Articles on setting up highly available DNS/DHCP servers using MySQL Cluster

I found this old article that shows how to setup
highly available DNS/DHCP servers using MySQL Cluster.

It uses 4 machines with 4 replicas, it describes how to do it with MySQL Cluster 7.3,
obviously today it would make more sense to use 7.5 or 7.6. In this case an extension
would be add ndb_read_backup=on to my.cnf to ensure that all MySQL servers in the
clusters reads the local copy rather than going over the network to read from another
replica.

Another tool that I found and discussed in my book on MySQL Cluster that uses
NDB for DNS and DHCP is Kea, here is an article describing how to setup Kea using NDB.
