AWS Direct Connect is a service that establishes a dedicated network connection between an on-premises data center and an AWS region. This can improve network performance, reduce costs, and increase security for applications that require high bandwidth and low latency1.

A layer 2 VPN connection would not improve performance as it still relies on the public internet. VMware HCX is a service that simplifies workload migration and mobility between different clouds, but it does not address network performance issues. Contacting VMware support to request more bandwidth for IPSec VPN connection is unlikely to be effective as IPSec VPN has inherent limitations such as encryption overhead and packet fragmentation
