AWS Interconnect Expands to Azure: Seamless Multicloud Connectivity Now in Preview

The core vision behind AWS Interconnect is to provide a purpose-built product that redefines how cloud environments connect and communicate. This initiative was initially previewed at re:Invent 2025, where AWS published an open specification for network interoperability, inviting the broader ecosystem to adopt its framework. The inclusion of Microsoft Azure as the latest cloud service provider to adopt this specification marks a major milestone in achieving true multicloud agility.

For developers, this translates into a significant reduction in the effort and expertise required to establish high-performance, secure, and resilient connections between their AWS and Azure resources. Instead of grappling with disparate networking models, VPNs, or direct connect solutions that terminate at separate locations, they can now manage their multicloud connectivity through a single, unified, and managed experience provided by AWS. This consistency simplifies network architecture, reduces potential points of failure, and frees up valuable developer time to focus on application logic and innovation rather than infrastructure plumbing. The underlying open specification promotes a standardized approach, which is crucial for fostering a more interoperable cloud landscape.

The benefits extend beyond just technical simplification. Businesses often adopt multicloud strategies for various reasons, including regulatory compliance, disaster recovery, vendor lock-in avoidance, and the ability to utilize specialized services unique to each provider. AWS Interconnect directly supports these strategic objectives by making the technical execution of multicloud architectures more feasible and less burdensome. It addresses the critical need for efficient data movement and application communication between these environments, which is essential for modern distributed applications and microservices architectures.

AWS Interconnect – multicloud with Microsoft Azure allows customers to provision resilient, scalable private connections to Azure directly from their AWS environment. This managed service eliminates the need for customers to build and maintain complex global networks themselves. The preview is currently available in specific AWS Regions: US East (N. Virginia), US West (N. California), Asia Pacific (Sydney), and Europe (Frankfurt).

Developers can create an Interconnect using the AWS Management Console, Command Line Interface (CLI), or API, offering flexibility based on their preferred automation and management tools. This integration means that the familiar AWS ecosystem can now be used to configure and monitor connectivity to Azure, providing a consistent operational experience. The underlying technology likely leverages direct peering arrangements between AWS and Azure's global networks, abstracting away the physical and logical complexities from the end-user.

Key aspects of this integration include:

• Simplified Provisioning: Instead of negotiating separate direct connect or express route agreements and configuring complex routing, developers can provision connections with a few clicks or API calls within AWS.
• Private Connectivity: The connections are private, bypassing the public internet, which enhances security, reduces latency, and provides more predictable network performance. This is crucial for sensitive data transfers and latency-sensitive applications.
• Scalability and Resilience: The managed service is designed to offer scalable bandwidth and built-in resilience, ensuring that multicloud workloads can handle varying traffic demands and maintain high availability.
• Consistent Experience: AWS Interconnect – multicloud already supports Oracle Cloud Infrastructure (OCI) and Google Cloud (both Generally Available), and now extends this consistent, simple experience to Microsoft Azure (Preview). This broadens the reach of a unified connectivity model across major cloud platforms.

This capability is particularly beneficial for scenarios such as:

• Running analytics workloads in AWS that need to access data stored in Azure Blob Storage or Azure Data Lake.
• Deploying microservices in one cloud that rely on APIs or databases hosted in another.
• Implementing hybrid cloud architectures where on-premises data centers connect to both AWS and Azure for redundancy or specialized services.
• Facilitating seamless data migration projects between the two cloud providers.

The introduction of AWS Interconnect's public preview with Microsoft Azure significantly impacts developer workflows by abstracting away a substantial portion of multicloud networking complexity. Developers can now focus more on application logic, data processing, and user experience, rather than spending valuable time on intricate network configurations, troubleshooting connectivity issues, or managing security policies across disparate cloud environments. This shift empowers development teams to be more agile and efficient in building and deploying multicloud applications.

For instance, an application developer might leverage AWS's machine learning services while storing sensitive customer data in Azure to meet specific compliance requirements. With simplified interconnectivity, the data transfer and API calls between these services become much more straightforward and reliable. This fosters greater innovation by enabling developers to easily combine the best-of-breed services from each cloud provider to create more robust and feature-rich applications.

Furthermore, this development lowers the barrier to entry for organizations considering or already implementing multicloud strategies. The reduced operational overhead and simplified management make multicloud less daunting and more accessible. It also provides a stronger foundation for implementing advanced architectural patterns like active-active multicloud deployments or sophisticated disaster recovery strategies that span across AWS and Azure. The ability to use a single console or API for managing these connections streamlines automation efforts and integrates seamlessly into existing CI/CD pipelines, further enhancing developer productivity.
