I'm looking for alternatives to using GCP load balancer to direct traffic to apps.
When I used a managed load balancing solution, for example, GCP HTTPS load balancer, if the number of VMs increases in my cluster, this dynamically keeps track of the changes in the cluster, and therefore seamlessly knows the new IP addresses of the new VMs to send traffic to.
With nginx reverse proxy (installed on an instance), as far as I'm aware, you configure a forward address in the initial setup telling the proxy which addresses to send traffic to. Does this mean it cannot be used to seamlessly redirect traffic to a cluster which autoscales and therefore regularly includes new machines with brand new IP addresses that are not configured in the forwarding configuration? Or does it have some mechanism to deal with this?
