I have a doubt, I know that with ambari there is still no HA issue unless it is through a balancer for LDAP. But my doubt is possible to have some type of HA for example for the DNS and the KDC, that is to say if I have 2 Servers Windows, with the same domain for example Thisysten.local is possible to have a HA for the DNS and for the KDC?
And another scheme if I have 2 windows servers one for production and another for development like
It could be used even for the 2 Instances i.e. You can fill in ambari and have requests for HA for each server. in KDC for each environment.
