I was fortunate enough to have the opportunity to attend PuppetConf 2013. When I walked into the first keynote session, I was shocked by the size of the audience. Over 1300 people were packed into the ballroom. Another 3700 had signed up to watch the event streaming online. Last year there were 800 people at the conference and only 300 the year before. Obviously, both Puppet and DevOps are hot topics these days.
