Ah,

If I understand the suggestion there correctly, it is to have two
clusters, with a total of 4 nodes:

Cluster 1:

App 1 + App 3

Cluster 2:

App 2 + App 4


The cluster configuration on both clusters should be the same:

1. Your services
2. A ticket that allows your services to run when granted

Then use booth to connect the clusters and move the services from
cluster 1 (App 1 and App 3) to cluster 2 (App 2 and App 4).

Cheers,
Kristoffer
