Microsoft and AWS Launch High-Speed Multicloud Bridge

Dismantling the Multicloud Barrier

For years, connecting Azure and AWS environments required complex orchestration of physical links, routing, and provisioning. According to The Register, this manual process meant that what should be a straightforward networking decision could take weeks or months to fully implement.

The hyperscalers have now launched a joint solution to abstract that underlying networking complexity. The new service combines Azure Multicloud Interconnect with AWS Interconnect. This allows businesses to establish private, high-speed links directly between infrastructure running on both cloud platforms without third-party workarounds.

This shift comes despite previous claims from both providers to UK regulators that multicloud barriers barely existed. AWS had argued customers could easily switch providers, while Microsoft insisted there was little customer interest in multicloud architectures outside of highly specialised, inconvenient situations.

For South African IT teams, this is a major operational shift. Instead of managing bespoke routing through local data centres, engineers can provision cross-cloud links natively. This reduces the administrative burden and significantly cuts down the lead time for deploying robust hybrid architectures.

High-Speed Performance and Open Standards

Performance is a critical factor for enterprise adoption, especially when syncing data across regions. The new multicloud bridge supports speeds of up to 100 Gbps from day one, with scope for future growth. This high-bandwidth capacity is essential for data-heavy, mission-critical workloads.

The underlying architecture relies on open API specifications. These are the exact same standards developed for the network interoperability tie-up between AWS and Google Cloud late last year. By standardising the connection, Microsoft and AWS are creating a highly predictable deployment route.

Security and uptime guarantees are also built directly into the platform. AWS confirms the service includes MACsec security out of the box. The companies are also targeting four-nines, or 99.99%, availability, allowing businesses to scale their infrastructure at the click of a button.

Local businesses running sensitive financial or healthcare data will appreciate this native MACsec encryption. It ensures traffic moving between Azure and AWS remains secure without requiring third-party virtual appliances, which often add latency and inflate monthly rand operating costs for enterprise compute.

Expanding the Hyperscaler Ecosystem

This partnership is part of a broader industry shift toward genuine interoperability. AWS Interconnect now officially covers all three major rival platforms. Alongside Azure, the service provides dedicated multicloud connectivity into both Google Cloud and Oracle Cloud Infrastructure environments.

Microsoft has also indicated it sees opportunities to extend this open API model further. The company believes the same specifications can enable broader interoperability across other hyperscale cloud providers, moving the industry away from isolated, single-cloud relationships toward a unified network fabric.

This ecosystem expansion offers immense flexibility for South African procurement teams. Businesses are no longer forced to consolidate all their compute spend with a single vendor just to maintain network performance. You can now mix and match services based on specific technical requirements.

For instance, a local enterprise could run legacy databases on AWS while leveraging advanced AI inferencing tools on Azure. This direct bridge ensures that data flows between the two environments without the severe latency penalties traditionally associated with traversing the public internet.

Managing Preview Risks and Timelines

While the technology is promising, the Azure Multicloud Interconnect service is currently only in its preview phase. Microsoft explicitly notes that feature availability, performance targets, and timelines may evolve as the service moves toward general availability. Early adopters must plan accordingly.

Because the service is not yet generally available, we recommend holding off on migrating critical production workloads. Use this time to evaluate your current cross-cloud data transfer costs in rand and map out which applications would benefit most from a direct link.

Interested organisations must contact their Microsoft or AWS account teams directly to join the Azure preview. This is an excellent opportunity for enterprise architects to test the service's scalability and verify if the promised availability holds up under local network conditions.

Testing during the preview phase also allows local teams to assess load-shedding resilience. While the cloud data centres themselves have backup power, ensuring that high-speed data synchronisation completes rapidly between sites is crucial for maintaining data integrity during regional grid instability.

Strategic Impact on Enterprise Compute

Ultimately, this development simplifies enterprise compute strategies. AWS openly admits that the old ways of connecting workloads spanning AWS and Azure were clunky. By removing that manual integration, businesses can focus their budgets on actual compute power rather than complex network plumbing.

The shift to a simplified, software-defined experience abstracts the underlying complexity of multicloud networking. This means South African businesses will spend less time on lifecycle management and physical provisioning, freeing up engineering resources for higher-value AI and infrastructure projects.

When general availability is reached, this bridge will fundamentally change how local enterprises architect their systems. By lowering the technical barriers to entry, companies can confidently adopt a multicloud strategy, switching between cloud providers when they want to without sacrificing performance.
