[chef] Multi-node chef run orchestration

[M G < >]

I have node1 and node2. Each node has chef-client running on it.

Is it possible that after chef-client run on node1 is complete, it can it start/trigger a chef run on node2? 

Does chef have the ability to perform orchestration of runs on the basis of some triggers?

Another thing, I am trying to locate documentation for CHef's Rest calls. Couldnt find any. I am using Chef 11 Open Source.

Any help/pointers on the above questions would be appreciated.

regards
