AWS Interconnect is a managed service for private, high-speed connectivity between AWS and other clouds or on-premises networks. Its multicloud capability, now generally available, initially connects AWS with Google Cloud while Microsoft Azure support is planned for later in 2026. The service aims to replace complex VPN, colocation, and third-party networking setups with a turnkey, resilient configuration managed through AWS.

AWS Interconnect Capabilities

  • Interconnect – multicloud connects an AWS VPC privately to VPCs on other cloud providers.
  • Interconnect – last mile simplifies connectivity from branch offices, data centers, and remote sites through existing network providers.
  • Both capabilities provide:
    • Dedicated bandwidth
    • Private connectivity
    • Managed provisioning
    • Reduced infrastructure and configuration overhead
  • Connections can be configured through the AWS Console by selecting the location or provider, AWS Region, and bandwidth.

Multicloud Connectivity

  • The service provides a managed Layer 3 connection between AWS and another cloud provider.
  • Traffic uses the AWS global backbone and the partner’s private network rather than the public internet.
  • This improves:
    • Latency predictability
    • Throughput consistency
    • Isolation from internet congestion
  • Google Cloud is supported at launch; Microsoft Azure is expected later in 2026.

Security, Resilience, and Monitoring

  • Physical links between AWS and partner routers use IEEE 802.1AE MACsec encryption by default.
  • Each cloud provider handles encryption on its own backbone, so customers must verify that the resulting deployment satisfies compliance requirements.
  • Connections use multiple logical links across at least two physical facilities to protect against device or facility failures.
  • Amazon CloudWatch integration includes:
    • A Network Synthetic Monitor for round-trip latency and packet loss
    • Bandwidth utilization metrics for capacity planning

Open Partner Specification

  • AWS has published the underlying Interconnect specification on GitHub under the Apache 2.0 license.
  • Other cloud providers can become partners by implementing the specification and meeting AWS requirements for:
    • Resiliency
    • Support
    • Service-level agreements
    • Operational readiness

Provisioning an AWS–Google Cloud Connection

  • The demonstration connects a single AWS VPC to a Google Cloud VPC using a Direct Connect Gateway.
  • In the AWS Direct Connect console, the user:
    • Selects Google Cloud as the provider
    • Chooses AWS Region eu-central-1
    • Chooses Google Cloud Region europe-west3
    • Specifies bandwidth
    • Selects a Direct Connect Gateway
    • Enters the Google Cloud project ID
  • AWS then generates an activation key for use on the Google Cloud side.

Configuring Google Cloud

  • Because a Google Cloud web console option was unavailable at the time, the example uses the gcloud CLI.
  • The user creates a transport resource with:
    • The AWS activation key
    • The Google Cloud region
    • The target VPC network
    • Advertised AWS routes
  • After the transport reaches the appropriate state, the user creates a VPC peering connection between the Google Cloud VPC and the generated transport network.
  • Custom routes are imported and exported through the peering configuration.

Completing the AWS Configuration

  • Once the Google Cloud transport and peering are configured:
    • The AWS Interconnect status can be checked in the Interconnect console.
    • The Direct Connect Gateway shows the new attachment.
  • The final AWS-side step is associating the gateway with the appropriate Virtual Private Gateway.
  • The Virtual Private Gateway must be in the same AWS Region as the Interconnect.
  • AWS routing still requires a final route entry so workloads can reach the remote Google Cloud network.

AWS Interconnect is best suited to organizations operating hybrid or multicloud environments that want private, resilient connectivity without managing physical links or complex third-party networking. The managed provisioning process can reduce setup time to minutes, but teams should still validate routing, encryption responsibilities, regional constraints, and compliance requirements.
