AWS and Azure Launch Native Direct Interconnect to Eliminate Multi-Cloud Networking Friction

Microsoft and Amazon Web Services (AWS) have announced the public preview of native cross-cloud interconnectivity, integrating Azure Multicloud Interconnect with AWS Interconnect – multicloud. Built upon an open API specification for network interoperability, the service enables enterprises to provision private, managed Layer 3 network links between AWS VPCs and Azure Virtual Networks directly from their respective cloud consoles or Infrastructure as Code (IaC) pipelines. Initially available across key regions in the US, Europe, and Asia Pacific, the offering eliminates the need for customer-managed physical cross-connects, third-party colocation facilities, and manual border gateway protocol (BGP) orchestration. For infrastructure and network engineering teams, private multi-cloud connectivity has traditionally been one of the most operationally burdensome aspects of distributed architecture. Stitching together Azure ExpressRoute and AWS Direct Connect historically required contract negotiations with colocation providers, physical patching, custom router provisioning, and bespoke encryption management. By turning cross-cloud peering into a first-class, provider-managed resource with built-in MACsec security and automated high resiliency, platform teams can now establish secure, high-bandwidth links in minutes rather than months. This partnership marks a critical maturation point in the multi-cloud ecosystem. While container orchestration via Kubernetes and vendor-neutral data platforms solved application portability at the compute layer, networking remained the primary bottleneck locking enterprises into single-cloud silos. Furthermore, the explosion of distributed AI workflows—where training datasets, foundation models, and specialized inference accelerators frequently reside across different providers—has accelerated customer demand for low-latency, deterministic cross-cloud data transfer. Following previous interconnect rollouts with Google Cloud and Oracle Cloud Infrastructure, Azure’s integration completes native connectivity across the dominant hyperscalers. Practitioners should evaluate this managed interconnect for latency-sensitive cross-cloud architectures, such as split-tier application deployments, cross-cloud disaster recovery, and unified data mesh architectures. However, platform architects must account for operational boundaries: while the physical layer and baseline routing are automated, teams remain responsible for end-to-end IP address management (avoiding overlapping CIDR blocks), transit routing policies via AWS Transit Gateway or Azure Virtual WAN, and egress bandwidth costs. While currently in public preview and subject to preview terms, engineering teams should begin prototyping cross-cloud routing designs to replace brittle DIY interconnects as these capabilities advance toward general availability.
