AWS Direct Connect provides a private, high-bandwidth network link between your on-premises environment (data center, office, or colocation facility) and AWS. Unlike Internet-based VPNs over IPSec tunnels, Direct Connect offers dedicated 1 Gbps, 10 Gbps, or 100 Gbps connectivity, delivering consistent low latency, higher throughput, and enhanced security.

​
Key Components

​
Establishing a Connection

  1. Order a Port
    Request a 1 Gbps, 10 Gbps, or 100 Gbps port in your chosen Direct Connect location.
  2. Cross-Connect Provisioning
    Work with the facility operator to install a cross-connect cable between your customer router and the AWS Direct Connect router.
  3. BGP Session Setup
    Configure Border Gateway Protocol (BGP) peering on both ends to exchange routes dynamically over the AWS global network.
Ensure your on-premises edge device supports the desired port speed and BGP configuration.

Virtual Interfaces (VIFs)

After your physical link is active, segment traffic by creating virtual interfaces: Each VIF leverages BGP to advertise and learn routes, ensuring efficient traffic flow.
