Azure Multicloud Interconnect Accelerates Private AWS Connectivity

Microsoft unveiled Azure Multicloud Interconnect, a service that creates a dedicated, low‑latency bridge between Azure and Amazon Web Services. By linking ExpressRoute and AWS Direct Connect through a common backbone, enterprises can move data, AI models, and workloads across the two clouds without traversing the public internet, cutting latency and boosting security at a time when hybrid architectures dominate IT roadmaps.

At its core, the offering stitches together Azure ExpressRoute circuits with AWS Direct Connect links using industry‑standard BGP routing and MEF‑3.0‑compliant Ethernet frames. Traffic flows over Microsoft’s private fiber network, preserving end‑to‑end encryption and offering SLA‑backed throughput up to 100 Gbps per connection. Customers configure a virtual network gateway in Azure, a virtual private gateway in AWS, and a peering session that automatically synchronises routing tables, eliminating the need for complex VPN overlays.

The launch arrives amid a surge in multicloud adoption; Gartner predicts 75% of enterprises will run workloads on two or more clouds by 2025. Competitors such as Google Cloud’s Dedicated Interconnect and Alibaba Cloud’s Express Connect have already targeted similar use cases, but Azure’s deep integration with Microsoft’s AI stack gives it a unique edge. Market analysts estimate the global private interconnect market will exceed $12 billion by 2027, driven by demand for secure, high‑performance data pipelines.

For India’s fast‑growing tech sector, the service unlocks new possibilities. Large conglomerates like Tata Consultancy Services and Reliance Industries, which maintain hybrid footprints on Azure and AWS, can now route financial‑grade data between Mumbai and Singapore data hubs without exposing it to the public internet. Indian fintech startups, AI research labs, and government‑backed digital initiatives stand to benefit from reduced latency in real‑time analytics and compliance‑friendly data residency, aligning with the nation’s push for sovereign cloud capabilities.

Key Highlights

• Launches a private, carrier‑grade link between Azure and AWS
• Supports up to 100 Gbps throughput with MEF‑3.0 standards
• Reduces multicloud latency by up to 40 % versus VPN alternatives
• Enterprises and cloud‑native developers gain seamless AI workload mobility
• Full rollout expected Q1 2025, with expanded regional pairs later

Real-World Impact

Cloud architects can now design truly hybrid pipelines without relying on costly VPN appliances, while DevOps teams gain a single pane of glass for network monitoring. Data scientists handling large model training sets will see faster cross‑cloud transfers, and finance firms can meet stringent latency requirements for algorithmic trading. The service also opens a new revenue stream for managed service providers that specialise in multicloud integration across India and APAC.

Why This Matters

The move signals a broader shift from siloed public‑cloud deployments toward interoperable, private‑network‑first strategies. CTOs must rethink network topologies, favouring direct interconnects over internet‑based links to meet performance and compliance goals. Developers should start refactoring applications to exploit low‑latency pathways for data‑intensive workloads, especially as AI workloads become more distributed across clouds.

Microsoft plans to extend the interconnect framework into Azure Virtual WAN and introduce automated billing dashboards by mid‑2025. Watching how the service scales across emerging markets, especially in India’s tier‑2 cities, will reveal whether private multicloud links become the new baseline for enterprise cloud strategy.
