In my last blog post, I have covered one option to connect On-Premise data center to Aviatrix Transit via Direct Connect, it’s easy to implement however with following draw backs:

• Each IPSec tunnel between Aviatrix Transit and AWS Virtual Private Gateway (VGW) is limited to 1.25Gbps of throughput, and we can only have 4 tunnels which limits the aggregated throughput to 5Gbps. For customer want to have higher throughput, this won’t be viable.
• Private Virtual Interface support up to 100 BGP routes, BGP session will go DOWN when more routes been advertised
• Between On-Premise to VGW, traffic maybe protected by MACSec, but still expose to man in the middle attack. Reference article: Securing your network connection to the cloud: MACSec vs. IPSec

How do we overcome these constrains? Let me take you through the second option connecting to Aviatrix Transit via Direct connect.
