If I understand the suggestion there correctly, it is to have two
clusters, with a total of 4 nodes:
App 1 + App 3
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).
