This document is a summary of a webinar about infrastructure as code. It introduces the speaker, Srirajan, and discusses how automation tools like Chef, Puppet, Ansible and others can be used to define infrastructure in code. Key benefits of infrastructure as code include automation, repeatability, and disaster recovery. The webinar also discusses testing infrastructure code and version controlling code changes.
