Unified Policy Plane
Branches, data centers, and AWS VPCs in a single operations console with end-to-end visibility.
Network Modernization
Connect Your Enterprise to AWS the Right Way
Enterprise SD-WAN is no longer just about branch connectivity. It's the on-ramp your users, applications, and data take to AWS. We design and deploy SD-WAN architectures that treat AWS as a first-class destination, not an afterthought bolted onto an MPLS replacement.

The Right Architecture
Arista EdgeConnect and AWS Cloud WAN, operated as one fabric
Most SD-WAN deployments treat AWS as an afterthought. We build cloud on-ramp architectures where your branches, data centers, and AWS VPCs appear in a single policy plane.
Most SD-WAN Deployments Were Not Designed for AWS
Most enterprises deployed SD-WAN to replace MPLS and regain control over branch traffic. What they left behind is the gap that has become the dominant problem - AWS was not treated as a first-class destination.
Fragmented operations between SD-WAN and AWS connectivity
Split visibility across vendor consoles
Architectural drift with accumulated exceptions
Manual BGP configurations nobody fully understands
Our Approach
We build cloud on-ramp architectures with Arista EdgeConnect as the primary SD-WAN layer, integrated directly with AWS Cloud WAN and Transit Gateway. EdgeConnect treats AWS regions as first-class SD-WAN segments.
Application-Aware Routing
Optimal path selection whether the target is SaaS, AWS VPC, or on-premises infrastructure.
AWS-Native Integration
Cloud WAN backbone, Transit Gateway aggregation, and Direct Connect with EdgeConnect hosted connections.
How We Deliver
Four-phase approach from assessment to operations handoff.
1
Assessment
Inventory current WAN, existing AWS connectivity, and application traffic patterns. Produce gap analysis and migration risk register.
2
Design
Target architecture covering SD-WAN overlay, AWS network foundation, security integration, and operations model with documented rationale.
3
Deploy
Stage EdgeConnect deployments, stand up AWS Cloud WAN foundation, provision Direct Connect, and execute branch cutovers.
4
Operate
Hand off with full runbooks, transition to Aegis co-managed model, or full managed operations - no project-to-production cliff.
What This Engagement Covers
Complete SD-WAN to AWS integration with unified operations.
SD-WAN Overlay Design
Arista EdgeConnect site architecture, application-aware policy, QoS profiles, high availability topology, and orchestrator configuration.
AWS Network Foundation
Cloud WAN core network design, Transit Gateway attachments, Direct Connect hosted connections, and Route 53 Resolver integration.
Unified Policy and Observability
Single policy plane across sites and AWS VPCs with end-to-end path visibility and monitoring stack integration.
Migration and Cutover
Parallel-run strategy, staged branch migrations, rollback plans, and no-downtime cutover sequencing.
Outcomes
- Single operations plane for SD-WAN and AWS connectivity
- End-to-end application path visibility and control
- Deterministic performance for AWS workloads
- Simplified operations with unified policy management
Ideal Fit
- Ten or more sites running MPLS or first-generation SD-WAN approaching renewal
- Active AWS expansion across multiple accounts or regions
- Direct Connect and SD-WAN environments that need integration
- Organizations evaluating SASE or zero-trust modernization
Platform Selection
Arista EdgeConnect or Cato SASE
Both architectures integrate with AWS Cloud WAN and Transit Gateway. The choice is about how you want security and networking organized operationally.
Recommended
Arista EdgeConnect
Purpose-Built SD-WAN
Best for organizations that need dedicated SD-WAN performance with existing security stack integration.
Best Fit
Choose when you need purpose-built SD-WAN performance, want to integrate with existing security (Palo Alto, Fortinet, Zscaler), have deep Arista investment, or require complex multi-region AWS path control.
Tradeoffs
Requires separate security management and more complex operations across multiple platforms.
Cato Networks SASE
Converged Platform
Best for organizations wanting SD-WAN and security (SWG, CASB, ZTNA, FWaaS) converged on one cloud-delivered platform.
Best Fit
Choose when you want operational simplicity with under 50 sites, are consolidating multiple security vendors, or value single-vendor operations over platform flexibility.
Tradeoffs
Less flexibility for complex routing requirements and vendor lock-in for security functions.
Why IVI
AWS and networking expertise delivered by the same team
Dual Partnership Advantage
AWS Advanced Consulting Partner and Arista Select Partner - we deliver on both sides of the fabric.
Not Just Integration
We're not a networking partner adding AWS or an AWS partner outsourcing SD-WAN. We architect both sides as one unified fabric.
Engineer-Led Delivery
Senior network engineers design and execute deployment with Aegis continuity for ongoing operations.
No Handoffs
The same engineers who build your environment can co-manage or fully manage it under our Aegis operating model.

FAQs
Frequently Asked Questions
Common questions about AWS Cloud On-Ramp services.
How long does a typical SD-WAN to AWS engagement take?
For a mid-market environment with 15-30 sites, expect 10-16 weeks from kickoff to final cutover. Larger or more complex environments extend that timeline proportionally. The first site typically migrates within four weeks of project start.
Can we keep our existing Direct Connect circuits?
Usually yes. We assess each circuit against the target architecture. Some get reprovisioned as hosted connections inside EdgeConnect for deeper integration, some remain as-is, and some are retired in favor of EdgeConnect-delivered paths based on cost, performance requirements, and contract timing.
Do we have to replace our firewalls?
No. Arista EdgeConnect is deliberately designed to integrate with third-party security. If your Palo Alto, Fortinet, or Zscaler deployment is working, we build around it. Firewall replacement is a separate conversation, not a prerequisite.
How does this integrate with our existing SD-WAN?
We regularly migrate from first-generation SD-WAN platforms including earlier VeloCloud deployments, Cisco Viptela, and Silver Peak to Arista EdgeConnect. The migration runs in parallel with the existing fabric, site-by-site, with no flag-day cutover.
What happens to our MPLS contract?
We sequence the migration to align with your contract terms. In most cases, MPLS circuits are retired progressively as sites cut over to SD-WAN, with final contract exit at renewal. We don't recommend taking on early termination penalties unless the business case supports it.
Can IVI manage the environment after deployment?
Yes. Our Aegis Network Operations service provides co-managed or fully managed operations, delivered by the same engineers who designed and deployed the environment. This continuity is a defining feature of how we work.
