[chef] On-Demand Command Execution

[Howard Zhang < >]

Hi all, 

• On-Demand Command Execution: Private Chef delivers Push functionality as a Chef Server plugin that enables users to edit and execute command code in real time, increasing IT agility and control across ten or thousands of servers.

from #ChefConf 2013

Please could some one explain this feature to me? It really confuse me.

Cheers,
Howard Zhang
