How To Do Highly Available OVD-EUS

Guest Author

Got a question from sales on our mailing list that I think is good to have generally available:

My customer is considering using OVD for EUS (against AD) but worries about having one more point of failure (OVD).
Mark Comment - This is covered in our product documentation as well.

Question - What are the failover solutions available?
Answer - It's easy to make OVD highly available. All that is required that you have 2 (or more) OVD instances installed. Then you can synchronize the configuration. I typically prefer to get 1 server configured and then do the synchronize.

  Question - What  are the best practices?
Answer - After you have multiple OVD instances configured - then you can either put OVD behind an existing hardware load-balancer (most common) or if OVD implementation is restricted to just OVD-EUS, can list the specific OVD servers hostname and ports in the database's ldap.ora file. The reason why I put this caveat is that not all applications lets you list multiple connections for fail-over.

Question - Do we have customers working with highly available OVD solution?
Answer - As far as I know, everyone has OVD deployed in a highly available configuration
