Dedicated machines are a good idea. The main thing is to make sure that ZK
always has IOPS available for transaction log writes. That's easy to ensure
when each ZK instance has its own hardware. The standard practice, as far as I
know, is to have 3 physical boxes spread among racks/datacenters/c
Yes, always use three or a higher odd number of machines. It is best to have
them on dedicated machines and unless the cluster is very large three small VPS
machines with 512 MB RAM suffice.
