#5 - Infrastructure as Code - Kief Morris

"With Infrastructure as Code, you’re not trying to kind of reverse engineer or understand what ended up somehow onto each system, you’re actually saying, this is how the system is built and because it’s built from that code. So there is no difference."

In this episode, I had an in-depth discussion with Kief Morris, the author of the O’Reilly “Infrastructure as Code” book. We started from what is Infrastructure as Code and why we should implement this important concept for managing our infrastructure, especially in the cloud era. We also discussed Infrastructure as Code principles, patterns, anti-patterns, pipeline, testing, and also recent new tools in this space. Kief also mentioned about his upcoming 2nd edition of the Infrastructure as Code book and what new changes that he is introducing. Do not miss our Pet vs Cattle discussion!
