/  NFVは別のモチベーションがあってアプローチ。 Overlay! 5分の⼿手作業より15分でコードを書きましょう Automation  is  the  new  skillset  that  network  engineers  need  to  pick  up.   Much  like  sysadmins  have  had  to  learn  how  to  use  new  tools  like  Chef   and  Puppet,  network  engineers  are  learning  that  they  just  can't  do   things  manually  anymore.  With  examples  in  each  chapter,  this  practical   book  provides  you  with  baseline  skills  in  network  programmability  and   automation,  using  a  range  of  technologies  including  Linux,  Python,   JSON,  and  XML.  No  previous  knowledge  of  software  development,   programming,  automation,  or  DevOps  is  required.
