Tech Notes

On your AWS console, review EC2 instances page and check the Gateway instances created. The instances have a Name tag that begins with valtix.

  • Gateway Load Balancer (GWLB), GWLB Endpoint Service and GWLB Endpoints are created
  • The route table (named as <prefix>-nat-ingress) in Service VPC has a default route to the GWLB endpoint

AWS Gateway Load Balancer (GWLB) does not support add/remove of AZs after initial deployment of a GWLB. You will need to redeploy the Service VPC if you need to change AZs.
