Deploying ECE on AWS EC2 and Multiple AZs

The account I'm using at AWS to deploy ECE to has 4 available AZs. ECE only requires 3 for a Fault Tolerant install. Should I configure it to only use 3 out 4 or use all 4?


You can definitely use all 4 though you don't get much benefit from doing so ... ECE will pick 3 out of the 4 zones to deploy to for each HA cluster

(You should only have 3 or 5 ZK servers though)

Thanks, I'll manually put it to 3 AZs for now.
