my heart cannot having to do the donkey work! So, I always automate what can be automated! Starting of Bash, AWK, Python ... and now Ansible!
I used Puppet for a while, but after trying Ansible, I fell in love with it! It's very simple and handy, agent-less, YAML syntax, orchestration ... simply it's Awesome! Not only admins love it, but developers too!
Last April, I made a "TechTalk" about Ansible. At eSapce, every Thursday one of the departments makes a session about new technology or something recently being used, and this was my session from SysOps team. It is an introduction to Ansible, and how to get started with it ... and since then we moved to Ansible :-)
If you are interesting in Ansible, you can find more resources on Ansible website to getting started with it.
