High-Performance Multi-Cloud Networking

Optimize Application Performance While Moving Workloads Between Cloud Platforms

The Multi-Cloud Reality

Most enterprises today don't live in a single cloud. Workloads are spread across Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) — driven by best-of-breed services, data sovereignty, regulatory requirements, mergers, or simply the pace of digital transformation. But while multi-cloud delivers flexibility, it introduces a critical challenge: How do you connect these environments securely, reliably, and cost-effectively?

Native cloud interconnects and point-to-point VPNs are expensive, operationally complex, and difficult to scale. They lack intelligent traffic management, leave security policy fragmented, and can't adapt dynamically to changing application demands. The result is higher costs, degraded performance, and a growing attack surface.

The Multi-Cloud Networking Challenge

Traditional approaches to connecting cloud environments — static VPNs, expensive MPLS extensions, and manual peering — cannot meet the demands of modern, distributed enterprises. Organizations need a smarter, unified fabric that spans all major cloud providers without sacrificing security or performance.

The Hararei Solution: SD-WAN Powered Multi-Cloud Fabric

Hararei brings over 8 years of SASE and SD-WAN deployment experience to solve multi-cloud networking. Leveraging HPE Aruba EdgeConnect — one of the industry's most advanced SASE/SD-WAN platforms — Hararei delivers a secure, automated, and intelligent networking fabric that spans AWS, Azure, GCP and on-premise environments simultaneously.

EdgeConnect's virtual overlay technology abstracts the underlying transport — whether that's internet broadband, cloud provider interconnects, 4G/5G mobile or private circuits — and creates a unified, policy-driven network across all cloud environments.

With real-time insight into network and application health, AI-driven network adaptation and automated fault isolation, users will experience the perfect WAN!. Advanced SD-WAN features can perform packet-by-packet routing to address underlying network brownouts, and TCP mitigation to address high-latency network issues

Key Capabilities

Multi-Cloud Fabric: Unified connectivity across AWS, Azure, and GCP from a single management plane
Intelligent Traffic Routing: Dynamic path selection based on application performance, cost, and availability
End-to-End Security: Full traffic encryption across all inter-cloud links, with IDS/IPS at the branch and cloud edge
Cost Optimisation: Replace expensive MPLS and cloud provider premium interconnects with broadband and SD-WAN overlays
Rapid Deployment: Automated provisioning of new cloud sites and regions in minutes, not weeks
Centralised Observability: Granular visibility into application performance, latency, and traffic flows across all clouds
Support Disaster Recovery: Provide protection against supplier risk, location risk and soverign risk Disaster Recovery Scenarios
Cloud Migration & Exit: Provide optimised WAN connectivity whether your workloads are moving to, exiting or between Clouds. Provides a cost-effective mechanism to move bulk data

Reference Architecture

Hararei designs inter-cloud SD-WAN architectures tailored to each customer's environment. The following illustrates a typical multi-cloud deployment:

Environment	Architectural Elements
AWS (Primary)	EdgeConnect virtual appliance deployed in AWS VPC.Direct Connect or broadband overlay to Azure, GCP or On-premise environments. Integrates with AWS Transit Gateway to support complex VPC configurations.
Microsoft Azure	EdgeConnect deployed in Azure VNet. Integrated with Azure Virtual WAN or standalone hub model. Policy-consistent with AWS environment.
Google Cloud Platform	EdgeConnect deployed in GCP VPC. Supports Cloud Interconnect augmentation or pure internet overlay. Full mesh or hub-and-spoke topology options.
On-Premise Environments	EdgeConnect deployed in customer environment, Supports virtual or physical appliances. Full mesh or hub-and-spoke topology options. High-availability (HA) options.
Security Integration	Integration with SD-WAN and SSE environments. Local breakout via SD-WAN to trusted applications, direct egress to SSE (e.g. Zscaler) for traffic inspection. Options for on-board SSE with Aruba EdgeConnect. Ingress using ZTNA.
Management	Full connectivity management including routing, traffic optimisation and real-time congestion management using SD-WAN features through a single management application (better than single pane-of-glass with multiple windows)

Business Value

Hararei's multi-cloud networking solution delivers measurable outcomes across cost, performance, and risk dimensions — the three things every technology leader is ultimately accountable for.

Cost Reduction	Replace expensive dedicated cloud interconnects and MPLS links with broadband overlays. Aruba EdgeConnect customers have reported WAN cost reductions exceeding 90% in some cases.
Performance	Intelligent path selection ensures applications always use the optimal route. Consistent, low-latency connectivity between cloud environments regardless of traffic conditions.
Security Posture	Private traffic is encrypted between sites with end-to-end encryption, preventing snooping even by telecom intermediaries. Private traffic is never exposed to the Internet. Ingress/Egress traffic can be integrated with any SSE solution.
Operational Simplicity	Centralised management via Aruba Orchestrator eliminates per-cloud, per-region configuration complexity. Policy changes propagate globally in minutes. Complex policy changes due to changing business requirements can be implemented immediately instead of needing to reconfigure low-level routers individually.
Agility	Spin up new cloud regions or migrate workloads between clouds without re-architecting the network. The SD-WAN fabric can adapt automatically.
Risk Reduction	Consistent security policy across all cloud environments reduces the attack surface and supports compliance with frameworks such as ISO 27001, SOC 2, and GDPR. Detailed fabric-wide reporting provides comprehensive visibility for administrative or regulatory reporting
