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

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

Cheers,
Howard Zhang
