Currently I have one requirement that :

Let's say I have 2 applications A & B where A talks to B. I want to deploy them on Azure Kubernetes Service clusters with 5 nodes each having a Pod with container containing one instance of the application.

So 2 Clusters, say ClusterA and ClusterB

ClusterA has nodes N1, N2, N3, N4, N5

ClusterB has nodes N6, N7, n8, N9 and N10.

I have 2 sets of users U1 and U2 . I want to logically partition my clusters such that request from

U1 - https -> clusterA( N1, N2, N3) -- HTTP(Rest) -> Cluster B(N6, N7,N8)
U2 - https -> clusterA( N4, N5) -- HTTP(Rest) -> Cluster B(N9, N10)

What is the right way to do it if we want to have maximum control on the 2 separate partitions without impacting each other ?
