AWS Interconnect: The Managed Layer Multicloud Has Been Missing
Cloud Platform EngineeringBuilding a private connection between AWS and Google Cloud used to mean stitching together BGP configurations, cross-connect cabling, and carrier agreements. AWS just made it a line-item service.
Context
AWS Interconnect reached general availability on April 14, 2026, introducing two variants: Interconnect Multicloud, which establishes managed private Layer 3 connections between AWS VPCs and other cloud providers, and Interconnect Last-Mile, which extends the same managed approach to on-premises and remote locations via third-party network providers. The initial multicloud launch supports Google Cloud across five US and European region pairs; Microsoft Azure and Oracle Cloud Infrastructure are committed for later in 2026. A jointly engineered open specification covers the underlying protocol, allowing additional cloud providers to build compatible implementations.
The Detail
Interconnect Multicloud routes traffic entirely over the AWS global backbone and the partner cloud’s private network — bypassing the public internet completely. Every physical link between AWS routers and partner cloud provider routers uses IEEE 802.1AE MACsec encryption at the interconnection facility level. BGP routing is configured automatically; engineering teams do not manage peering session setup or maintenance manually. CloudWatch Network Synthetic Monitor integration is included for latency and packet loss tracking. The five live region pairs span US East (N. Virginia), US West (N. California), US West (Oregon), Europe (London), and Europe (Frankfurt), each mapped to the corresponding Google Cloud region.
Interconnect Last-Mile extends this pattern to hybrid scenarios, launching in US East (N. Virginia) with Lumen as the first network provider and AT&T and Megaport in the partnership pipeline. It carries a 99.99% availability SLA — a threshold most enterprises cannot reliably meet operating their own last-mile infrastructure. Pricing follows flat hourly rates per bandwidth tier, varying by region pair.
The distinction from AWS Direct Connect is operationally specific: Direct Connect handles private connections between on-premises environments and AWS but was not designed for cross-cloud provider connectivity or managed third-party network integrations. Interconnect addresses the scenarios Direct Connect was never built to cover. For teams currently managing cross-cloud connectivity through transit gateways, site-to-site VPN tunnels, or colocation peering arrangements, this is a serviceability upgrade — not an architectural change.
The Pattern
AWS has been running a consistent infrastructure simplification playbook in 2026: EKS Auto Mode removed cluster node management overhead; S3 Files added a POSIX filesystem API layer over object storage. Interconnect removes the most operationally intensive components of cross-cloud networking — physical infrastructure coordination, BGP management, and per-link encryption configuration — and converts them into a managed service with an SLA. The through-line across all three is the same: abstract the plumbing, contract the blast radius, reduce the specialized expertise required to operate at production scale.
The So What
Multicloud network architecture has historically required dedicated network engineering talent to design, validate, and maintain. Interconnect does not eliminate that expertise requirement — architecture decisions still matter, and teams need to understand what their traffic patterns and latency tolerances actually require. But it removes the most operationally intensive components from the task list. For organizations currently evaluating cross-cloud connectivity for multi-vendor AI workloads, data residency compliance, or team-specific platform standardization, Interconnect is worth evaluating before Azure and OCI support arrives. The open specification also signals that AWS intends this to become the standard mechanism for private cross-cloud connectivity rather than a bilateral arrangement with any single partner.
