I need recommendation for loadbalncers for the two use cases mentioned below. I have two sets of kubernetes(RKE2) clusters located in two different geographical locations.
One of the clusters act as an Active cluster and the other as a Standby cluster. Now I need a recommendation for loadbalancer before these two clusters to route the traffic always to the Active cluster.
If the control nodes of the Active cluster fail then the Standby cluster should be elected as Active cluster and the traffic should route to the newly elected Active cluster.
Both the clusters act as Active clusters. Here I need another recommendation for a loadbalancer to route the traffic to the cluster that responds quicker than the other.
