The two most popular approaches to run Kubernetes workloads on different sites are to have:
Note: Certain Kubernetes distributions, such as OpenShift, impose a low latency between sites to allow stretched clusters. For information about latency with OpenShift, see this Red Hat blog. The same scenario applies with SRDF, where latency is a constraint that is more or less relaxed depending on the replication type. For information about SRDF latency, see SRDF Introduction.
