Transit Connectivity
Hub-based architecture using AWS Transit Gateway, Azure Virtual WAN, or CloudEOS overlay patterns.
Cloud Networking
Multi-Cloud Networking That Actually Works
Most organizations didn't plan to be multi-cloud—they became multi-cloud by accretion. AWS for infrastructure, Azure for Microsoft 365, acquisitions bringing GCP. The result is often disconnected cloud islands without coherent networking architecture.
IVI designs multi-cloud network architectures that provide reliable connectivity, consistent security enforcement, and unified visibility across cloud platforms and on-premises infrastructure.
Enterprise networking discipline applied to multi-cloud environments.
A Different Approach
Transit architecture that spans clouds and connects to on-premises
Rather than managing bilateral connections between every pair of environments, we design hub-based, cloud-native, or overlay-enabled architectures that provide any-to-any connectivity with consistent enforcement.
The Multi-Cloud Challenge
Multi-cloud environments by accretion create specific networking challenges that single-cloud architectures don't face.
Traffic between clouds routes over public internet with unpredictable latency
Security policies don't span platforms automatically
Observability goes dark when traffic crosses cloud boundaries
Compliance frameworks require consistent controls across all environments
Multi-Cloud Network Architecture
IVI designs transit architectures with consistent connectivity and security layers that span cloud platforms.
Consistent Security
Palo Alto VM-Series with Panorama management for unified policy across all environments.
Unified Observability
LogicMonitor-based monitoring that spans cloud platforms and on-premises infrastructure.
How It Works
Six-phase approach from assessment through operational integration.
1
Multi-Cloud Assessment
Document current cloud environments, identify connectivity gaps, security inconsistencies, and observability blind spots.
2
Architecture Design
Design transit connectivity, per-cloud networks, security enforcement, and observability architecture with honest tradeoffs.
3
Foundation & Security Deployment
Deploy connectivity foundation, security enforcement layer, and validate cross-cloud performance and failover behavior.
Key Capabilities
Comprehensive multi-cloud networking capabilities delivered through the engagement.
Multi-Cloud Connectivity Architecture
Transit VPC/VNet design, inter-cloud connectivity, routing design, and CloudEOS overlay where appropriate.
AWS and Azure Network Architecture
VPC and VNet design with security groups, route tables, NAT architecture, and cloud-native services integration.
Arista CloudEOS Integration
Virtualized network extensions in AWS and Azure for consistent routing and segmentation with data center infrastructure.
Outcomes

FAQs
Frequently Asked Questions
Common questions about multi-cloud networking architecture and implementation.
We're primarily AWS but need to support Azure workloads. How do we architect for two clouds without doubling complexity?
A hub-based transit architecture is the right foundation. AWS Transit Gateway for your AWS environment, Azure Virtual WAN or hub VNet for Azure, and secure interconnect between them is often the starting point. For organizations wanting tighter integration with enterprise networks, Arista CloudEOS can extend routing and overlay constructs into the cloud.
Can we extend our on-premises Palo Alto firewall policies to cloud environments?
Yes. Palo Alto VM-Series firewalls deployed in AWS and Azure, managed through Panorama alongside your on-premises PA-Series, provide unified policy frameworks. App-ID, URL filtering, and threat prevention profiles remain consistent across on-premises and cloud environments.
Where does Arista CloudEOS fit in a multi-cloud design?
CloudEOS fits where organizations want more control and consistency in routing, overlay design, and hybrid cloud operations. It's especially attractive for customers already standardized on Arista in the data center who want to extend familiar operational models and network constructs into AWS and Azure.
We have AWS Direct Connect and Azure ExpressRoute separately. Should they be integrated?
Having both is a starting point, but many organizations route inter-cloud traffic over the internet rather than through private connections. We design routing architecture to use your private connections efficiently and architect failover appropriately for both performance and security.
How does multi-cloud networking interact with our SD-WAN deployment?
IVI designs SD-WAN to cloud gateway integrations that extend your VeloCloud environment to cloud platforms. This means branch locations can have optimized, policy-driven connectivity to cloud workloads using the same SD-WAN platform you're already operating.
What observability challenges exist in multi-cloud environments?
Cloud-native monitoring tools provide visibility within each platform but go dark when traffic crosses cloud boundaries. We deploy LogicMonitor-based observability that covers VPC flow logs, cloud gateway health, inter-cloud path performance, and application traffic flows across your entire hybrid footprint.
