VMware Cloud on AWS provides multiple ways to establish a network connectivity from on-premises including different types of VPNs and AWS Direct Connect (DX). AWS Direct Connect (DX) is a service provided by AWS that allows you to create a high-speed, low latency connection between your on-premises data center and AWS services including VMware Cloud on AWS.
When you are planning to use your SDDC in VMware Cloud on AWS to host enterprise applications workload and it’s expected to have extensive traffic to/from these applications and/or the traffic is latency-sensitive, we recommend using AWS Direct Connect (DX).
NOTE: Traffic over Direct Connect is not encrypted. If you want to encrypt that traffic, configure your L3 VPN to use Direct Connect.
