

Ideal for orgs where NetOps and SecOps are distinct teams
Enables integration with existing security investments
Prioritizes network performance and visibility over bundled security

“IVI helps customers make this decision based on architecture, security maturity, and operational readiness—not vendor hype.”

Future Roadmap Under Arista: What to Expect

Arista’s roadmap signals tight integration between:

VeloCloud SD-WAN
CloudVision telemetry and analytics
EOS switching and routing stack

This means enterprises can expect:

Unified configuration and monitoring from campus to WAN
Streamlined policy enforcement across fabric domains
Improved automation, visibility, and DevOps support

“The long-term vision is clear: a unified, API-first operating model across all network domains, without compromise.”

Let’s Talk Architecture - Not Just SKUs

We help customers cut through marketing noise and evaluate what fits their real-world needs:

Is VeloCloud the right fit for your topology and scale?
Are you ready for a full SASE transition or a phased hybrid model?
How do you maximize the ROI of your existing MPLS, SD-WAN, or firewall investments?

Let’s design the right WAN for your future—together.
