Using multiple availability zones for a workload cluster in TKG 1.4 on vSphere

3 Comments / ClusterAPI, Install, TKG, vSphere / By

This wouldn’t provide the best experience when you’re planning for DR scenarios and want to ensure some redundancy. There is now the ability to spread nodes across multiple clusters within a single …
