It has been a while since the PuppetConf 2014 ended in San Francisco and there are lot of news that came out of it as usual. But, the biggest news is during the keynote that Luke Kanies, CEO of PuppetLabs announced there will be a new Puppet Server. A new Puppet Server? Yup. A Puppet Server and its not the same as our current Puppet Master. Curious on what this means I decided to check out the preview. All my opinions stated below are my own and does not reflect any of OlinData or PuppetLabs.
