Direct Connect SiteLink
SiteLink is a feature of AWS Direct Connect that makes it possible to send data from one Direct Connect location to another, bypassing AWS Regions. Customers can create global, reliable, and pay-as-you-go connections between the offices and data centers in your global network by sending data over the fastest path between AWS Direct Connect locations.
The first step is to connect the on-premises networks to AWS at any of more than 100 Direct Connect locations worldwide. Next, create Virtual Interfaces (VIFs) on those connections and enable SiteLink. Once all VIFs are attached to the same Direct Connect gateway (DXGW), which is a global and highly available AWS resource, traffic can be sent between them. The data sent, follows the shortest path between AWS Direct Connect locations to its destination, using the fast, secure, and reliable AWS global network.
