I will show how my team has been using HashiCorp's Terraform for a year to manage our AWS infrastructure. I'll go over a small intro to Terraform, then jump into some internal design decisions, internal best practices, and a short demo to help solidify some of the principles. Kelvin is a Systems Engineer for Adobe where he is working in their Digital Marketing BU. There he has been using Terraform and Puppet to transform the way the ops team does business. Before that he was working as a "full stack" ops guy for MX where he racked servers, deployed code, and generally administered systems. He loves automation, making sure everything is committed to version control, and completing fulfilling and interesting projects. You can find him on Twitter @zxjinn.
