Hi,
I find very useful the article of the knowledge base ["Denodo Platform Cluster Architecture"](https://community.denodo.com/kb/view/document/Denodo%20Platform%20Cluster%20Architecture?category=Best+practices).
Also, I recommend you to take a look at the documentation about ["Cluster architectures/Server backup"](https://community.denodo.com/docs/html/browse/6.0/vdp/administration/cluster_architectures_server_backup/cluster_architectures_server_backup).
Hope this helps!
