Why would I want to use DNSaaS (Designate) over a traditional bind/nsupdate setup?
I'm looking into setting up a DNS zone for use with OpenStack.
I'm not sure what benefits I would get from working with DNSaaS (Designate/pdns) over using bind and nsupdate.
At the expense of saying "we've always done it that way", I think it makes sense for me to work with the older DNS stack, because that's what me and my peers are more familiar with. Please convince me to take the red pill.
In addition to jmcbride's answer, I found this video describing Designate/Moniker, and specifically asking "why would I use DNSaaS?" - http://www.openstack.org/summit/portland-2013/session-videos/presentation/dns-in-the-cloud-the-moniker-openstack-inspired-dns-project%3C/p%3E (http://www.openstack.org/summit/portland-2013/session-videos/presentation/dns-in-the-cloud-the-moniker-openstack-inspired-dns-project)
