Amazon OpenSearch Service now supports VPC egress for private connectivity to resources in your VPC

Amazon OpenSearch Service now supports the VPC egress option, which allows your virtual private cloud (VPC) domain to establish private network connections to resources in your VPC, such as ML models, AWS services, and custom applications, without exposing traffic to the public internet. When you enable the VPC egress option, OpenSearch Service adds network interfaces to the subnets you selected for the domain and routes outbound traffic into your VPC.
