Simplifying Multicloud: AWS Launches Interconnect Services

For enterprises managing complex, multi-cloud architectures, the challenge of connecting disparate environments has long been a source of significant engineering overhead. AWS has officially addressed this “undifferentiated heavy lifting” with the general availability of AWS Interconnect – multicloud and AWS Interconnect – last mile, two managed services designed to streamline secure, private connectivity.

Bridging the Cloud Divide

As organizations adopt multicloud strategies to meet data residency requirements or leverage specialized services, they often face the burden of managing VPN tunnels and complex third-party network fabrics. AWS Interconnect aims to remove this friction by providing a fully managed, high-speed connection service directly through the AWS Management Console.

The AWS Interconnect – multicloud capability enables private, Layer 3 connectivity between Amazon Virtual Private Clouds (VPCs) and other cloud providers. As of April 2026, Google Cloud is the initial launch partner, with Microsoft Azure and Oracle Cloud Infrastructure (OCI) support scheduled for later in 2026.

Key Technical Features

• Enhanced Security: Connections utilize IEEE 802.1AE MACsec encryption on physical links between AWS and partner routers by default, ensuring data is protected in transit.
• Predictable Performance: By routing traffic over the AWS global backbone and partner private networks, the service avoids the public internet, providing consistent throughput and latency.
• Resiliency: Each connection is architected to span multiple logical links across at least two physical facilities, preventing single-point-of-failure outages.
• Monitoring: Integration with Amazon CloudWatch provides visibility into round-trip latency, packet loss, and bandwidth utilization.

Last-Mile Connectivity

Complementing the multicloud offering, AWS Interconnect – last mile simplifies the connection between private on-premises data centers or branch offices and the AWS cloud. By automating the provisioning of redundant connections and BGP routing, this service allows businesses to establish private paths to AWS without the manual configuration typically required for network infrastructure. The service supports bandwidth tiers ranging from 1 Gbps to 100 Gbps and includes a 99.99% availability SLA up to the Direct Connect port.

Implementation and Strategy

Provisioning these connections is designed to be straightforward. Users initiate the request in the AWS Direct Connect console, select their provider and bandwidth requirements, and receive an activation key to finalize the setup on the partner side. For growing deployments, AWS recommends pairing these services with AWS Transit Gateway for centralized routing or AWS Cloud WAN for global, policy-driven network management.

Critical Configuration Considerations

To ensure a successful deployment, network architects must account for several technical requirements:

• Address Space: VPC IP ranges on both sides of the connection must not overlap.
• MTU Consistency: Maximum Transmission Unit (MTU) settings must be identical across peered VPCs to prevent packet loss or fragmented data.
• Protocol Alignment: If configuring IPv4 or IPv6, the selection must match on both sides of the interconnection.

Key Takeaways

• Managed Turnkey Experience: AWS Interconnect removes the need for manual VPN and third-party fabric management.
• Availability: The multicloud service is currently available in five region pairs, including connections between US East (N. Virginia), US West (Oregon/California), and Europe (London/Frankfurt) and their respective Google Cloud regions.
• Pricing Structure: Costs are based on a flat hourly rate for the requested capacity, with rates varying depending on the specific region pair.

By shifting the burden of network configuration to a managed service, AWS is signaling a broader industry move toward more interoperable cloud environments. As support for additional providers like Azure and OCI rolls out throughout 2026, the complexity of maintaining a multicloud footprint is expected to decrease significantly for enterprise IT teams.
