Puppet does this work by providing system administrators a declarative language that allows a configurationfile to be described and then filled in differently based on the role that the computer on which theconfigurationfile exists is playing.
But the standby router picked the wrong configurationfile, which caused a drop in order flow, something the business users saw immediately with ITRS. Banks want to catch that sort of thing right away because their customers are monitoring execution and will divert their trades quickly if they see a problem.
