Simplifying Multi-Cloud and Last-Mile Connectivity with AWS Interconnect

Managing secure, reliable connections between major cloud providers and local data centers has historically been a significant undertaking for networking and security teams. Dealing with VPN tunnels, third-party network fabrics, and complex routing requirements consumes time that teams could better spend on core business logic.

AWS has recently launched a new service aiming to solve this problem: AWS Interconnect.

This newly-available managed private connectivity service significantly reduces the friction involved in establishing cross-cloud and hybrid environments. It simplifies establishing high-speed, private network connections to and from AWS, and brings two major capabilities:

AWS Interconnect – Multicloud

The multicloud capability gives you a managed Layer 3 connection directly between your Amazon Virtual Private Cloud (VPC) and VPCs on other cloud providers—starting with Google Cloud, with Microsoft Azure and Oracle Cloud Infrastructure (OCI) planned for a future release.

For cybersecurity and zero-trust engineering, keeping traffic off the public internet is ideal. With AWS Interconnect, traffic flows entirely via the AWS global backbone and the partner cloud’s private network infrastructure.

Key security and performance benefits include:

• Built-in Encryption: Physical links between AWS routers and the partner cloud provider use built-in IEEE 802.1AE MACsec encryption by default.
• Predictable Performance: Since traffic avoids the internet, enterprises benefit from consistent throughput and stable latency.
• Resiliency: Each connection is designed to span multiple logical links distributed across at least two physical interconnect facilities.

AWS Interconnect – Last Mile

The last-mile capability brings the same turnkey approach to your on-premises environments, branch offices, and remote locations. Instead of navigating complicated physical setups, you can select an internet provider directly via the AWS Console, authenticate, and choose your bandwidth from 1 Gbps to 100 Gbps. The service automatically provisions redundant connections, configures BGP routing, and enables MACsec encryption seamlessly.

Why It Matters

As enterprise multi-cloud architectures grow—often out of necessity for data residency constraints, specific organizational needs, or specialized services—the need for simple, secure cloud interconnectivity is paramount. AWS Interconnect abstracts away the heavy lifting of multicloud networking, replacing weeks of configuration and setup with a few clicks.
