Bosh beginner

hemant patre

I have read online docs for bosh and followed steps to install bosh and director. Once succeed with these steps I deployed zookeeper as per online example. It seems it created 5 instances. But where did it create these 5 instances (VM) on my machine or inside director VM?

I want to develop tool which can deploy few softwares on multiple machines. For ex. I have 4 boxes with me A, B, C, D. I want to install bosh director on A and install softwares on remaining 3 boxes (B, C, D). How to set bosh? It seems bosh director deals with only one machine, is this true?
