[Kea-users] High Availability

[Munroe Sollog]

We currently use kea in an HA (slightly unsupported setup) and I believe
1.4 will include the rest of the missing pieces for HA (due in a few
weeks).  We have 3 servers in a galera mysql cluster and two dhcp server.
We are double VRRP'ing between them so both IPs always stay up.  Using 1.3,
while some metrics have been screwed up, the core functionality has been
rock solid for ~6 months.
