Unfortunately o= ne of our customers is not very happy of having to run a minimum of three Z= ooKeeper server instances to ensure fail over. The customer has two data ce= nters in different locations where data and applications are replicated and= some big-ip appliance in front of the data centers. If one data center fai= ls everything must still be operable. So he would prefer to only have two = instances one in each data center. I would be grateful for some advise how = to best cope with these contradicting requirements. Cheers, Zsolt Beothy-Elo=
