AWS and Microsoft Azure Launch Private Multicloud Connectivity — What It Means for Channel Partners
On August 31, 2026, AWS and Microsoft Azure jointly announced that AWS Interconnect – multicloud now supports Microsoft Azure in Public Preview. The service enables private, MACsec-encrypted, high-performance connectivity between AWS and Azure workloads — connectivity that previously required weeks of provisioning through third-party networking vendors can now be established in minutes via a three-step console workflow. For channel partners who advise enterprise customers on multicloud strategy, manage cross-cloud infrastructure, or build software that spans both environments, the announcement changes the calculus on where multicloud is a viable default and where it remains a niche play.
What Was Announced
AWS Interconnect – multicloud is an open-specification service that allows customers to establish private connectivity between AWS and other cloud providers without routing traffic over the public internet. Azure becomes the third major provider to join, following Google Cloud (which reached general availability on April 14, 2026) and Oracle Cloud Infrastructure (GA July 29, 2026). According to Microsoft's announcement, the integration is branded Azure Multicloud Interconnect for AWS on the Azure side, and it targets the same enterprise workload segments AWS has been addressing since the service's inception.
Technically, the preview supports up to 100 Gbps of bandwidth, quad-redundant architecture, and a four-nines availability target. Preview regions are US East (N. Virginia), US West (N. California), Asia Pacific (Sydney), and Europe (Frankfurt) — a footprint that covers the primary enterprise hubs where AWS-Azure dual-cloud deployments are most common. The open API specification is published on GitHub, signaling an intent to position this as a durable vendor-neutral standard rather than a proprietary integration that either side controls.
How the Connection Works
From a provisioning standpoint, the workflow collapses what was previously a multi-week engagement involving Direct Connect, ExpressRoute, and a colocation or exchange provider into a guided three-step flow within each cloud console. Partners who have managed enterprise customers through the legacy setup process understand the friction involved: coordinating Direct Connect and ExpressRoute orders, arranging physical cross-connects at a neutral exchange, negotiating BGP peering sessions, and validating end-to-end latency and throughput — often across three or four vendors simultaneously. The new service replaces that complexity with a provisioning model that mirrors how customers connect VPCs and VNets within a single cloud.
For MSPs and network integrators, this matters because the activation curve for multicloud network services shortens substantially. Managed connectivity that once required dedicated pre-sales engineering effort and weeks of onboarding can now be positioned as a standard service line rather than a bespoke engagement. The margin structure of MSP cloud practices is already under pressure from commoditization of pure resale; adding managed multicloud connectivity as a differentiated service tier — one with real setup complexity that customers value — is a structural opportunity the preview creates.
Channel and MSP Implications
The most immediate channel implication is for MSPs and system integrators who already manage customers running workloads on both AWS and Azure. That segment is larger than it appears: most enterprise customers who went through digital transformation programs between 2018 and 2024 ended up with material AWS and Azure footprints through different business units, acquisitions, or SaaS vendor dependencies. These customers have been managing connectivity between those environments through workarounds — VPN over the internet, private colocation cross-connects, or simply accepting that workloads on different clouds do not communicate with each other directly.
AWS Interconnect – multicloud with Azure gives partners a standardized solution to offer to that installed base. Building a durable multi-cloud hyperscaler partner strategy has historically required significant investment in network practice capabilities that many mid-market MSPs could not justify. The new service lowers that bar because the provisioning complexity is absorbed by the platform rather than the partner's professional services team.
For partners who are already AWS Advanced or Premier tier, the service also has co-sell implications. AWS has signaled through its broader Partner Central investments that it wants to increase co-sell engagement on customer migrations and infrastructure modernization. Multicloud connectivity deals that involve new AWS workloads — customers consolidating Azure workloads onto AWS over time while maintaining hybrid connectivity — are likely to qualify for co-sell support. Partners should verify eligibility with their AWS Partner Development Manager before positioning the preview with customers, as the co-sell workflow for preview-stage services can differ from GA offerings.
What ISVs Must Do to Benefit
The announcement has a less obvious but equally significant implication for ISVs. Enterprise SaaS products that have historically been deployed exclusively on one hyperscaler — often because the customer's IT policy required it — face a different dynamic when the customer's data and compute can move seamlessly between AWS and Azure. ISVs who want to position their products as multicloud-native need their applications to behave correctly in a cross-cloud deployment: service discovery, identity federation, data consistency across regions, and observability pipelines all require deliberate engineering when the underlying network spans two hyperscalers.
For ISVs who have not invested in multicloud-native architecture, this becomes a competitive pressure point as the preview matures toward GA. Customers who can now route data between AWS and Azure with enterprise-grade latency and security will increasingly ask whether their ISV's product can operate as a first-class citizen in that topology. Retrofitting a single-cloud application for genuine multicloud readiness — not just "runs on both" but "designed to run across both concurrently" — typically involves custom software development work that cannot be delivered through configuration alone: refactoring service boundaries, implementing cloud-agnostic identity layers, and validating data residency controls across two distinct compliance regimes. ISVs who begin that work during the preview window will be better positioned when the service reaches GA and customer demand accelerates.
ISVs building marketplace-listed products should also consider how multicloud connectivity affects their listing strategy. A product that can be deployed and managed across AWS and Azure through a single operational plane becomes a more compelling Marketplace offer than one that requires a separate deployment per cloud. AWS and Azure have both invested in their marketplace listing infrastructure over the past two years precisely to attract ISVs who can serve customers at this complexity level.
The Broader Multicloud Context
The Azure addition to AWS Interconnect – multicloud completes the major hyperscaler triangle: AWS, Azure, and Google Cloud now have two-way private connectivity options available through the same open-specification service, with Oracle Cloud as a fourth participant. From a channel perspective, this is a structural shift rather than a product feature. The prior constraint — that each cloud was, in effect, an island connected to others only through the public internet or expensive bespoke setups — has been a persistent argument against genuine multicloud strategy at the enterprise level. That argument weakens as the connectivity layer matures.
Partners who have been advising customers to simplify to a primary cloud with secondary-cloud exceptions should revisit that guidance as the preview matures. The operational overhead that justified consolidation was largely a function of connectivity cost and complexity; as those reduce, the calculus shifts toward best-of-breed cloud service selection across providers. That shift creates new advisory opportunities for channel partners with the technical depth to navigate cross-cloud architecture — and new competitive threats for partners who have built their practices around single-cloud depth.
The Public Preview status means the service is not yet production-ready for all workload types. Partners should set appropriate expectations with customers about SLA coverage, feature completeness, and pricing transparency during the preview period. AWS and Azure have not published final GA pricing; partners should avoid committing to cost models based on preview-period pricing until GA terms are confirmed.
