Azure Multicloud Interconnect for AWS: What IT Teams Need to Know

Introduction

Multicloud is now a standard architecture for many enterprises, especially as AI, analytics, and modern app workloads spread across Azure and AWS. The challenge has been networking: private cloud-to-cloud connectivity often requires complex provisioning, routing, and support coordination. Azure Multicloud Interconnect for AWS aims to remove much of that friction.

What’s new

Microsoft and AWS have announced a joint multicloud networking solution built around Azure Multicloud Interconnect and AWS Interconnect – multicloud.

Key highlights include:

• Private connectivity between Azure and AWS through a more streamlined, cloud-native experience
• Open API-based interoperability, designed to reduce manual coordination across providers
• Enterprise-grade resiliency and security, including support for MACsec security
• High availability, with AWS citing four-nines availability
• Scalable bandwidth up to 100 Gbps at general availability
• Integration with Azure Private Link to help create an end-to-end private path between clouds

Why this matters

For many organizations, connecting workloads across Azure and AWS has been slow and operationally heavy. Traditional approaches often involve stitching together multiple services, configuring routing manually, and managing separate lifecycle processes.

This new model matters because it can:

• Speed up deployment of multicloud architectures
• Improve predictability for latency-sensitive and high-bandwidth workloads
• Simplify operations for teams supporting cross-cloud applications and data flows
• Better support AI training and inference scenarios where data and services span multiple environments

Impact on IT administrators

Azure and network administrators should see this as a practical step toward simpler multicloud operations. Instead of focusing on the underlying infrastructure plumbing, teams can spend more time on application delivery, data movement, and governance.

This will be especially relevant for organizations that:

• Run production workloads across both Azure and AWS
• Need private rather than public internet connectivity
• Support data-intensive AI or analytics platforms
• Want a more standardized approach to multicloud networking

The broader message is also important: Microsoft is signaling support for a more open interoperability model that could eventually extend beyond Azure and AWS to other providers and carriers.

Next steps

If your organization already operates in both Azure and AWS, now is a good time to:

• Review current cross-cloud connectivity designs
• Identify workloads that would benefit from private, high-bandwidth links
• Evaluate Azure Private Link dependencies and architecture requirements
• Read Microsoft’s technical guidance and implementation documentation
• Track availability and rollout details for production planning

Azure Multicloud Interconnect for AWS could significantly reduce the time and effort required to build secure, resilient multicloud connectivity—particularly for AI-driven and mission-critical workloads.
